Today, cloud infrastructure services utilize many individual services to build a data center (e.g., to bootstrap various resources in a data center of a particular geographic region). In some examples, a region is a logical abstraction corresponding to a localized geographical area in which one or more data centers are (or are to be) located. Building a data center may include provisioning and configuring infrastructure resources and deploying code to those resources (e.g., for a variety of services). The operations for building a data center may be collectively referred to as performing a “region build.” Any suitable number of data centers may be included in a region and therefore a region build may include operations for building multiple data centers. Conventional tools for building a region require significant manual effort. Additionally, bootstrapping operations for one service may depend on other functionality and/or services of the region which may not yet be available. As the number of service teams and regions grows, the tasks performed for orchestrating provisioning and deployment drastically increase. Substantially relying on manual efforts for bootstrapping services and/or building regions is time intensive, incurs risks, and may not scale well.
Embodiments of the present disclosure relate to a Resource Identification Service (e.g., a “Resource Hunter”) that is configured to identify previously existing resources (e.g., infrastructure component, artifacts, data etc.) that can be used to bootstrap a service in a region in lieu of creating a new resource. An orchestration service (e.g., a Multi-Flock Orchestrator) is disclosed that may orchestrate a region build process to bootstrap many services in a region. As part of the region build process, Multi-Flock Orchestrator can utilize the Resource Identification Service to identify previously existing resources and orchestrate bootstrapping operations such that the identified resources are utilized for bootstrapping operations in lieu of creating new resources.
At least one embodiment is directed to a computer-implemented method. The method may include obtaining, by a resource identification service of a cloud computing environment, a flock configuration file comprising resource discovery data associated with a service. In some embodiments, the resource discovery data indicates a set of parameters with which a previously existing resource of the cloud computing environment is to be identified. The method may further include executing, by the resource identification service, operations to identify the previously existing resource. In some embodiments, the previously existing resource may be identified based at least in part on matching attributes associated with each of the previously existing resource to the set of parameters of the resource discovery data. The method may further include identifying, by the resource identification service from the flock configuration file, a set of import operations to perform to store identifiers corresponding to the previously existing resource identified. The method may further include transmitting the identifier corresponding to the previously existing resource identified based at least in part on executing the set of import operations.

In the following description, for the purposes of explanation, specific details are set forth in order to provide a thorough understanding of certain embodiments. However, it will be apparent that various embodiments may be practiced without these specific details. The figures and description are not intended to be restrictive. The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any embodiment or design described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments or designs.
The adoption of cloud services has seen a rapid uptick in recent times. Various types of cloud services are now provided by various cloud service providers (CSPs). The term cloud service is generally used to refer to a service or functionality that is made available by a CSP to users or customers on demand (e.g., via a subscription model) using systems and infrastructure (cloud infrastructure) provided by the CSP. Typically, the servers and systems that make up the CSP's infrastructure and which is used to provide a cloud service to a customer are separate from the customer's own on-premise servers and systems. Customers can thus avail themselves of cloud services provided by the CSP without having to purchase separate hardware and software resources for the services. Cloud services are designed to provide a subscribing customer easy, scalable, and on-demand access to applications and computing resources without the customer having to invest in procuring the infrastructure that is used for providing the services or functions. Various different types or models of cloud services may be offered such as Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), Infrastructure-as-a-Service (IaaS), and others. A customer can subscribe to one or more cloud services provided by a CSP. The customer can be any entity such as an individual, an organization, an enterprise, and the like.
As indicated above, a CSP is responsible for providing the infrastructure and resources that are used for providing cloud services to subscribing customers. The resources provided by the CSP can include both hardware and software resources. These resources can include, for example, compute resources (e.g., virtual machines, containers, applications, processors), memory resources (e.g., databases, data stores), networking resources (e.g., routers, host machines, load balancers), identity, and other resources. In certain implementations, the resources provided by a CSP for providing a set of cloud services CSP are organized into data centers. A data center may be configured to provide a particular set of cloud services. The CSP is responsible for equipping the data center with infrastructure and resources that are used to provide that particular set of cloud services. A CSP may build one or more data centers.
Data centers provided by a CSP may be hosted in different regions. A region is a localized geographic area and may be identified by a region name. Regions are generally independent of each other and can be separated by vast distances, such as across countries or even continents. Regions are grouped into realms. Examples of regions for a CSP may include US West, US East, Australia East, Australia Southeast, and the like.
A region can include one or more data centers, where the data centers are located within a certain geographic area corresponding to the region. As an example, the data centers in a region may be located in a city within that region. For example, for a particular CSP, data centers in the US West region may be located in San Jose, Calif.; data centers in the US East region may be located in Ashburn, Va.; data centers in the Australia East region may be located in Sydney, Australia; data centers in the Australia Southeast region may be located in Melbourne, Australia; and the like.
Data centers within a region may be organized into one or more availability domains, which are used for high availability and disaster recovery purposes. An availability domain can include one or more data centers within a region. Availability domains within a region are isolated from each other, fault tolerant, and are architected in such a way that data centers in multiple availability domains are very unlikely to fail simultaneously. For example, the availability domains within a region may be structured in a manner such that a failure at one availability domain within the region is unlikely to impact the availability of data centers in other availability domains within the same region.
When a customer or subscriber subscribes to or signs up for one or more services provided by a CSP, the CSP creates a tenancy for the customer. The tenancy is like an account that is created for the customer. In certain implementations, a tenancy for a customer exists in a single realm and can access all regions that belong to that realm. The customer's users can then access the services subscribed to by the customer under this tenancy.
As indicated above, a CSP builds or deploys data centers to provide cloud services to its customers. As a CSP's customer base grows, the CSP typically builds new data centers in new regions or increases the capacity of existing data centers to service the customers' growing demands and to better serve the customers. Preferably, a data center is built in close geographical proximity to the location of customers serviced by that data center. Geographical proximity between a data center and customers serviced by that data center lends to more efficient use of resources and faster and more reliable services being provided to the customers. Accordingly, a CSP typically builds new data centers in new regions in geographical areas that are geographically proximal to the customers serviced by the data centers. For example, for a growing customer base in Germany, a CSP may build one or more data centers in a new region in Germany.
Building a data center (or multiple data centers) in a region is sometimes also referred to as building a region. The term “region build” is used to refer to building one or more data centers in a region. Building a data center in a region involves provisioning or creating a set of new resources that are needed or used for providing a set of services that the data center is configured to provide. The end result of the region build process is the creation of a data center in a region, where the data center is capable of providing a set of services intended for that data enter and includes a set of resources that are used to provide the set of services.
Building a new data center in a region is a very complex activity requiring coordination between various teams. At a high level, this involves the performance and coordination of various tasks such as: identifying the set of services to be provided by the data center, identifying various resources that are needed for providing the set of services, creating, provisioning, and deploying the identified resources, wiring the resources properly so that they can be used in an intended manner, and the like. Each of these tasks further have subtasks that need to be coordinated, further adding to the complexity. Due to this complexity, presently, the building of a data center in a region involves several manually-initiated or manually-controlled tasks that require careful manual coordination. As a result, the task of building a new region (i.e., building one or more data centers in a region) is very time consuming. It can take time, for example, many months to build a data center. Additionally, the process is very error prone, sometimes requiring several iterations before a desired configuration of the data center is achieved, which further adds to the time taken to build a data center. These limitations and problems severely limit a CSP's ability to grow in a timely manner responsive to increasing customer needs.
The present disclosure describes techniques for reducing the time and manual efforts needed for building one or more data centers in a region. This is made possible by automating several of the tasks that are involved in building a region. The automation significantly reduces the time needed to build a data center in a region and reduces the manual coordination that is needed. Instead of weeks and months needed to build a data center in a region in the past, the techniques described herein can be used to build a new data center in a region in a relatively much shorter time.
A Cloud Infrastructure Orchestration Service (CIOS) is disclosed herein that is configured to bootstrap (e.g., provision and deploy) services into a new data center based on predefined configuration files that identify the resources (e.g., infrastructure components and software to be deployed) for implementing a given change to the data center. The CIOS can identify dependencies between bootstrapping tasks using a static analysis of these configuration files. CIOS can use these dependencies to coordinate the order in which various changes are made to the new data center (e.g., the order by which services are bootstrapped in the region). The CIOS can detect various capabilities of the region as they become available which enables the system to identify and implement additional changes that can now be made to the region. Utilizing the techniques disclosed herein, the CIOS may optimize parallel processing to execute changes to the new data center while ensuring that tasks are not initiated until the functionality on which those tasks depend is available in the region. In this manner, the CIOS enables a region build to be performed as a substantially automated process, which greatly reduces the risk of error and time required in conventional systems.
