In the following description, various embodiments will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the embodiments may be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described.
Computing systems can be configured to collect explicit feedback from users regarding a product or a service. However, these computing systems come with high upfront investment costs and have practical problems. For example, online surveys can generate thousands of responses, but each response needs to be evaluated to determine the value of the response. Additionally, programming the computing system to distinguish between a constructive response and an unconstructive response is a tedious and time-consuming activity. These computing systems also have practical problems that diminish the quality of the explicit feedback. For example, many online recommendation systems ask a user to provide an annotation describing the quality of a recommended product or service. In many instances, the request for the annotation is made after the user has left the recommendation page, and the user is unlikely to return to the page.
Embodiments of the present disclosure provide techniques for a consumer-defined cloud-based implicit feedback service. The implicit feedback service can be a service offered by a cloud services provider. To initiate the service, an attribution server of the implicit feedback service can receive a data schema from a customer of a cloud computing environment. The data schema can provide a formal definition of an event data instance and one or more basis for relating one more event data instance. The data schema can include, for example, a customer ID, a request ID, and a device ID. The attribution server can transmit the data schema to one or more event recorders executing on one or more third-party web servers. The one or more event recorders can transmit a recorded event back to the attribution server. Based on the data schema, the attribution server can identify the event as an initial event. The initial event can be, for example, a customer requesting an instance of an application through the web server. The attribution server can further receive one or more events related to the initial event from the event recorders. The attribution server can normalize each event instance based on the data schema. Normalization refers to marking metadata or adding metadata to the event to identify the event as related to the initial event. The attribution server can then link the connected events together based on the normalization. The attribution server can then generate an attribution score between events that describes how likely one event followed another event.
As a practical example, a data scientist can access laboratory notebook software to initialize an electronic notebook for a project. The notebook can include an identity of a principal investigator (PI), co-investigator, source of grant funds, laboratory, and other related information. The attribution server can have received a data schema from the notebook provider (e.g., customer) that identifies the initialization of the notebook as the initial event. One or more co-investigators can, at a later time, publish a web-based article on a system that is separate from the laboratory notebook software. The name of the co-inventors can be detected by an event recorder as related to the initial event. The attribution server can receive the event from an event recorder. The attribution server can convert both the initial event and the subsequent event to a common format based on the data schema. The attribution server can then apply customer-defined criteria to calculate an attribution score between the two events.

The console 102 can be in operable communication with a web server 104. The web server 104 can be in one or more data center environments. The web server 104 can be connected to the cloud infrastructure (CI) system 106, or the web server 104 can be connected to a third-party cloud infrastructure system. The web server 104 can include a computing device (e.g., a server or series of computing devices). The web server 104 can be configured to perform various processing tasks to implement one or more application services. The web server 104 can include a client application such as an event recorder that monitors data traffic to and from the web server 104. The event recorder can receive a data schema and record event data instances based on the schema. The event recorder can further transmit the event data instances to the CI system 106.
The CI system 106 can include one or more interconnected computing devices implementing one or more cloud computing applications or services. For example, the CI system 106 can store and provide access to database data (e.g., via a query of the database). The computing devices 108a-c included in the CI system 106 can be in one or more data center environments (e.g., colocation centers). The computing device 108a can include a computing device (e.g., a server or series of computing devices) of the CI system 106. For example, the computing device 108a can include a server that is connected to the cloud infrastructure system 106 at a data center environment (e.g., a colocation center). The computing device 108a can be configured to perform various processing tasks to implement one or more application services. For example, the computing device 108a can be configured to receive event data instances from one or more client applications executing on one or more web servers. The computing device 108a can further be configured to normalize each event data instance to conform the format of the event data instances to a uniform format. The computing device 108a can further use a set of customer-defined criteria to calculate an attribution score between events.

An event recorder 202 can be stored on the web server 210. The event recorder 202 monitors web data traffic and filters out event data instances based on a data schema. For example, the event recorder 202 can read all outgoing HTTP requests from the web server 210 and incoming HTTP responses to the web server 210 to filter out events based on the data schema. The event recorder 202 is operable to store events having different mediums. For example, the event recorder 202 can record events such as at rest object, or live streaming data. The data schema, such as an XML schema—can provide fields to identify particular data traffic characteristics for filtering out event data instances. For example, one of the fields can include a code indicating the HTTP request is a request to initialize a new laboratory notebook instance.
