The field relates generally to information processing, and more particularly to deploying virtual machines in information processing systems.
Information processing systems increasingly utilize virtual resources to meet changing user needs in an efficient, flexible and cost-effective manner. For example, cloud computing systems implemented using virtual resources such as virtual machines have been widely adopted. Such virtual resources may be used to provide at least a portion of the virtualization infrastructure of a given information processing system. However, significant challenges can arise in the deployment of virtual machines to a virtualization platform.
Illustrative embodiments of the present disclosure provide techniques for deploying virtual machines to a virtualization management environment using an agent component to obtain remote virtual machine templates.
In one embodiment, a method comprises, in response to receiving, by an agent component executing in a virtualization management server, a request to deploy a virtual machine and a storage location of a template for the virtual machine, the agent component performing the following steps: obtaining the template for the virtual machine from one or more of an orchestration engine and a remote data source identified by the storage location; and replicating the obtained template for the virtual machine to create the virtual machine.
In some embodiments, the request to deploy the virtual machine further comprises deployment information used to configure the virtual machine. For example, the deployment information may comprise an identifier of the template for the virtual machine and/or a name of the virtual machine. The replicating of the obtained template for the virtual machine to create the virtual machine may also comprise processing at least some of the deployment information to configure the virtual machine.
In one or more embodiments, the method further comprises, by the agent component, monitoring an execution of the created virtual machine and evaluating one or more policies provided by the orchestration engine with respect to one or more of (i) security controls for the created virtual machine and (ii) network requirements associated with the created virtual machine. The agent component may initiate one or more automated remedial actions in response to a detection of a violation of one or more of the policies.
These and other illustrative embodiments include, without limitation, methods, apparatus, networks, systems and processor-readable storage media.
Illustrative embodiments will be described herein with reference to exemplary information processing systems and associated computers, servers, storage devices and other processing devices. It is to be appreciated, however, that embodiments are not restricted to use with the particular illustrative system and device configurations shown. Accordingly, the term “information processing system” as used herein is intended to be broadly construed, so as to encompass, for example, processing systems comprising cloud computing and storage systems, as well as other types of processing systems comprising various combinations of physical and virtual processing resources. An information processing system may therefore comprise, for example, at least one data center or other type of cloud-based system that includes one or more clouds hosting tenants that access cloud resources.
A virtualization platform enables customers to execute virtual machines. Automation systems, such as orchestration engines, often seek to deploy workloads to the virtualization platform. Such automation systems, however, often lack an ability to monitor the virtual machine execution in order to enforce applicable policies, such as policies related to security controls (e.g., unauthorized intrusion/access of a virtual machine or other anomalous behavior) and network requirements associated with a deployed virtual machine. In addition, there is often a rigorous set of prerequisites that ensure that the needed components are in place to allow such deployments to succeed.
An orchestration engine often needs to deploy workloads to an external compute platform, such as a virtualization platform. In one or more embodiments, an orchestration engine deploys virtual machines to a virtualization platform using an agent component to obtain one or more needed virtual machine templates that are not available to the virtualization platform at the time of deployment. The disclosed agent component executes in the virtualization platform environment and serves as a conduit between the orchestration engine and the virtualization platform. The agent component may comprise a software agent and is sometimes referred to herein in some embodiments as an agent executing in a virtualization management server.
In one or more embodiments, the disclosed agent component for virtual machine deployment to a virtualization platform can obtain a template for a deployed virtual machine (e.g., that is not already in the inventory of the virtualization platform) from the orchestration engine or from a network-accessible location identified by the orchestration engine, or determined by the agent component, when needed. The disclosed agent component may also cache the obtained template and/or upload the obtained template into the inventory of the virtualization platform. The disclosed agent component may monitor the deployed virtual machine using a persistent connection to detect, for example, intrusions and/or anomalous behavior. The disclosed agent component may initiate one or more automated remedial actions upon detection of an intrusion and/or anomalous behavior, such as sending an alert and/or suspending operations of the deployed virtual machine.
In some embodiments, the disclosed agent component may obtain the applicable policies from the orchestration engine, an information technology professional and/or a customer. Thereafter, in at least some embodiments, the disclosed agent component may work autonomously to monitor the deployed virtual machine to mitigate any policy violations, such as a large geographic separation, a high network latency, and/or intermittent disconnections.
The host devices 102, orchestration engine 112 and/or virtualization platform 122 illustratively comprise respective computers, servers or other types of processing devices capable of communicating with one another via the network 108. For example, at least a subset of the host devices 102 may be implemented as respective virtual machines of a compute services platform or other type of processing platform. The host devices 102 in such an arrangement illustratively provide compute services such as execution of one or more applications on behalf of each of one or more users associated with respective ones of the host devices 102.
The term “user” herein is intended to be broadly construed so as to encompass numerous arrangements of human, hardware, software or firmware entities, as well as combinations of such entities.