During a region build, or at any suitable time, there may be any suitable number of resources (e.g., load balancers, databases, etc.) that may have been created during a previous region build (e.g., building of one or more data centers of a same or different region), or at least prior to the current region build. CIOS ensures that previously created resources (e.g., resources from another region) may be leveraged and used for bootstrapping purposes of the current region under build. A resource identification service (also referred to as a “Resource Hunter”) may be configured to attempt discovery of resources at any suitable time. In some embodiments, the functionality provided by the Resource Hunter may be triggered by a Multi-Flock Orchestrator such that previously-created resources (e.g., resources of a previously built region or data center) may be imported and utilized in the region under build. Although resources may be created out-of-band with the region build, these previously created resources can be automatically imported and utilized by the region build to avoid duplicate resources being created. Through leveraging these previously created resources, the techniques herein ensure that processing resources are not wasted creating resources that are not needed. This in turn enables a region build to be performed faster than otherwise would be possible if every resource were to be created anew.
A “region” is a logical abstraction corresponding to a geographical location. A region can include any suitable number of one or more execution targets. In some embodiments, an execution target could correspond to a data center.
An “execution target” refers to a unit of change for executing a release. A “release” refers to a representation of an intent to orchestrate a specific change to a service (e.g., deploy version 8, “add an internal DNS record,” etc.). For most services, an execution target represents is an “instance” of a service. A single service can be bootstrapped to each of one or more execution targets. An execution target may be associated with a set of devices (e.g., a data center).
“Bootstrapping” is intended to refer to the collective tasks associated with provisioning and deployment of any suitable number of resources (e.g., infrastructure components, artifacts, etc.) corresponding to a single service.
A “service” refers to functionality provided by a set of resources. A set of resources for a service includes any suitable combination of infrastructure, platform, or software (e.g., an application) hosted by a cloud provider that can be configured to provide the functionality of a service. A service can be made available to users through the Internet.
An “artifact” refers to code being deployed to an infrastructure component or a Kubernetes engine cluster, this may include software (e.g., an application), configuration information (e.g., a configuration file) for an infrastructure component, or the like.
A “flock config” refers to a configuration file (or a set of configuration files) that describes a set of all resources (e.g., infrastructure components and artifacts) associated with a single service. A flock config may include declarative statements that specify one or more aspects corresponding to a desired state of the resources of the service.
“Service state” refers to a point-in-time snapshot of every resource (e.g., infrastructure resources, artifacts, etc.) associated with the service. The service state indicates status corresponding to provisioning and/or deployment tasks associated with service resources.
IaaS provisioning (or “provisioning”) refers to acquiring computers or virtual hosts for use, and even installing needed libraries or services on them. The phrase “provisioning a device” refers to evolving a device to a state in which it can be utilized by an end-user for their specific use. A device that has undergone the provisioning process may be referred to as a “provisioned device.” Preparing the provisioned device (installing libraries and daemons) may be part of provisioning; this preparation is different from deploying new applications or new versions of an application onto the prepared device. In most cases, deployment does not include provisioning, and the provisioning may need to be performed first. Once prepared, the device may be referred to as “an infrastructure component.”
IaaS deployment (or “deployment”) refers to the process of providing and/or installing a new application, or a new version of an application, onto a provisioned infrastructure component. Once the infrastructure component has been provisioned (e.g., acquired, assigned, prepared, etc.), additional software may be deployed (e.g., provided to and installed on the infrastructure component). The infrastructure component can be referred to as a “resource” after provisioning and deployment has concluded. Examples of resources may include, but are not limited to, virtual machines, databases, object storage, block storage, load balancers, and the like.
A “capability” identifies a unit of functionality associated with a service. The unit could be a portion, or all, of the functionality to be provided by the service. By way of example, a capability can be published indicating that a resource is available for authorization/authentication processing (e.g., a subset of the functionality to be provided by the resource). As another example, a capability can be published indicating the full functionality of the service is available. Capabilities can be used to identify functionality on which a resource or service depends and/or functionality of a resource or service that is available for use.
A “virtual bootstrap environment” (ViBE) refers to a virtual cloud network that is provisioned in the overlay of an existing region (e.g., a “host region”). Once provisioned, a ViBE is connected to a new region using a communication channel (e.g., an IPSec Tunnel VPN). Certain essential core services (or “seed” services) like a deployment orchestrator, a public key infrastructure (PKI) service, and the like can be provisioned in a ViBE. These services can provide the capabilities required to bring the hardware online, establish a chain of trust to the new region, and deploy the remaining services in the new region. Utilizing the virtual bootstrap environment can prevent circular dependencies between bootstrapping resources by utilizing resources of the host region. Services can be staged and texted in the ViBE prior to the physical region (e.g., the target region) being available.
A “Cloud Infrastructure Orchestration Service” (CIOS) may refer to a system configured to manage provisioning and deployment operations for any suitable number of services as part of a region build.
A Multi-Flock Orchestrator (MFO) may be a computing component (e.g., a service) configured that coordinates events between components of the CIOS to automatically provision and deploy services to a target region (e.g., a new region). An MFO tracks relevant events for each service of the region build and takes actions in response to those events.
A “host region” refers to a region that hosts a virtual bootstrap environment (ViBE). A host region may be used to bootstrap a ViBE.
A “target region” refers to a region under build.
“Publishing a capability” refers to “publishing” as used in a “publisher-subscriber” computing design or otherwise providing an indication that a particular capability is available (or unavailable). The capabilities are “published” (e.g., collected by a capabilities service, provided to a capabilities service, pushed, pulled, etc.) to provide an indication that functionality of a resource/service is available. In some embodiments, capabilities may be published/transmitted via an event, a notification, a data transmission, a function call, an API call, or the like. An event (or other notification/data transmission/etc.) indicating availability of a particular capability can be broadcasted/addressed (e.g., published) to a capabilities service.
A “Capabilities Service” may be a flock configured to model dependencies between different flocks. A capabilities service may be provided within a Cloud Infrastructure Orchestration Service and may define what capabilities, services, features have been made available in a region.
A “Real-time Regional Data DistributorDistributor” (RRDD) can be a service or system configured to manage region data. This region data can be injected into flock configs to dynamically create execution targets for new regions.
In some examples, techniques for implementing a Cloud Infrastructure Orchestration Service (CIOS) are described herein. Such techniques, as described briefly above, can be configured to manage bootstrapping (e.g., provisioning and deploying software to) infrastructure components within a cloud environment (e.g., a region). In some instances, the CIOS can include computing components (e.g., a CIOS Central and a CIOS Regional, both of which will be described in further detail below) that may be configured to manage bootstrapping tasks (provisioning and deployment) for a given service and a Multi-Flock Orchestrator (also described in further detail below) configured to initiate/manage region builds (e.g., bootstrapping operations corresponding to multiple services).
CIOS enables region building and world-wide infrastructure provisioning and code deployment with minimal manual run-time effort from service teams (e.g., beyond an initial approval and/or physical transportation of hardware, in some instances). The high-level responsibilities of CIOS include, but are not limited to, coordinating region builds in an automated fashion with minimal human intervention, providing users with a view of the current state of resources managed by the CIOS (e.g., of a region, across regions, world-wide, etc.), and managing bootstrapping operations for bootstrapping resources within a region.
The CIOS may provide view reconciliation, where a view of a desired state (e.g., a desired configuration) of resources may be reconciled with a current/actual state (e.g., a current configuration) of the resources. In some instances, view reconciliation may include obtaining state data to identify what resources are actually running and their current configuration and/or state. Reconciliation can be performed at a variety of granularities, such as at a service level.
CIOS can perform plan generation, where differences between the desired and current state of the resources are identified. Part of plan generation can include identifying the operations that would need to be executed to bring the resources from the current state to the desired state. Once the user is satisfied with a plan, the plan can then be marked as approved or rejected. Thus, users can spend less time reasoning about the plan and the plans are more accurate because they are machine generated. Plans are almost too detailed for human consumption; however, CIOS can provide this data via a sophisticated user interface (UI).
In some examples, CIOS can handle execution of change management by automatically executing the approved plan. Once an execution plan has been created and approved, engineers may no longer need to participate in change management unless CIOS initiates roll-back. CIOS can handle rolling back to a previous service version by automatically generating a plan that returns the service to a previous (e.g., pre-release) state (e.g., when CIOS detects service health degradation while executing).
CIOS can measure service health by monitoring alarms and executing integration tests. CIOS can help teams quickly define roll-back behavior in the event of service degradation, which it can later execute automatically. CIOS can automatically generate and display plans and can track approval. CIOS can combine the functionality of provisioning and deployment in a single system that coordinates these tasks across a region build. CIOS also supports automated discovery of flocks (e.g., service resources such as flock config(s) corresponding to any suitable number of services), artifacts, resources, and dependencies. CIOS can discover dependencies between execution tasks at every level (e.g., resource level, execution target level, phase level, service level, etc.) through a static analysis (e.g., including parsing and processing content) of one or more configuration files. Using these dependencies, CIOS can generate various data structures from these dependencies that can be used to drive task execution (e.g., tasks regarding provisioning of infrastructure resources and deployment of artifacts across the region).