An event recorder does not need to be associated with a single web server. Each event recorder 202, 204, 206, and 208 can have a copy of the data schema and can be associated with a different web server 210, 212, 214, and 216. For example, at T1, the event recorder 204 can monitor a co-principal investigator data contacting a machine learning services platform service. The machine learning platform service can be made available via a web server 212, which is not necessarily the same as the electronic notebook web server 210. The event recorder 204 can still record the event and send the recorded event to the attribution server 218. It should be appreciated that although

For example, at T0, an initial event can be an email from an IT department requesting that each member install a specific software. The attribution generator 310 can mine the email and detect the name of the software. The attribution generator 310 can include the software name as a keyword in a column or row of keywords. The attribution generator 310 can also mine subsequent events for related information, such as an installation wizard instance for the software on an email recipient's computing device at T1. The attribution generator 310 can also include the name of the software as an entry in a data table describing the installation wizard event. In some embodiments, the criteria for linking events are configurable by the customer.
The attribution generator 310 can further link one event to an attributed event to create an attributed record. For example, the attribution generator 310 can link the installation wizard event to the email event. The link can be one or more data structures that join one or more events. In some embodiments, the link is created by adding a data field to the email event and/or the installation event. The attribution generator 310 further writes a pointer to the data field that points from the address storing the installation wizard event to an address storing the email event or vice versa. The events are not necessarily stored contiguously in physical memory; therefore, joining two or more events creates a linked list (e.g., the attributed record) in the collection of events representing a sequence of events.
The attribution generator 310 can transmit the linked events as an attributed record to a memory queue 312. The memory queue 312 can be a linear data structure that stores the attributed records and persists in memory. The memory queue 312 can operate on a first-in-first-out basis, and attributed records that are inserted into the memory queue 312 first will leave the memory queue 312 first. The memory queue 312 can transmit the oldest attributed record to an attribution unit 314.
The attribution unit 314 can generate a respective score between each event and each other event. For example, if the attributed record included a first event at T0, a second event at T1, and a third event at T2, the attribution unit 314 generates three scores. The attribution unit 314 can create a first score between the first event and second event, a second score between the first event and the third event, and a third score between the second event and the third event. The attribution unit 314 can generate attribution scores based on pre-configured scoring templates. These pre-configured scoring templates can be modified or customized by a customer. As an example, a customer can provide a scoring template that can assign higher scores to events based on a temporal proximity to an initial event. In other words, events that are closer in time can be scored higher than events that are farther away in time (e.g., ScoreT_initial=1/log(T1−Tinitial) 1/log(T2−Tinitial)+ . . . ). In other instances, a customer can provide a different scoring scheme.
As an example, an initial event can be an email transmitted to a recipient, and another event is a near immediate reply to the email. The score attributed to the relationship between events indicates that the reply email is likely attributed to the initial email based on the immediateness of the response and the direct response to the email. In another example, an initial event can also be an email sent to a recipient and the email describes an automobile. A second event can be the recipient looking up the automobile through a web browser a few weeks after the initial email. In this case, based on the time elapsed between the initial email and the web search, and the search not being a response to the email, the likelihood that the email was followed by the automobile search is not as likely as in the first example.
In some embodiments, the output of the attribution unit 314 can be used as a private data set for training a machine learning algorithm. In these embodiments, the attribution unit 314 can further prepare the scoring output to be consumable by a machine learning algorithm. The attribution unit 314 can identify mistakes and errors in the data. To clean the data, the attribution unit 314 can apply statistical techniques to detect anomalies and contradictions in the scoring and event data instances. Examples of anomalies and contradictions include missing values, outliers, duplicated data, and sparse classes. In some embodiments, the attribution unit 314 can then correct or remove any of the anomalies and contradictions. In embodiments that the attribution unit 314 corrects or removes the data, the attribution unit 314 can then engage in feature selection to identify potential inputs and feature relationships that are most relevant to a customer's task. After identifying the relevant features and relationships, the attribution unit 314 can transform the data to be appropriate for generating predictions. For example, the attribution unit 314 can convert any categorical variables to numerical representations. The attribution unit 314 can normalize skewed data, especially if the machine learning algorithm uses regression algorithms or is being executed on a neural network.