Compute and/or storage services may be provided for users under a Platform-as-a-Service (PaaS) model, a Storage-as-a-Service (STaaS) model, an Infrastructure-as-a-Service (IaaS) model and/or a Function-as-a-Service (FaaS) model, although it is to be appreciated that numerous other cloud infrastructure arrangements could be used. Also, illustrative embodiments can be at least partially implemented outside of the cloud infrastructure context, as in the case of a stand-alone computing and storage system implemented within a given enterprise.
In the
At least portions of the functionality of the deployment module 114, the template transfer module 116 and/or the virtualization platform integration module 118 may be implemented at least in part in the form of software that is stored in memory and executed by a processor.
The virtualization platform 122, as shown in
Additionally, the host devices 102, the orchestration engine 112 and/or the virtualization platform 122 can have an associated template datastore 106 configured to store virtual machine templates, as discussed further below in conjunction with
The host devices 102, the orchestration engine 112 and/or the virtualization platform 122 in the
The host devices 102, the orchestration engine 112 (or one or more components thereof such as the deployment module 114, template transfer module 116 and/or virtualization platform integration module 118) and the virtualization platform 122 may be implemented on respective distinct processing platforms, although numerous other arrangements are possible. For example, in some embodiments at least portions of one or more of the host devices 102, the orchestration engine 112 and the virtualization platform 122 are implemented on the same processing platform. The orchestration engine 112 and/or the virtualization platform 122 can therefore be implemented at least in part within at least one processing platform that implements at least a subset of the host devices 102.
The network 108 may be implemented using multiple networks of different types to interconnect storage system components. For example, the network 108 may comprise a portion of a global computer network such as the Internet, although other types of networks can be employed, including a wide area network (WAN), a local area network (LAN), a satellite network, a telephone or cable network, a cellular network, a wireless network such as a WiFi or WiMAX network, or various portions or combinations of these and other types of networks. The network 108 in some embodiments therefore comprises combinations of multiple different types of networks each comprising processing devices configured to communicate using Internet Protocol (IP) or other related communication protocols.
As a more particular example, some embodiments may utilize one or more high-speed local networks in which associated processing devices communicate with one another utilizing Peripheral Component Interconnect express (PCIe) cards of those devices, and networking protocols such as InfiniBand, Gigabit Ethernet or Fibre Channel. Numerous alternative networking arrangements are possible in a given embodiment, as will be appreciated by those skilled in the art.
The virtualization platform 122 in some embodiments may be implemented as part of a cloud-based system.
The host devices 102, the orchestration engine 112 and/or the virtualization platform 122 can be part of what is more generally referred to herein as a processing platform comprising one or more processing devices each comprising a processor coupled to a memory. A given such processing device may correspond to one or more virtual machines or other types of virtualization infrastructure such as Docker containers or other types of LXCs. As indicated above, communications between such elements of system 100 may take place over one or more networks.
The term “processing platform” as used herein is intended to be broadly construed so as to encompass, by way of illustration and without limitation, multiple sets of processing devices and one or more associated storage systems that are configured to communicate over one or more networks. For example, distributed implementations of the host devices 102 are possible, in which certain ones of the host devices 102 reside in one data center in a first geographic location while other ones of the host devices 102 reside in one or more other data centers in one or more other geographic locations that are potentially remote from the first geographic location. The virtualization platform 122 and the orchestration engine 112 may be implemented at least in part in the first geographic location, the second geographic location, and one or more other geographic locations. Thus, it is possible in some implementations of the system 100 for different ones of the host devices 102, the orchestration engine 112, and the virtualization platform 122 to reside in different data centers.
Numerous other distributed implementations of the host devices 102, the orchestration engine 112, and/or the virtualization platform 122 are possible. Accordingly, the host devices 102, the orchestration engine 112, and/or the virtualization platform 122 can also be implemented in a distributed manner across multiple data centers.
Additional examples of processing platforms utilized to implement portions of the system 100 in illustrative embodiments will be described in more detail below in conjunction with
It is to be understood that the particular set of elements shown in
It is to be appreciated that these and other features of illustrative embodiments are presented by way of example only, and should not be construed as limiting in any way.
For example, the particular sets of modules and other components implemented in the system 100 as illustrated in
The virtualization management server integration service 230 may be implemented, for example, at least in part as a vSphere™ integration service. The virtualization management server integration service 230 makes a secure connection 235 to a template and policy processing agent 260 of a virtualization platform 250, for example, using mTLS (Mutual Transport Layer Security) and certificates and a software development kit embedded in the virtualization management server integration service 230 to perform the necessary API calls to the template and policy processing agent 260 with the appropriate payloads and parameters.
In some embodiments, the template and policy processing agent 260 can be implemented, for example, using a container and/or a virtual machine and acts as an integration agent for orchestration engine 220.
If the template and policy processing agent 260 determines that the indicated template is not available in the inventory of the virtualization platform 250, the template and policy processing agent 260 will request the template from the orchestration engine 220, using a connection 240-1, or from a remote storage 290 identified by the provided storage location of the template, using a connection 240-2. The orchestration engine 220 and/or the remote storage 290 provide the requested template, using a connection 245-1 or 245-2, respectively. In some embodiments, the contents of the requested template may be signed and verified.