Real-time Regional Data Distributor (RRDD) 104 may be configured to maintain and provide region data that identifies realms, regions, execution targets, and availability domains. In some cases, the region data may be in any suitable form (e.g., JSON format, data objects/containers, XML, etc.). Region data maintained by RRDD 104 may include any suitable number of subsets of data which can individually be referenceable by a corresponding identifier. By way of example, an identifier “all_regions” can be associated with a data structure (e.g., a list, a structure, an object, etc.) that includes a metadata for all defined regions. As another example, an identifier such as “realms” can be associated with a data structure that identifies metadata for a number of realms and a set of regions corresponding to each realm. In general, the region data may maintain any suitable attribute of one or more realm(s), region(s), availability domains (ADs), execution target(s) (ETs), and the like, such as identifiers, DNS suffixes, states (e.g., a state of a region), and the like. The RRDD 104 may be configured to manage region state as part of the region data. A region state may include any suitable information indicating a state of bootstrapping within a region. By way of example, some example region states can include “initial,” “building,” “production,” “paused,” or “deprecated.” The “initial” state may indicate a region that has not yet been bootstrapped. A “building” state may indicate that bootstrapping of one or more flocks within the region has commenced. A “production” state may indicate that bootstrapping has been completed and the region is ready for validation. A “paused” state may indicate that CIOS Central 108 or CIOS Regional 110 has paused internal interactions with the regional stack, likely due to an operational issue. A “deprecated” state may indicate the region has been deprecated and is likely unavailable and/or will not be contacted again.
CIOS Central 108 is configured to provide any suitable number of user interfaces with which users (e.g., user 109) may interact with CIOS 102. By way of example, users can make changes to region data via a user interface provided by CIOS Central 108. CIOS Central 108 may additionally provide a variety of interfaces that enable users to: view changes made to flock configs and/or artifacts, generate and view plans, approve/reject plans, view status on plan execution (e.g., corresponding to tasks involving infrastructure provisioning, deployment, region build, and/or desired state of any suitable number of resources managed by CIOS 102. CIOS Central 108 may implement a control plane configured to manage any suitable number of CIOS Regional 110 instances. CIOS Central 108 can provide one or more user interfaces for presenting region data, enabling the user 109 to view and/or change region data. CIOS Central 108 can be configured to invoke the functionality of RRDD 104 via any suitable number of interfaces. Generally, CIOS Central 108 may be configured to manager region data, either directly or indirectly (e.g., via RRDD 104). CIOS Central 108 may be configured to compile flock configs to inject region data as variables within the flock configs.
Each instance of CIOS Regional 110 may correspond to a module configured to execute bootstrapping tasks that are associated with a single service of a region. CIOS Regional 110 can receive desired state data from CIOS Central 108. In some embodiments, desired state data may include a flock config that declares (e.g., via declarative statements) a desired state of resources associated with a service. CIOS Central 108 can maintain current state data indicating any suitable aspect of the current state of the resources associated with a service. In some embodiments, CIOS Regional 110 can identify, through a comparison of the desired state data and the current state data, that changes are needed to one or more resources. For example, CIOS Regional 110 can determine that one or more infrastructure components need to be provisioned, one or more artifacts deployed, or any suitable change needed to the resources of the service to bring the state of those resources in line with the desired state. As CIOS Regional 110 performs bootstrapping operations, it may publish data indicating various capabilities of a resource as they become available. A “capability” identifies a unit of functionality associated with a service. The unit could be a portion, or all of the functionality to be provided by the service. By way of example, a capability can be published indicating that a resource is available for authorization/authentication processing (e.g., a subset of the functionality to be provided by the resource). As another example, a capability can be published indicating the full functionality of the service is available. Capabilities can be used to identify functionality on which a resource or service depends and/or functionality of a resource or service that is available for use.
Capabilities Service 112 is configured to maintain capabilities data that indicates 1) what capabilities of various services are currently available, 2) whether any resource/service is waiting on a particular capability, 3) what particular resources and/or services are waiting on a given capability, or any suitable combination of the above. Capabilities Service 112 may provide an interface with which capabilities data may be requested. Capabilities Service 112 may provide one or more interfaces (e.g., application programming interfaces) that enable it to transmit capabilities data to MFO 106 and/or CIOS Regional 110 (e.g., each instance of CIOS Regional 110). In some embodiments, MFO 106 and/or any suitable component or module of CIOS Regional 110 may be configured to request capabilities data from Capabilities Service 112.
In some embodiments, Multi-Flock Orchestrator (MFO) 106 may be configured to drive region build efforts. In some embodiments, WO 106 can manage information that describes what flock/flock config versions and/or artifact versions are to be utilized to bootstrap a given service within a region (or to make a unit of change to a target region). In some embodiments, MFO 106 may be configured to monitor (or be otherwise notified of) changes to the region data managed by Real-time Regional Data Distributor 104. In some embodiments, receiving an indication that region data has been changed may cause a region build to be triggered by MFO 106. In some embodiments, WO 106 may collect various flock configs and artifacts to be used for a region build. Some, or all, of the flock configs may be configured to be region agnostic. That is, the flock configs may not explicitly identify what regions to which the flock is to be bootstrapped. In some embodiments, MFO 106 may trigger a data injection process through which the collected flock configs are recompiled (e.g., by CIOS Central 108). During recompilation, operations may be executed (e.g., by CIOS Central 108) to cause the region data maintained by Real-time Regional Data Distributor 104 to be injected into the config files. Flock configs can reference region data through variables/parameters without requiring hard-coded identification of region data. The flock configs can be dynamically modified at run time using this data injection rather than having the region data be hardcoded, and therefore, and more difficult to change.
Multi-Flock Orchestrator 106 can perform a static flock analysis in which the flock configs are parsed to identify dependencies between resources, execution targets, phases, and flocks, and in particular to identify circular dependencies that need to be removed. In some embodiments, MFO 106 can generate any suitable number of data structures based on the dependencies identified. These data structures (e.g., directed acyclic graph(s), linked lists, etc.) may be utilized by the Cloud Infrastructure Orchestration Service 102 to drive operations for performing a region build. By way of example, these data structures may collectively define an order by which services are bootstrapped within a region. An example of such a data structure is discussed further below with respect to Build Dependency Graph 338 of
In some embodiments, a user can request that a new region (e.g., target region 114) be built. This can involve bootstrapping resources corresponding to a variety of services. In some embodiments, target region 114 may not be communicatively available (and/or secure) at a time at which the region build request is initiated. Rather than delay bootstrapping until such time as target region 114 is available and configured to perform bootstrapping operations, CIOS 102 may initiate the region build using a virtual bootstrap environment 116. Virtual bootstrap environment (ViBE) 116 may be an overlay network that is hosted by host region 103 (a preexisting region that has previously been configured with a core set of services and which is communicatively available and secure). MFO 106 can leverage resources of the host region 103 to bootstrap resources to the ViBE 116 (generally referred to as “building the ViBE”). By way of example, MFO 106 can provide instructions through CIOS Central 108 that cause an instance of CIOS Regional 110 within a host region (e.g., host region 103) to bootstrap another instance of CIOS Regional within the ViBE 116. Once the CIOS Regional within the ViBE is available for processing, bootstrapping the services for the target region 114 can continue within the ViBE 116. When target region 114 is available to perform bootstrapping operations, the previously bootstrapped services within ViBE 116 may be migrated to target region 114. Utilizing these techniques, CIOS 102 can greatly improve the speed at which a region is built by drastically reducing the need for any manual input and/or configuration to be provided.
In order to bootstrap a new region (e.g., target region 114 of
When the target region is available to provide bootstrapping operations, the ViBE 202 can be connected to the target region so that services in the ViBE can interact with the services and/or infrastructure components of the target region. This will enable deployment of production level services, instead of self-contained seed services as in previous systems, and will require connectivity over the interne to the target region. Conventionally, a seed service was deployed as part of a container collection and used to bootstrap dependencies necessary to build out the region. Using infrastructure/tooling of an existing region, resources may be bootstrapped (e.g., provisioned and deployed) into the ViBE 202 and connected to the service enclave of a region (e.g., host region 204) in order to provision hardware and deploy services until the target region is self-sufficient and can be communicated with directly. Utilizing the ViBE 202 allows for standing up the dependencies and services needed to be able to provision/prepare infrastructure and deploy software while making use of the host region's resources in order to break circular dependencies of core services.
Multi-Flock Orchestrator (MFO) 206 may be configured to perform operations to build (e.g., configure) ViBE 202. MFO 206 can obtain applicable flock configs corresponding to various resources to be bootstrapped to the new region (in this case, a ViBE region, ViBE 202). By way of example, MFO 206 may obtain a flock config (e.g., a “ViBE flock config”) that identifies aspects of bootstrapping Capabilities Service 208 and Worker 210. As another example, MFO 206 may obtain another flock config corresponding to bootstrapping Domain Name Service (DNS) 212 to ViBE 202.