In other embodiments, the objective of the machine learning algorithm can include identifying fraudulent user activity. In these embodiments, the output of the attribution unit 314 can be used as inputs for the machine learning algorithm without initially cleaning the data. The machine learning algorithm can be configured to determine whether any of the anomalies and/or contradictions are indicative of fraudulent activity. If the machine learning algorithm determines that the anomalies and/or contradictions are indicative of fraudulent activity, the attribution unit 314 can issue an alert to a customer for appropriate action. If the machine learning algorithm determines that the anomalies and/or contradictions are not indicative of fraudulent activity, the attribution unit 314 can proceed to clean the data.
A certificate authority 318 can create a signed certificate, such as through a public key, for the event recorder 302. The certificate authority 318 can further create a signed certificate, such as a through private key, for the attribution server 308. The event recorder 302 and the attribution server 308 can securely communicate using the signed certificated. The certificate authority 318 can be, for example, a cloud services provider (CSP) offering the CI system 106 to a customer. A customer of the implicit feedback service can communicate with the attribution server 308 through an application programming interface (API). The customer can initiate an API call to request the attributed record and calculated scores. The API call can include a call type, a request URL, a request header including an authentication token, and a request body. In response, the attribution server 308 can access a database and retrieve the requested attributed record and scores. The attribution server 308 can then transmit the requested attributed record and scores to the customer.

Once the attribution generator 414 receives the event data instances, an attribution process 412 can begin. The attribution generator 414 can further link the first event data instance 402 to the second event data instance 404, to the third event data instance 406, and to the fourth event data instance 408 to create an attributed record 416. The link can be one or more data structures that join one or more event data instances. In some embodiments, the link is created by adding a pointer to each event, where the pointer points to the next event data of the attributed record 416. As seen in

At 502, an attribution server can transmit a data schema to a set of event recorders. The attribution server can execute on a computing device of a cloud infrastructure system. The event recorders can execute on a web server. The data schema can provide a formal definition of an event data instance and one or more basis for relating one more event data instance. The data schema can include, for example, a customer ID, a request ID, and a device ID.
At 504, the attribution generator receives event data instances from the event recorders. The event data instances include multiple events recorded by the event recorders. The event data instances can be received individually over a period of time, or multiple events can be received as a batch from an event recorder. It should be appreciated that the event recorders transmit the event data without any knowledge of whether the described events are related. At this point, an event recorder records an event data instance because the instance includes some criteria found in the data schema.
At 506, the attribution generator determines which event data instances should be linked together based on criteria found in the data schema. Once the attribution generator determines which events are related, the attribution generator can format the event data instances to a uniform format at 508. The event data can be collected by one or more event recorders. The event recorders can execute on web servers that may be running one or more applications. Therefore, the event recorders are not necessarily recording data traffic originating or being received from a same application. Therefore, the attribution generator converts the event data instances to be in a uniform format. In some embodiments, the data schema includes a preferred format of the customer. In other embodiments, the attribution generator can select a default format.
At 510, the attribution generator can link the related event data instances together. In some embodiments, the attribution server links the related event data instances together by adding a pointer that points from one event data instance to another event data instance. The linked event data instances can form an attributed record that can be transmitted to an attribution unit.
At 512, the attribution unit can calculate an attribution score between each related event data instance. The attribution score describes the degree to which one event is attributed to another event. In other words, the attribution score between two event data instances describes the likelihood that one event data instance followed the other event data instance.
At 514, the attribution server can receive an application programming interface (API) call from a third party for the attributed record and the calculated attribution scores. At 516, the attribution server transmits the attributed records and calculated attribution scores to the third party.
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 may first need to 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 606 can include a local peering gateway (LPG) 610 that can be communicatively coupled to a secure shell (SSH) VCN 612 via an LPG 610 contained in the SSH VCN 612. The SSH VCN 612 can include an SSH subnet 614, and the SSH VCN 612 can be communicatively coupled to a control plane VCN 616 via the LPG 610 contained in the control plane VCN 616. Also, the SSH VCN 612 can be communicatively coupled to a data plane VCN 618 via an LPG 610. The control plane VCN 616 and the data plane VCN 618 can be contained in a service tenancy 619 that can be owned and/or operated by the IaaS provider.