Once the template and policy processing agent 260 obtains the requested template, the template and policy processing agent 260 may cache the requested template and/or upload the requested template into the inventory of the virtualization platform 250, for example, using an application programming interface 255 of the virtualization platform 250 by means of a connection 258.
In addition, the template and policy processing agent 260 replicates (e.g., clones) the obtained template to create a virtual machine 270 to be generated using the deployment information. The created virtual machine 270 executes on one or more of a plurality of hypervisors 265-1 through 265-N (such as VMware™ ESXi™ hypervisors). The hypervisors 265 share a shared datastore 280, for example, to store application information associated with the virtual machine 270 and other applications.
In some embodiments, the template and policy processing agent 260 monitors the deployed virtual machine to enforce one or more policies.
In step 3, the virtualization management server integration service 230 makes a secure connection to the template and policy processing agent 260, for example, using a software development kit for the template and policy processing agent 260, and performs the necessary API calls with the received deployment information. The template and policy processing agent 260 then requests the template of the virtual machine to be created in step 4 from the virtualization management server integration service 230 or from the remote storage 290, using the storage location.
In step 5, the virtualization management server integration service 230 or the remote storage 290 securely provides the requested template to the template and policy processing agent 260. The template and policy processing agent 260 uploads the received template into the inventory of the virtualization platform 250 in step 6, for example, using a connection to the application programming interface 255.
The template and policy processing agent 260 replicates the replicates (e.g., clones) the received template in step 7 to create the virtual machine to be generated based on the deployment information. In step 8, the template and policy processing agent 260 monitors the deployed virtual machine to enforce one or more policies, as described herein.
The agent component then obtains the template for the virtual machine in step 408 from an orchestration engine and/or a remote data source identified by the storage location. In step 412, the agent component replicates the obtained template for the virtual machine to create the virtual machine.
In some embodiments, the request to deploy the virtual machine further comprises deployment information used to configure the virtual machine. The deployment information may comprise an identifier of the template for the virtual machine and/or a name of the virtual machine. The replicating of the obtained template for the virtual machine to create the virtual machine may process at least some of the deployment information to configure the virtual machine.
The agent may monitor an execution of the created virtual machine in some embodiments and evaluate one or more policies provided by the orchestration engine with respect to (i) security controls (e.g., to prevent an unauthorized intrusion or access of the virtual machine or other anomalous behavior) and/or (ii) network requirements associated with the created virtual machine. In addition, the agent may initiate one or more automated remedial actions in response to a detection of a violation of one or more of the policies.
The particular processing operations and other system functionality described in conjunction with the pseudo code and flow diagrams of
Advantageously, the virtual machine deployment techniques described herein allow a virtual machine to be deployed to a virtualization platform even when a template for the deployed virtual machine is not available in an inventory of the virtualization platform. In addition, the agent-based virtual machine deployment techniques provide a mechanism for the agent to monitor an execution of a deployed virtual machine and to detect and mitigate any violations of one or more applicable policies.
It is to be appreciated that the particular advantages described above and elsewhere herein are associated with particular illustrative embodiments and need not be present in other embodiments. Also, the particular types of information processing system features and functionality as illustrated in the drawings and described above are exemplary only, and numerous other arrangements may be used in other embodiments.

Numerous other types of computer program products comprising processor-readable storage media can be used.
Also included in the processing device 602-1 is network interface circuitry 614, which is used to interface the processing device with the network 604 and other system components, and may comprise conventional transceivers.
The other processing devices 602 of the processing platform 600 are assumed to be configured in a manner similar to that shown for processing device 602-1 in the figure.

For example, other processing platforms used to implement illustrative embodiments can comprise converged infrastructure.
It should therefore be understood that in other embodiments different arrangements of additional or alternative elements may be used. At least a subset of these elements may be collectively implemented on a common processing platform, or each such element may be implemented on a separate processing platform.
As indicated previously, components of an information processing system as disclosed herein can be implemented at least in part in the form of one or more software programs stored in memory and executed by a processor of a processing device. For example, at least portions of the functionality for deploying virtual machines to a virtualization management environment using an agent to obtain remote virtual machine templates as disclosed herein are illustratively implemented in the form of software running on one or more processing devices.
It should again be emphasized that the above-described embodiments are presented for purposes of illustration only. Many variations and other alternative embodiments may be used. For example, the disclosed techniques are applicable to a wide variety of other types of information processing systems, container orchestrators, etc. Also, the particular configurations of system and device elements and associated processing operations illustratively shown in the drawings can be varied in other embodiments. Moreover, the various assumptions made above in the course of describing the illustrative embodiments should also be viewed as exemplary rather than as requirements or limitations of the disclosure. Numerous other alternative embodiments within the scope of the appended claims will be readily apparent to those skilled in the art.