At step 1, MFO 206 may instruct CIOS Central 214 (e.g., an example of CIOS Central 108 and CIOS Central 214 of
At step 2, CIOS Central 214 may provide the ViBE flock config via a corresponding request to CIOS Regional 216. CIOS Regional 216 may parse the ViBE flock config to identify and execute specific infrastructure provisioning and deployment operations at step 3.
In some embodiments, the CIOS Regional 216 may utilize additional corresponding services for provisioning and deployment. For example, at step 4, CIOS Regional 216 CIOS Regional may instruct deployment orchestrator 218 (e.g., an example of a core service, or other write, build, and deploy applications software, of the host region 204) to execute instructions that in turn cause Capabilities Service 208 and Worker 210 to be bootratpped within ViBE 202.
At step 5, a capability may be transmitted to the Capabilities Service 208 (from the CIOS Regional 216, Deployment Orchestrator 218 via the Worker 210 or otherwise) indicating that resources corresponding to the ViBE flock are available. Capabilities Service 208 may persist this data. In some embodiments, the Capabilities Service 208 adds this information to a list it maintains of available capabilities with the ViBE. By way of example, the capability provided to Capabilities Service 208 at step 5 may indicate the Capabilities Service 208 and Worker 210 are available for processing.
At step 6, MFO 206 may identify that the capability indicating that Capabilities Service 208 and Worker 210 are available based on receiving or obtaining data (an identifier corresponding to the capability) from the Capabilities Service 208.
At step 7, as a result of receiving/obtaining the data at step 6, the WO 206 may instruct CIOS Central 214 to bootstrap a DNS service (e.g., DNS 212) to the ViBE 202. The instructions may identify or include a particular flock config corresponding to the DNS service.
At step 8, the CIOS Central 214 may instruct the CIOS Regional 216 to deploy DNS 212 to the ViBE 202. In some embodiments, the DNS flock config for the DNS 212 is provided by the CIOS Central 214.
At step 9, Worker 210, now that it is deployed in the ViBE 202, may be assigned by CIOS Regional 216 to the task of deploying DNS 212. Worker may execute a declarative infrastructure provisioner in the manner described above in connection with
At step 10, the Deployment Orchestrator 218 may instruct Worker 210 to deploy DNS 212 in accordance with the operations identified at step 9. As depicted, Worker 210 proceeds with executing operations to deploy DNS 212 to ViBE 202 at step 11. At step 12, Worker 210 notifies Capabilities Service 208 that DNS 212 is available in ViBE 202. MFO 206 may subsequently identify that the resources associated with the ViBE flock config and the DNS flock config are available any may proceed to bootstrap any suitable number of additional resources to the ViBE.
After steps 1-12 are concluded, the process for building the ViBE 202 can be considered complete and the ViBE 202 can be considered built.
At step 1, user 302 may utilize any suitable user interface provided by CIOS Central 304 (an example of CIOS Central 108 and CIOS Central 214 of
At step 2, CIOS Central 304 may execute operations to send the change to RRDD 306 (e.g., an example of RRDD 104 of
At step 4, MFO 310 (an example of the MFO 106 and 206 of
At step 5, detecting the change in region data may trigger MFO 310 to obtain a version set (e.g., a version set associated with a particular identifier such as a “golden version set” identifier). identifying a particular version for each flock (e.g., service) that is to be bootstrapped to the new region and a particular version for each artifact corresponding to that flock. The version set may be obtained from DB 312. As flocks evolve and change, the versions for their corresponding configs and artifacts used for region build may change. These changes may be persisted in flock DB 312 such that MFO 310 may identify which versions of flock configs and artifacts to use for building a region (e.g., a ViBE region, a Target Region/non-ViBE Region, etc.). The flock configs (e.g., all versions of the flock configs) and/or artifacts (e.g., all versions of the artifacts) may be stored in DB 308, DB 312, or any suitable data store accessible to the CIOS Central 304 and/or MFO 310.
At step 6, MFO 310 may request CIOS Central 304 to recompile of each of the flock configs associated with the version set with the current region data. In some embodiments, the request may indicate a version for each flock config and/or artifact corresponding to those flock configs.
At step 7, CIOS Central 304 may obtain current region data from the DB 308 (e.g., directly, or via Real-time Regional Data Distributor 306) and retrieve any suitable flock config and artifact in accordance with the versions requested by MFO 310.
At step 8, CIOS Central 304 may recompile the flock configs with the region data obtained at step 7 to inject the flock configs with current region data. CIOS Central 304 may return the compiled flock configs to MFO 310. In some embodiments, CIOS Central 304 may simply indicate compilation is done, and MFO 310 may access the recompiled flock configs via RRDD 306.
At step 9, MFO 310 may perform a static analysis of the recompiled flock configs. As part of the static analysis, WO 310 may parse the flock configs (e.g., using a library associated with a declarative infrastructure provisioner (e.g., Terraform, or the like)) to identify dependencies between flocks. From the analysis and the dependencies identified, MFO 310 can generate Build Dependency Graph 338. Build Dependency Graph 338 may be an acyclic directed graph that identifies an order by which flocks are to be bootstrapped (and/or changes indicated in flock configs are to be applied) to the new region. Each node in the graph may correspond to bootstrapping any suitable protion of a particular flock. The specific bootstrapping order may be identified based at least in part on the dependencies. In some embodiments, the dependencies may be expressed as an attribute of the node and/or indicated via edges of the graph that connect the nodes. MFO 310 may traverse the graph (e.g., beginning at a starting node) to drive the operations of the region build.
In some embodiments, MFO 310 may utilize a cycle detection algorithm to detect the presence of a cycle (e.g., service A depends on service B and vice versa). MFO 310 can identify orphaned capabilities dependencies. For example, MFO 310 can identify orphaned nodes of the Build Dependency Graph 338 that do not connect to any other nodes. MFO 310 may identify falsely published capabilities (e.g., when a capability was prematurely published and the corresponding functionality is not actually yet available). WO 310 can detect from the graph that one or more instances of publishing the same capability exist. In some embodiments, any suitable number of these errors may be detected and WO 310 (or another suitable component such as CIOS Central 304) may be configured to notify or otherwise present this information to users (e.g., via an electronic notification, a user interface, or the like). In some embodiments, MFO 310 may be configured to force delete/recreate resources to break circular dependencies and may once again provide instructions to CIOS Central 304 to perform bootstrapping operations for those resources and/or corresponding flock configs.
A starting node may correspond to bootstrapping the ViBE flock, a second node may correspond to bootstrapping DNS. The steps 10-15 correspond to deploying (via deployment orchestrator 317, an example of the deployment orchestrator 218 of
By way of example, MFO 310 may continue traversing the Build Dependency Graph 338 to identify that a DNS flock is to be deployed. Steps 16-21 may be executed to deploy DNS 322 (an example of the DNS 212 of
At step 21, a capability may be stored indicating that DNS 322 is available. Upon detecting this capability, MFO 310 may recommence traversal of the Build Dependency Graph 338. On this traversal, the MFO 310 may identify that any suitable portion of an instance of CIOS Regional (e.g., an example of CIOS Regional 314) is to be deployed to the ViBE 316. In some embodiments, steps 16-21 may be substantially repeated with respect to deploying CIOS Regional (ViBE) 326 (an instance of CIOS Regional 314, CIOS Regional 110 of
Upon detecting the CIOS Regional (ViBE) 326 is available, MFO 310 may recommence traversal of the Build Dependency Graph 338. On this traversal, the MFO 310 may identify that a deployment orchestrator (e.g., Deployment Orchestrator 330, an example of the Deployment Orchestrator 317) is to be deployed to the ViBE 316. In some embodiments, steps 16-21 may be substantially repeated with respect to deploying Deployment Orchestrator 330. Information that identifies a capability may be transmitted to the Capabilities Service 318, indicating that Deployment Orchestrator 330 is available.
After Deployment Orchestrator 330 is deployed, ViBE 316 may be considered available for processing subsequent requests. Upon detecting Deployment Orchestrator 330 is available, MFO 310 may instruct subsequent bootstrapping requests to be routed to ViBE components rather than utilizing host region components (components of host region 332). Thus, MFO 310 can continue traversing the Build Dependency Graph 338, at each node instructing flock deployment to the ViBE 316 via CIOS Central 304. CIOS Central 304 may request CIOS Regional (ViBE) 326 to deploy resources according to the flock config.