The control plane VCN 616 can include a control plane demilitarized zone (DMZ) tier 620 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 620 can include one or more load balancer (LB) subnet(s) 622, a control plane app tier 624 that can include app subnet(s) 626, a control plane data tier 628 that can include database (DB) subnet(s) 630 (e.g., frontend DB subnet(s) and/or backend DB subnet(s)). The LB subnet(s) 622 contained in the control plane DMZ tier 620 can be communicatively coupled to the app subnet(s) 626 contained in the control plane app tier 624 and an Internet gateway 634 that can be contained in the control plane VCN 616, and the app subnet(s) 626 can be communicatively coupled to the DB subnet(s) 630 contained in the control plane data tier 628 and a service gateway 636 and a network address translation (NAT) gateway 638. The control plane VCN 616 can include the service gateway 636 and the NAT gateway 638.
The control plane VCN 616 can include a data plane mirror app tier 640 that can include app subnet(s) 626. The app subnet(s) 626 contained in the data plane mirror app tier 640 can include a virtual network interface controller (VNIC) 642 that can execute a compute instance 644. The compute instance 644 can communicatively couple the app subnet(s) 626 of the data plane mirror app tier 640 to app subnet(s) 626 that can be contained in a data plane app tier 646.
The data plane VCN 618 can include the data plane app tier 646, a data plane DMZ tier 648, and a data plane data tier 650. The data plane DMZ tier 648 can include LB subnet(s) 622 that can be communicatively coupled to the app subnet(s) 626 of the data plane app tier 646 and the Internet gateway 634 of the data plane VCN 618. The app subnet(s) 626 can be communicatively coupled to the service gateway 636 of the data plane VCN 618 and the NAT gateway 638 of the data plane VCN 618. The data plane data tier 650 can also include the DB subnet(s) 630 that can be communicatively coupled to the app subnet(s) 626 of the data plane app tier 646.
The Internet gateway 634 of the control plane VCN 616 and of the data plane VCN 618 can be communicatively coupled to a metadata management service 652 that can be communicatively coupled to public Internet 654. Public Internet 654 can be communicatively coupled to the NAT gateway 638 of the control plane VCN 616 and of the data plane VCN 618. The service gateway 636 of the control plane VCN 616 and of the data plane VCN 618 can be communicatively couple to cloud services 656.
In some examples, the service gateway 636 of the control plane VCN 616 or of the data plane VCN 618 can make application programming interface (API) calls to cloud services 656 without going through public Internet 654. The API calls to cloud services 656 from the service gateway 636 can be one-way: the service gateway 636 can make API calls to cloud services 656, and cloud services 656 can send requested data to the service gateway 636. But, cloud services 656 may not initiate API calls to the service gateway 636.
In some examples, the secure host tenancy 604 can be directly connected to the service tenancy 619, which may be otherwise isolated. The secure host subnet 608 can communicate with the SSH subnet 614 through an LPG 610 that may enable two-way communication over an otherwise isolated system. Connecting the secure host subnet 608 to the SSH subnet 614 may give the secure host subnet 608 access to other entities within the service tenancy 619.
The control plane VCN 616 may allow users of the service tenancy 619 to set up or otherwise provision desired resources. Desired resources provisioned in the control plane VCN 616 may be deployed or otherwise used in the data plane VCN 618. In some examples, the control plane VCN 616 can be isolated from the data plane VCN 618, and the data plane mirror app tier 640 of the control plane VCN 616 can communicate with the data plane app tier 646 of the data plane VCN 618 via VNICs 642 that can be contained in the data plane mirror app tier 640 and the data plane app tier 646.
In some examples, users of the system, or customers, can make requests, for example create, read, update, or delete (CRUD) operations, through public Internet 654 that can communicate the requests to the metadata management service 652. The metadata management service 652 can communicate the request to the control plane VCN 616 through the Internet gateway 634. The request can be received by the LB subnet(s) 622 contained in the control plane DMZ tier 620. The LB subnet(s) 622 may determine that the request is valid, and in response to this determination, the LB subnet(s) 622 can transmit the request to app subnet(s) 626 contained in the control plane app tier 624. If the request is validated and requires a call to public Internet 654, the call to public Internet 654 may be transmitted to the NAT gateway 638 that can make the call to public Internet 654. Memory that may be desired to be stored by the request can be stored in the DB subnet(s) 630.
In some examples, the data plane mirror app tier 640 can facilitate direct communication between the control plane VCN 616 and the data plane VCN 618. 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 618. Via a VNIC 642, the control plane VCN 616 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 618.
In some embodiments, the control plane VCN 616 and the data plane VCN 618 can be contained in the service tenancy 619. In this case, the user, or the customer, of the system may not own or operate either the control plane VCN 616 or the data plane VCN 618. Instead, the IaaS provider may own or operate the control plane VCN 616 and the data plane VCN 618, both of which may be contained in the service tenancy 619. 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 654, which may not have a desired level of threat prevention, for storage.