At some point during this process, Target Region 334 may become available. Indication that the Target Region is available may be identifiable from region data for the Target Region 334 being provided by the user 302 (e.g., as an update to the region data). The availability of Target Region 334 may depend on establishing a network connection between the Target Region 334 and external networks (e.g., the Internet). The network connection may be supported over a public network (e.g., the Internet), but use software security tools (e.g., IPSec) to provide one or more encrypted tunnels (e.g., IPSec tunnels such as tunnel 336) from the ViBE 316 to Target Region 334. As used herein, “IPSec” refers to a protocol suite for authenticating and encrypting network traffic over a network that uses Internet Protocol (IP) and can include one or more available implementations of the protocol suite (e.g., Openswan, Libreswan, strongSwan, etc.). The network may connect the ViBE 316 to the service enclave of the Target Region 334.
Prior to establishing the IPSec tunnels, the initial network connection to the Target Region 334 may be on a connection (e.g., an out-of-band VPN tunnel) sufficient to allow bootstrapping of networking services until an IPSec gateway may be deployed on an asset (e.g., bare-metal asset) in the Target Region 334. To bootstrap the Target Region's 334 network resources, Deployment Orchestrator 330 can deploy the IPSec gateway at the asset within Target Region 334. The Deployment Orchestrator 330 may then deploy VPN hosts at the Target Region 334 configured to terminate IPSec tunnels from the ViBE 316. Once services (e.g., Deployment Orchestrator 330, Service A, etc.) in the ViBE 316 can establish an IPSec connection with the VPN hosts in the Target Region 334, bootstrapping operations from the ViBE 316 to the Target Region 334 may begin.
In some embodiments, the bootstrapping operations may begin with services in the ViBE 316 provisioning resources in the Target Region 334 to support hosting instances of core services as they are deployed from the ViBE 316. For example, a host provisioning service may provision hypervisors on infrastructure (e.g., bare-metal hosts) in the Target Region 334 to allocate computing resources for VMs. When the host provisioning service completes allocation of physical resources in the Target Region 334, the host provisioning service may publish information indicating a capability that indicates that the physical resources in the Target Region 334 have been allocated. The capability may be published to Capabilities Service 318 via CIOS Regional (ViBE) 326 (e.g., by Worker 328).
With the hardware allocation of the Target Region 334 established and posted to capabilities service 318, CIOS Regional (ViBE) 326 can orchestrate the deployment of instances of core services from the ViBE 316 to the Target Region 334. This deployment may be similar to the processes described above for building the ViBE 316, but using components of the ViBE (e.g., CIOS Regional (ViBE) 326, Worker 328, Deployment Orchestrator 330) instead of components of the Host Region 332 service enclave. The deployment operations may generally correspond to steps 16-21 described above.
As a service is deployed from the ViBE 316 to the Target Region 334, the DNS record associated with that service may correspond to the instance of the service in the ViBE 316. The DNS record associated with the service may be updated at a later time to complete deployment of the service to the Target Region 334. Said another way, the instance of the service in the ViBE 316 may continue to receive traffic (e.g., requests) to the service until the DNS record is updated. A service may deploy partially into the Target Region 334 and publish information indicating a capability (e.g., to Capabilities Service 318) that the service is partially deployed. For example, a service running in the ViBE 316 may be deployed into the Target Region 334 with a corresponding compute instance, load balancer, and associated applications and other software, but may need to wait for database data to migrate to the Target Region 334 before being completely deployed. The DNS record (e.g., managed by DNS 322) may still be associated with the service in the ViBE 316. Once data migration for the service is complete, the DNS record may be updated to point to the operational service deployed in the Target Region 334. The deployed service in the Target Region 334 may then receive traffic (e.g., requests) for the service, while the instance of the service in the ViBE 316 may no longer receive traffic for the service.
Environment 500 may include Resource Hunter (RH) 420 (also referred to as a “Resource Identification Service”). RH 420 may be configured to attempt discovery of resources at any suitable time. By way of example, any suitable number of resources may exist in any suitable region prior to a region build of that, or another region. By way of example, resource(s) 422 may include any suitable number of resources (e.g., infrastructure resources, artifacts, configuration files, etc.) that exist in the host region 403 (an example of the host region 103, 204, and/or 332 of
RH 420 may be configured to receive flock config information from MFO 406 (and/or any suitable component of the CIOS 402 and/or any service bootstrapped within the Host Region 403, the ViBE 416, and/or the Target Region 414). In some embodiments, MFO 406 may provide an identifier of the flock and RH 420 may be configured to access corresponding flock config files associated with that flock. Alternatively, MFO 406 may provide the flock config to RH 420. An example flock config is discussed in more detail in connection with
RH 420 may identify resource discovery data within the flock config. “Resource discovery data” refers to any suitable data (e.g., a set of parameters) with which a previously existing resource (e.g., one or more of resource(s) 422-426) may be identified. RH 420 may execute operations to identify any suitable number of the resource(s) 422-426 utilizing the set of parameters of the resource discovery data. For example, RH 420 may search (e.g., within a region specified by the resource discovery data and/or globally) for particular resources that are associated with attributes that match the set of parameters provided in the resource discovery data. If one or more matching resources are discovered, RH 420 may provide the identifier(s) for the matching resource(s) to MFO 406 directly, and/or RH 420 may store the identifier(s) within a record accessible to MFO 406.
MFO 406 may include a State Manager 428. The State Manager 428 may be configured to implement a state machine that transitions between states to drive a pass. By way of example, a single flock may require multiple releases (e.g., multiple transmissions of instructions to CIOS Central 408, multiple releases corresponding to one or more flock configs associated with a single service, etc.). State Manager 428 may be configured to coordinate the operations performed for a single release. This may include monitoring for messages from CIOS Central 408 and/or Resource Hunter 420. In some embodiments, the State Manager 428 may be configured to monitor for one or more capabilities transmitted by Capabilities Service 412. The operations performed by the State Manager 428 may be discussed in further detail with respect to
In some embodiments, code segment 502 may include resource discovery data that may be utilized to identify one or more previously existing resources. By way of example, the line 506 may indicate that data corresponding to a resource of type “dataType” and name “Resource_Name” is to be searched for. Type “dataType” and named “Resource_Name” may be considered parameters of the resource discovery data defined by code segment 502. Lines 507-508 may each include additional parameters with which the search is to be conducted. For example, line 507 may include a parameter “ad” which, as depicted, may be populated with the name of each availability domain of a region (e.g., via a locally accessible array or list). Line 508 may include a parameter “compartment_id” which, as depicted, is populated with an identifier corresponding to every compartment of the region. Line 509 may define a string value (e.g., “EXAMPLE_RESOURCE”) that may be used locally within flock config 500. The user of the string value defined at line 509 is discussed in further detail below.
As line 507 and 508 utilize a local parameter (e.g., indicated through the use of “local.”, respectively), in some embodiments, region data values corresponding to the names of all of the availability domains of a given region and all compartment identifiers with the region may be injected within parameter “ad” and “compartment_id,” respectively. The process in which the region data values are injected within local parameters is discussed in more detail in connection to U.S. Provisional Application No. 63/315,024, filed Feb. 28, 2022, entitled “DATA MANAGEMENT TECHNIQUES FOR CLOUD REGIONS” (Attorney Docket No. 088325-1282326 (306000US), the contents of which are incorporated here in their entirety for all purposes. In the example depicted in
Based at least in part on code segment 502, RH 420 may search every availability domain, in every compartment of that availability domain for resources that are associated with a data type “dataType,” a name “Resource_Name.” The parameter “data” may be utilized to access the resources identified, if any were found.
Code segment 504, as depicted, provides import operations to be executed with the resources identified using the parameters of code segment 502. RH 420 may be configured to execute any suitable operations defined with a declaration such as indicate in line 510 (e.g., output “default imports”). In the example depicted in code segment 504, at line 512, RH 420 may obtain a value for each resource identified as matching the set of parameters provided in code segment 502. The string “EXAMPLE_RESOURCE” may be utilized a string to replace a portion of line 510 (e.g., “example_resource”) with “EXAMPLE_RESOURCE” as depicted at 511. In this manner, a global variable (e.g., a string, an integer, etc.) may be defined in code segment 502 and then utilized by any suitable portion of flock config 500 (e.g., code segment 504) as depicted at 511, 513, and 515.
For each resource, the value parameter at line 512 may be set to the value corresponding to data. EXAMPLE_RESOURCE.instance. Using the value for one resource, the operations of lines 514 and 516 may be executed. Line 514, when executed, may obtain the resource's address (e.g., an IP address). Line 516, when executed, may obtain an identifier for the resource. After executing lines 514 and 516 for each resource identified, RH 420 may have a list of the addresses and/or identifiers for every resource that was found to have attributes that matched the set of parameters of code segment 502. The RH 420 may store these address/identifiers in a record accessible to the MFO of

At 614, while in the AWAITING_RELEASE state, MFO 602 may be configured to begin traversal of the Build Dependency Graph (e.g., the Build Dependency Graph 338 of
At 616, the MFO 602 may send a set of instructions corresponding of a release of the first flock config. In some embodiments, WO 602 may send a first request to CIOS Central 604 with the first flock config that, as previously discussed, includes injected region data. Once sent, MFO 602 (e.g., the state manager 428) may transition to state AWAITING_PLAN (corresponding to awaiting_plan state 708 of
At 618, CIOS Central 604 may receive the flock config and may perform operations for planning the release. By way of example, CIOS Central 604 may attempt to ascertain the state of the resources in the first flock config within the ViBE region 316. CIOS Central 604 may identify that an instance of CIOS Regional and Deployment Orchestrator are needed to bootstrap the resources identified in the first flock config (e.g., Capabilities Service 318 and Worker 320). As the ViBE region 316 is new, CIOS Central 604 may identify that none of the resources needed for the flock exist. In response, CIOS Central 604 may generate planning data 620.
At 624, WO 602 may, upon receiving planning data 620, send a request to Resource Hunter 606 (e.g., an example of Resource Hunter 420 of
At 628, Resource Hunter 606 may extract the parameters from the resource discovery data provided in the first flock config (e.g., code segment 502). In some embodiments, Resource Hunter 606 may perform any suitable operations to query at a location specified by the resource discovery data (e.g., as defined in code segment 502, each AD, in each compartment, etc.) and/or with any suitable combination of the parameters provided (e.g., “dataType,” “Resource_Name” as provided in code segment 502.
At 630, Resource Hunter 606 may transmit to MFO 602, any suitable data indicating any suitable number of resources identified as matching the resource discovery data. WO 602 may send another request at 632 to request that Resource Hunter 606 perform import operations.
At 634, upon receiving the data at 630, MFO 602 (e.g., the State Manager 428) may transition to state AWAITING_IMPORT corresponding to the awaiting_mport state 714 of
At 636, Resource Hunter 606 may be configured to identify a set of import operations to be performed. By way of example, Resource Hunter 606 may identify import operations from the first flock config within the resource discovery data provided. By way of example, Resource Hunter 606 may identify code segment 504 of

At 642, MFO 602 may perform operations for updating the state data of the planning data 620. Referring once more to
Returning to
At 646, MFO 602 may send the modified planning data including state data 810 of
At 648, CIOS Central 604 may updated planning data and may perform operations for replanning the release using the updated planning data provided by MFO 602. Planning Data 650 may be generated as part of those operations. Planning Data 650 may identify resources to be created. In the ongoing example, CIOS Regional 314 and Deployment Orchestrator 317 either may not be included in the planning data 650, or if they are, the planning data 650 may indicate they are to be used instead of creating a new resource.
At 652, MFO 602 may receive the planning data 650 and may compare the planning data 650 to the state data it sent at 646 to determine whether the planning data 650 is in line with the requested state data. For example, WO 602 may verify from the planning data 650 that CIOS Central 604 does not plan to generate a new instance of CIOS Regional, but rather intends to use the CIOS Regional 314 of Host Region 332. Similarly, MFO may verify from the planning data 650 that CIOS Central 604 does not plan to generate a new instance of Deployment Orchestrator 317, but rather intends to use the Deployment Orchestrator 317 of Host Region 332.
At 654, if the planning data 650 is in line with the state data sent at 646, MFO 602 (e.g., the State Manager 428) may transition to state AWAITING_APPROVAL corresponding to the awaiting_approval state 720 of
At 662, CIOS Central 604 may perform any suitable operations for bootstrapping the resources of the first flock config within the region in build (e.g., ViBE 316 of
At 664, MFO 602 may receive (or otherwise obtain) an indication that the capability corresponding to the Capabilities Service 318 has been published. In response, to identifying that the published capability is identified in the flock config, the WO 602 (e.g., the State Manager 428) may transition, at 667, to state SUCCESSFUL corresponding to the awaiting_completion state 720 of
This may conclude a single pass (also called a “release”) of a flock config to the region (e.g., the ViBE 316). Once the successful state is reached, WO 602 may be configured to resume traversal of the Build Dependency Graph 338 to identify the next release/pass. This process may be performed any suitable times, the specific flock configs can include any suitable discovery data with which resources of the region (or another region) may be imported and utilized (e.g., by the CIOS Regional in that region).
A similar process may be performed to deploy an instance of Capabilities Service, Deployment Orchestrator, CIOS Regional, and Worker in a Target Region. Once the user added the region data corresponding to the Target Region (e.g., Target Region 334), a different set of flock configs would be identified by MFO. Any suitable portion of these flock configs may include resource discovery data that, at times, may cause MFO 602 to instruct CIOS Central that resources of the ViBE are to be used for bootstrapping operations performed for the Target Region.
Returning to
The method 900 may begin at 902, where a flock configuration file (e.g., flock configuration file 500) comprising resource discovery data associated with a service may be obtained (e.g., by a resource identification service such as the Resource Hunter 420 of
At 904, operations to identify the previously existing resource may be executed. In some embodiments, the previously existing resource (e.g., CIOS Regional 314 as discussed in the example of
At 906, a set of import operations to perform to obtain an identifier corresponding to the previously existing resource may be identified. By way of example,
At 908, the identifiers corresponding to the previously existing resource identified may be transmitted (e.g., to MFO 602 of
The method 1000 may begin at 1002, where a plurality of flock configuration files corresponding to a plurality of services may be obtained. In some embodiments, the plurality of services being ones to be bootstrapped within a region during a region build process.
At 1004, an order by which the plurality of services are to be bootstrapped within the region may be determined based at least in part on the plurality of flock configuration files. For example, a static analysis of the plurality of clock configuration files can be performed to generated Build Dependency Graph 338 which identifies the order by which flock configs are to be released to bootstrap the plurality of services within the region.
At 1006, a first request related to bootstrapping a service of the plurality of services may be transmitted. The first request may include a flock configuration file corresponding to a first flock config. These operations may correspond to step 616 of
At 1008, planning data (e.g., planning data 620 of
At 1010, an identifier corresponding to a previously created resource of the cloud computing environment may be obtained (e.g., from the Resource Discovery Service 606 of
At 1012, the planning data may be modified to include the identifier corresponding to the previously created resource of the cloud computing environment. An example of modified planning data may include state data 810 of
At 1014, a second request related to bootstrapping the service may be transmitted (e.g., to CIOS Central 604). In some embodiments, the second request comprises the planning data including the identifier corresponding to the previously created resource. Transmitting the second request comprising the identifier may cause the service to be bootstrapped within the region using the previously created resource in the manner described in connection with
As noted above, infrastructure as a service (IaaS) is one particular type of cloud computing. IaaS can be configured to provide virtualized computing resources over a public network (e.g., the Internet). In an IaaS model, a cloud computing provider can host the infrastructure components (e.g., servers, storage devices, network nodes (e.g., hardware), deployment software, platform virtualization (e.g., a hypervisor layer), or the like). In some cases, an IaaS provider may also supply a variety of services to accompany those infrastructure components (e.g., billing, monitoring, logging, load balancing and clustering, etc.). Thus, as these services may be policy-driven, IaaS users may be able to implement policies to drive load balancing to maintain application availability and performance.
In some instances, IaaS customers may access resources and services through a wide area network (WAN), such as the Internet, and can use the cloud provider's services to install the remaining elements of an application stack. For example, the user can log in to the IaaS platform to create virtual machines (VMs), install operating systems (OSs) on each VM, deploy middleware such as databases, create storage buckets for workloads and backups, and even install enterprise software into that VM. Customers can then use the provider's services to perform various functions, including balancing network traffic, troubleshooting application issues, monitoring performance, managing disaster recovery, etc.
In most cases, a cloud computing model will require the participation of a cloud provider. The cloud provider may, but need not be, a third-party service that specializes in providing (e.g., offering, renting, selling) IaaS. An entity might also opt to deploy a private cloud, becoming its own provider of infrastructure services.
In some examples, IaaS deployment is the process of putting a new application, or a new version of an application, onto a prepared application server or the like. It may also include the process of preparing the server (e.g., installing libraries, daemons, etc.). This is often managed by the cloud provider, below the hypervisor layer (e.g., the servers, storage, network hardware, and virtualization). Thus, the customer may be responsible for handling (OS), middleware, and/or application deployment (e.g., on self-service virtual machines (e.g., that can be spun up on demand) or the like.
In some examples, IaaS provisioning may refer to acquiring computers or virtual hosts for use, and even installing needed libraries or services on them. In most cases, deployment does not include provisioning, and the provisioning may need to be performed first.
In some cases, there are two different challenges for IaaS provisioning. First, there is the initial challenge of provisioning the initial set of infrastructure before anything is running. Second, there is the challenge of evolving the existing infrastructure (e.g., adding new services, changing services, removing services, etc.) once everything has been provisioned. In some cases, these two challenges may be addressed by enabling the configuration of the infrastructure to be defined declaratively. In other words, the infrastructure (e.g., what components are needed and how they interact) can be defined by one or more configuration files. Thus, the overall topology of the infrastructure (e.g., what resources depend on which, and how they each work together) can be described declaratively. In some instances, once the topology is defined, a workflow can be generated that creates and/or manages the different components described in the configuration files.