In other embodiments, the LB subnet(s) 622 contained in the control plane VCN 616 can be configured to receive a signal from the service gateway 636. In this embodiment, the control plane VCN 616 and the data plane VCN 618 may be configured to be called by a customer of the IaaS provider without calling public Internet 654. 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 619, which may be isolated from public Internet 654.
The control plane VCN 716 can include a control plane DMZ tier 720 (e.g., the control plane DMZ tier 620 of
The control plane VCN 716 can include a data plane mirror app tier 740 (e.g., the data plane mirror app tier 640 of
The Internet gateway 734 contained in the control plane VCN 716 can be communicatively coupled to a metadata management service 752 (e.g., the metadata management service 652 of
In some examples, the data plane VCN 718 can be contained in the customer tenancy 221. In this case, the IaaS provider may provide the control plane VCN 716 for each customer, and the IaaS provider may, for each customer, set up a unique compute instance 744 that is contained in the service tenancy 719. Each compute instance 744 may allow communication between the control plane VCN 716, contained in the service tenancy 719, and the data plane VCN 718 that is contained in the customer tenancy 721. The compute instance 744 may allow resources, that are provisioned in the control plane VCN 716 that is contained in the service tenancy 719, to be deployed or otherwise used in the data plane VCN 718 that is contained in the customer tenancy 721.
In other examples, the customer of the IaaS provider may have databases that live in the customer tenancy 721. In this example, the control plane VCN 716 can include the data plane mirror app tier 740 that can include app subnet(s) 726. The data plane mirror app tier 740 can reside in the data plane VCN 718, but the data plane mirror app tier 740 may not live in the data plane VCN 718. That is, the data plane mirror app tier 740 may have access to the customer tenancy 721, but the data plane mirror app tier 740 may not exist in the data plane VCN 718 or be owned or operated by the customer of the IaaS provider. The data plane mirror app tier 740 may be configured to make calls to the data plane VCN 718 but may not be configured to make calls to any entity contained in the control plane VCN 716. The customer may desire to deploy or otherwise use resources in the data plane VCN 718 that are provisioned in the control plane VCN 716, and the data plane mirror app tier 740 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 718. In this embodiment, the customer can determine what the data plane VCN 718 can access, and the customer may restrict access to public Internet 754 from the data plane VCN 718. The IaaS provider may not be able to apply filters or otherwise control access of the data plane VCN 718 to any outside networks or databases. Applying filters and controls by the customer onto the data plane VCN 718, contained in the customer tenancy 721, can help isolate the data plane VCN 718 from other customers and from public Internet 754.
In some embodiments, cloud services 756 can be called by the service gateway 736 to access services that may not exist on public Internet 754, on the control plane VCN 716, or on the data plane VCN 718. The connection between cloud services 756 and the control plane VCN 716 or the data plane VCN 718 may not be live or continuous. Cloud services 756 may exist on a different network owned or operated by the IaaS provider. Cloud services 756 may be configured to receive calls from the service gateway 736 and may be configured to not receive calls from public Internet 754. Some cloud services 756 may be isolated from other cloud services 756, and the control plane VCN 716 may be isolated from cloud services 756 that may not be in the same region as the control plane VCN 716. For example, the control plane VCN 716 may be located in “Region 1,” and cloud service “Deployment 1,” may be located in Region 1 and in “Region 2.” If a call to Deployment 1 is made by the service gateway 736 contained in the control plane VCN 716 located in Region 1, the call may be transmitted to Deployment 1 in Region 1. In this example, the control plane VCN 716, or Deployment 1 in Region 1, may not be communicatively coupled to, or otherwise in communication with, Deployment 1 in Region 2.