In some examples, an infrastructure may have many interconnected elements. For example, there may be one or more virtual private clouds (VPCs) (e.g., a potentially on-demand pool of configurable and/or shared computing resources), also known as a core network. In some examples, there may also be one or more inbound/outbound traffic group rules provisioned to define how the inbound and/or outbound traffic of the network will be set up and one or more virtual machines (VMs). Other infrastructure elements may also be provisioned, such as a load balancer, a database, or the like. As more and more infrastructure elements are desired and/or added, the infrastructure may incrementally evolve.
In some instances, continuous deployment techniques may be employed to enable deployment of infrastructure code across various virtual computing environments. Additionally, the described techniques can enable infrastructure management within these environments. In some examples, service teams can write code that is desired to be deployed to one or more, but often many, different production environments (e.g., across various different geographic locations, sometimes spanning the entire world). However, in some examples, the infrastructure on which the code will be deployed must first be set up. In some instances, the provisioning can be done manually, a provisioning tool may be utilized to provision the resources, and/or deployment tools may be utilized to deploy the code once the infrastructure is provisioned.
The VCN 1106 can include a local peering gateway (LPG) 1110 that can be communicatively coupled to a secure shell (SSH) VCN 1112 via an LPG 1110 contained in the SSH VCN 1112. The SSH VCN 1112 can include an SSH subnet 1114, and the SSH VCN 1112 can be communicatively coupled to a control plane VCN 1116 via the LPG 1110 contained in the control plane VCN 1116. Also, the SSH VCN 1112 can be communicatively coupled to a data plane VCN 1118 via an LPG 1110. The control plane VCN 1116 and the data plane VCN 1118 can be contained in a service tenancy 1119 that can be owned and/or operated by the IaaS provider.
The control plane VCN 1116 can include a control plane demilitarized zone (DMZ) tier 1120 that acts as a perimeter network (e.g., portions of a corporate network between the corporate intranet and external networks). The DMZ-based servers may have restricted responsibilities and help keep breaches contained. Additionally, the DMZ tier 1120 can include one or more load balancer (LB) subnet(s) 1122, a control plane app tier 1124 that can include app subnet(s) 1126, a control plane data tier 1128 that can include database (DB) subnet(s) 1130 (e.g., frontend DB subnet(s) and/or backend DB subnet(s)). The LB subnet(s) 1122 contained in the control plane DMZ tier 1120 can be communicatively coupled to the app subnet(s) 1126 contained in the control plane app tier 1124 and an Internet gateway 1134 that can be contained in the control plane VCN 1116, and the app subnet(s) 1126 can be communicatively coupled to the DB subnet(s) 1130 contained in the control plane data tier 1128 and a service gateway 1136 and a network address translation (NAT) gateway 1138. The control plane VCN 1116 can include the service gateway 1136 and the NAT gateway 1138.
The control plane VCN 1116 can include a data plane mirror app tier 1140 that can include app subnet(s) 1126. The app subnet(s) 1126 contained in the data plane mirror app tier 1140 can include a virtual network interface controller (VNIC) 1142 that can execute a compute instance 1144. The compute instance 1144 can communicatively couple the app subnet(s) 1126 of the data plane mirror app tier 1140 to app subnet(s) 1126 that can be contained in a data plane app tier 1146.
The data plane VCN 1118 can include the data plane app tier 1146, a data plane DMZ tier 1148, and a data plane data tier 1150. The data plane DMZ tier 1148 can include LB subnet(s) 1122 that can be communicatively coupled to the app subnet(s) 1126 of the data plane app tier 1146 and the Internet gateway 1134 of the data plane VCN 1118. The app subnet(s) 1126 can be communicatively coupled to the service gateway 1136 of the data plane VCN 1118 and the NAT gateway 1138 of the data plane VCN 1118. The data plane data tier 1150 can also include the DB subnet(s) 1130 that can be communicatively coupled to the app subnet(s) 1126 of the data plane app tier 1146.
The Internet gateway 1134 of the control plane VCN 1116 and of the data plane VCN 1118 can be communicatively coupled to a metadata management service 1152 that can be communicatively coupled to public Internet 1154. Public Internet 1154 can be communicatively coupled to the NAT gateway 1138 of the control plane VCN 1116 and of the data plane VCN 1118. The service gateway 1136 of the control plane VCN 1116 and of the data plane VCN 1118 can be communicatively couple to cloud services 1156.
In some examples, the service gateway 1136 of the control plane VCN 1116 or of the data plane VCN 1118 can make application programming interface (API) calls to cloud services 1156 without going through public Internet 1154. The API calls to cloud services 1156 from the service gateway 1136 can be one-way: the service gateway 1136 can make API calls to cloud services 1156, and cloud services 1156 can send requested data to the service gateway 1136. But, cloud services 1156 may not initiate API calls to the service gateway 1136.
In some examples, the secure host tenancy 1104 can be directly connected to the service tenancy 1119, which may be otherwise isolated. The secure host subnet 1108 can communicate with the SSH subnet 1114 through an LPG 1110 that may enable two-way communication over an otherwise isolated system. Connecting the secure host subnet 1108 to the SSH subnet 1114 may give the secure host subnet 1108 access to other entities within the service tenancy 1119.
The control plane VCN 1116 may allow users of the service tenancy 1119 to set up or otherwise provision desired resources. Desired resources provisioned in the control plane VCN 1116 may be deployed or otherwise used in the data plane VCN 1118. In some examples, the control plane VCN 1116 can be isolated from the data plane VCN 1118, and the data plane mirror app tier 1140 of the control plane VCN 1116 can communicate with the data plane app tier 1146 of the data plane VCN 1118 via VNICs 1142 that can be contained in the data plane mirror app tier 1140 and the data plane app tier 1146.
In some examples, users of the system, or customers, can make requests, for example create, read, update, or delete (CRUD) operations, through public Internet 1154 that can communicate the requests to the metadata management service 1152. The metadata management service 1152 can communicate the request to the control plane VCN 1116 through the Internet gateway 1134. The request can be received by the LB subnet(s) 1122 contained in the control plane DMZ tier 1120. The LB subnet(s) 1122 may determine that the request is valid, and in response to this determination, the LB subnet(s) 1122 can transmit the request to app subnet(s) 1126 contained in the control plane app tier 1124. If the request is validated and requires a call to public Internet 1154, the call to public Internet 1154 may be transmitted to the NAT gateway 1138 that can make the call to public Internet 1154. Memory that may be desired to be stored by the request can be stored in the DB subnet(s) 1130.
In some examples, the data plane mirror app tier 1140 can facilitate direct communication between the control plane VCN 1116 and the data plane VCN 1118. For example, changes, updates, or other suitable modifications to configuration may be desired to be applied to the resources contained in the data plane VCN 1118. Via a VNIC 1142, the control plane VCN 1116 can directly communicate with, and can thereby execute the changes, updates, or other suitable modifications to configuration to, resources contained in the data plane VCN 1118.
In some embodiments, the control plane VCN 1116 and the data plane VCN 1118 can be contained in the service tenancy 1119. In this case, the user, or the customer, of the system may not own or operate either the control plane VCN 1116 or the data plane VCN 1118. Instead, the IaaS provider may own or operate the control plane VCN 1116 and the data plane VCN 1118, both of which may be contained in the service tenancy 1119. This embodiment can enable isolation of networks that may prevent users or customers from interacting with other users', or other customers', resources. Also, this embodiment may allow users or customers of the system to store databases privately without needing to rely on public Internet 1154, which may not have a desired level of threat prevention, for storage.
In other embodiments, the LB subnet(s) 1122 contained in the control plane VCN 1116 can be configured to receive a signal from the service gateway 1136. In this embodiment, the control plane VCN 1116 and the data plane VCN 1118 may be configured to be called by a customer of the IaaS provider without calling public Internet 1154. Customers of the IaaS provider may desire this embodiment since database(s) that the customers use may be controlled by the IaaS provider and may be stored on the service tenancy 1119, which may be isolated from public Internet 1154.
The control plane VCN 1216 can include a control plane DMZ tier 1220 (e.g., the control plane DMZ tier 1120 of
The control plane VCN 1216 can include a data plane mirror app tier 1240 (e.g., the data plane mirror app tier 1140 of
The Internet gateway 1234 contained in the control plane VCN 1216 can be communicatively coupled to a metadata management service 1252 (e.g., the metadata management service 1152 of
In some examples, the data plane VCN 1218 can be contained in the customer tenancy 1221. In this case, the IaaS provider may provide the control plane VCN 1216 for each customer, and the IaaS provider may, for each customer, set up a unique compute instance 1244 that is contained in the service tenancy 1219. Each compute instance 1244 may allow communication between the control plane VCN 1216, contained in the service tenancy 1219, and the data plane VCN 1218 that is contained in the customer tenancy 1221. The compute instance 1244 may allow resources, that are provisioned in the control plane VCN 1216 that is contained in the service tenancy 1219, to be deployed or otherwise used in the data plane VCN 1218 that is contained in the customer tenancy 1221.
In other examples, the customer of the IaaS provider may have databases that live in the customer tenancy 1221. In this example, the control plane VCN 1216 can include the data plane mirror app tier 1240 that can include app subnet(s) 1226. The data plane mirror app tier 1240 can reside in the data plane VCN 1218, but the data plane mirror app tier 1240 may not live in the data plane VCN 1218. That is, the data plane mirror app tier 1240 may have access to the customer tenancy 1221, but the data plane mirror app tier 1240 may not exist in the data plane VCN 1218 or be owned or operated by the customer of the IaaS provider. The data plane mirror app tier 1240 may be configured to make calls to the data plane VCN 1218 but may not be configured to make calls to any entity contained in the control plane VCN 1216. The customer may desire to deploy or otherwise use resources in the data plane VCN 1218 that are provisioned in the control plane VCN 1216, and the data plane mirror app tier 1240 can facilitate the desired deployment, or other usage of resources, of the customer.
In some embodiments, the customer of the IaaS provider can apply filters to the data plane VCN 1218. In this embodiment, the customer can determine what the data plane VCN 1218 can access, and the customer may restrict access to public Internet 1254 from the data plane VCN 1218. The IaaS provider may not be able to apply filters or otherwise control access of the data plane VCN 1218 to any outside networks or databases. Applying filters and controls by the customer onto the data plane VCN 1218, contained in the customer tenancy 1221, can help isolate the data plane VCN 1218 from other customers and from public Internet 1254.
In some embodiments, cloud services 1256 can be called by the service gateway 1236 to access services that may not exist on public Internet 1254, on the control plane VCN 1216, or on the data plane VCN 1218. The connection between cloud services 1256 and the control plane VCN 1216 or the data plane VCN 1218 may not be live or continuous. Cloud services 1256 may exist on a different network owned or operated by the IaaS provider. Cloud services 1256 may be configured to receive calls from the service gateway 1236 and may be configured to not receive calls from public Internet 1254. Some cloud services 1256 may be isolated from other cloud services 1256, and the control plane VCN 1216 may be isolated from cloud services 1256 that may not be in the same region as the control plane VCN 1216. For example, the control plane VCN 1216 may be located in “Region 1,” and cloud service “Deployment 11,” may be located in Region 1 and in “Region 2.” If a call to Deployment 11 is made by the service gateway 1236 contained in the control plane VCN 1216 located in Region 1, the call may be transmitted to Deployment 11 in Region 1. In this example, the control plane VCN 1216, or Deployment 11 in Region 1, may not be communicatively coupled to, or otherwise in communication with, Deployment 11 in Region 2.
The control plane VCN 1316 can include a control plane DMZ tier 1320 (e.g., the control plane DMZ tier 1120 of
The data plane VCN 1318 can include a data plane app tier 1346 (e.g., the data plane app tier 1146 of
The untrusted app subnet(s) 1362 can include one or more primary VNICs 1364(1)-(N) that can be communicatively coupled to tenant virtual machines (VMs) 1366(1)-(N). Each tenant VM 1366(1)-(N) can be communicatively coupled to a respective app subnet 1367(1)-(N) that can be contained in respective container egress VCNs 1368(1)-(N) that can be contained in respective customer tenancies 1370(1)-(N). Respective secondary VNICs 1372(1)-(N) can facilitate communication between the untrusted app subnet(s) 1362 contained in the data plane VCN 1318 and the app subnet contained in the container egress VCNs 1368(1)-(N). Each container egress VCNs 1368(1)-(N) can include a NAT gateway 1338 that can be communicatively coupled to public Internet 1354 (e.g., public Internet 1154 of
The Internet gateway 1334 contained in the control plane VCN 1316 and contained in the data plane VCN 1318 can be communicatively coupled to a metadata management service 1352 (e.g., the metadata management system 1152 of
In some embodiments, the data plane VCN 1318 can be integrated with customer tenancies 1370. This integration can be useful or desirable for customers of the IaaS provider in some cases such as a case that may desire support when executing code. The customer may provide code to run that may be destructive, may communicate with other customer resources, or may otherwise cause undesirable effects. In response to this, the IaaS provider may determine whether to run code given to the IaaS provider by the customer.
In some examples, the customer of the IaaS provider may grant temporary network access to the IaaS provider and request a function to be attached to the data plane app tier 1346. Code to run the function may be executed in the VMs 1366(1)-(N), and the code may not be configured to run anywhere else on the data plane VCN 1318. Each VM 1366(1)-(N) may be connected to one customer tenancy 1370. Respective containers 1371(1)-(N) contained in the VMs 1366(1)-(N) may be configured to run the code. In this case, there can be a dual isolation (e.g., the containers 1371(1)-(N) running code, where the containers 1371(1)-(N) may be contained in at least the VM 1366(1)-(N) that are contained in the untrusted app subnet(s) 1362), which may help prevent incorrect or otherwise undesirable code from damaging the network of the IaaS provider or from damaging a network of a different customer. The containers 1371(1)-(N) may be communicatively coupled to the customer tenancy 1370 and may be configured to transmit or receive data from the customer tenancy 1370. The containers 1371(1)-(N) may not be configured to transmit or receive data from any other entity in the data plane VCN 1318. Upon completion of running the code, the IaaS provider may kill or otherwise dispose of the containers 1371(1)-(N).
In some embodiments, the trusted app subnet(s) 1360 may run code that may be owned or operated by the IaaS provider. In this embodiment, the trusted app subnet(s) 1360 may be communicatively coupled to the DB subnet(s) 1330 and be configured to execute CRUD operations in the DB subnet(s) 1330. The untrusted app subnet(s) 1362 may be communicatively coupled to the DB subnet(s) 1330, but in this embodiment, the untrusted app subnet(s) may be configured to execute read operations in the DB subnet(s) 1330. The containers 1371(1)-(N) that can be contained in the VM 1366(1)-(N) of each customer and that may run code from the customer may not be communicatively coupled with the DB subnet(s) 1330.
In other embodiments, the control plane VCN 1316 and the data plane VCN 1318 may not be directly communicatively coupled. In this embodiment, there may be no direct communication between the control plane VCN 1316 and the data plane VCN 1318. However, communication can occur indirectly through at least one method. An LPG 1310 may be established by the IaaS provider that can facilitate communication between the control plane VCN 1316 and the data plane VCN 1318. In another example, the control plane VCN 1316 or the data plane VCN 1318 can make a call to cloud services 1356 via the service gateway 1336. For example, a call to cloud services 1356 from the control plane VCN 1316 can include a request for a service that can communicate with the data plane VCN 1318.
The control plane VCN 1416 can include a control plane DMZ tier 1420 (e.g., the control plane DMZ tier 1120 of
The data plane VCN 1418 can include a data plane app tier 1446 (e.g., the data plane app tier 1146 of
The untrusted app subnet(s) 1462 can include primary VNICs 1464(1)-(N) that can be communicatively coupled to tenant virtual machines (VMs) 1466(1)-(N) residing within the untrusted app subnet(s) 1462. Each tenant VM 1466(1)-(N) can run code in a respective container 1467(1)-(N), and be communicatively coupled to an app subnet 1426 that can be contained in a data plane app tier 1446 that can be contained in a container egress VCN 1468. Respective secondary VNICs 1472(1)-(N) can facilitate communication between the untrusted app subnet(s) 1462 contained in the data plane VCN 1418 and the app subnet contained in the container egress VCN 1468. The container egress VCN can include a NAT gateway 1438 that can be communicatively coupled to public Internet 1454 (e.g., public Internet 1154 of
The Internet gateway 1434 contained in the control plane VCN 1416 and contained in the data plane VCN 1418 can be communicatively coupled to a metadata management service 1452 (e.g., the metadata management system 1152 of
VCN 1418. The service gateway 1436 contained in the control plane VCN 1416 and contained in the data plane VCN 1418 can be communicatively couple to cloud services 1456.
In some examples, the pattern illustrated by the architecture of block diagram 1400 of
In other examples, the customer can use the containers 1467(1)-(N) to call cloud services 1456. In this example, the customer may run code in the containers 1467(1)-(N) that requests a service from cloud services 1456. The containers 1467(1)-(N) can transmit this request to the secondary VNICs 1472(1)-(N) that can transmit the request to the NAT gateway that can transmit the request to public Internet 1454. Public Internet 1454 can transmit the request to LB subnet(s) 1422 contained in the control plane VCN 1416 via the Internet gateway 1434. In response to determining the request is valid, the LB subnet(s) can transmit the request to app subnet(s) 1426 that can transmit the request to cloud services 1456 via the service gateway 1436.