The control plane VCN 816 can include a control plane DMZ tier 820 (e.g., the control plane DMZ tier 620 of
The data plane VCN 818 can include a data plane app tier 846 (e.g., the data plane app tier 646 of
The untrusted app subnet(s) 862 can include one or more primary VNICs 864(1)-(N) that can be communicatively coupled to tenant virtual machines (VMs) 866(1)-(N). Each tenant VM 866(1)-(N) can be communicatively coupled to a respective app subnet 867(1)-(N) that can be contained in respective container egress VCNs 868(1)-(N) that can be contained in respective customer tenancies 870(1)-(N). Respective secondary VNICs 872(1)-(N) can facilitate communication between the untrusted app subnet(s) 862 contained in the data plane VCN 818 and the app subnet contained in the container egress VCNs 868(1)-(N). Each container egress VCNs 868(1)-(N) can include a NAT gateway 838 that can be communicatively coupled to public Internet 854 (e.g., public Internet 654 of
In some embodiments, the data plane VCN 818 can be integrated with customer tenancies 870. 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 846. Code to run the function may be executed in the VMs 866(1)-(N), and the code may not be configured to run anywhere else on the data plane VCN 818. Each VM 866(1)-(N) may be connected to one customer tenancy 870. Respective containers 871(1)-(N) contained in the VMs 866(1)-(N) may be configured to run the code. In this case, there can be a dual isolation (e.g., the containers 871(1)-(N) running code, where the containers 871(1)-(N) may be contained in at least the VM 866(1)-(N) that are contained in the untrusted app subnet(s) 862), 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 871(1)-(N) may be communicatively coupled to the customer tenancy 870 and may be configured to transmit or receive data from the customer tenancy 870. The containers 871(1)-(N) may not be configured to transmit or receive data from any other entity in the data plane VCN 818. Upon completion of running the code, the IaaS provider may kill or otherwise dispose of the containers 871(1)-(N).
In some embodiments, the trusted app subnet(s) 860 may run code that may be owned or operated by the IaaS provider. In this embodiment, the trusted app subnet(s) 860 may be communicatively coupled to the DB subnet(s) 830 and be configured to execute CRUD operations in the DB subnet(s) 830. The untrusted app subnet(s) 862 may be communicatively coupled to the DB subnet(s) 830, but in this embodiment, the untrusted app subnet(s) may be configured to execute read operations in the DB subnet(s) 830. The containers 871(1)-(N) that can be contained in the VM 866(1)-(N) of each customer and that may run code from the customer may not be communicatively coupled with the DB subnet(s) 830.
In other embodiments, the control plane VCN 816 and the data plane VCN 818 may not be directly communicatively coupled. In this embodiment, there may be no direct communication between the control plane VCN 816 and the data plane VCN 818. However, communication can occur indirectly through at least one method. An LPG 810 may be established by the IaaS provider that can facilitate communication between the control plane VCN 816 and the data plane VCN 818. In another example, the control plane VCN 816 or the data plane VCN 818 can make a call to cloud services 856 via the service gateway 836. For example, a call to cloud services 856 from the control plane VCN 816 can include a request for a service that can communicate with the data plane VCN 818.
The control plane VCN 916 can include a control plane DMZ tier 920 (e.g., the control plane DMZ tier 620 of
The data plane VCN 918 can include a data plane app tier 946 (e.g., the data plane app tier 646 of
The untrusted app subnet(s) 962 can include primary VNICs 964(1)-(N) that can be communicatively coupled to tenant virtual machines (VMs) 966(1)-(N) residing within the untrusted app subnet(s) 962. Each tenant VM 966(1)-(N) can run code in a respective container 967(1)-(N), and be communicatively coupled to an app subnet 926 that can be contained in a data plane app tier 946 that can be contained in a container egress VCN 968. Respective secondary VNICs 972(1)-(N) can facilitate communication between the untrusted app subnet(s) 962 contained in the data plane VCN 918 and the app subnet contained in the container egress VCN 968. The container egress VCN can include a NAT gateway 938 that can be communicatively coupled to public Internet 954 (e.g., public Internet 654 of
The Internet gateway 934 contained in the control plane VCN 916 and contained in the data plane VCN 918 can be communicatively coupled to a metadata management service 952 (e.g., the metadata management system 652 of
In some examples, the pattern illustrated by the architecture of block diagram 900 of
In other examples, the customer can use the containers 967(1)-(N) to call cloud services 956. In this example, the customer may run code in the containers 967(1)-(N) that requests a service from cloud services 956. The containers 967(1)-(N) can transmit this request to the secondary VNICs 972(1)-(N) that can transmit the request to the NAT gateway that can transmit the request to public Internet 954. Public Internet 954 can transmit the request to LB subnet(s) 922 contained in the control plane VCN 916 via the Internet gateway 934. In response to determining the request is valid, the LB subnet(s) can transmit the request to app subnet(s) 926 that can transmit the request to cloud services 956 via the service gateway 936.
