Generating XML configuration sub-streams based on an XML configuration stream and a metadata tree associated with the XML configuration stream

Abstract

In some implementations, a system may receive an extensible markup language (XML) configuration stream that indicates one or more resource configurations. The system may maintain a data model that includes metadata that describes the XML configuration stream. The system may process the data model to generate a metadata tree. The system may generate, based on the XML configuration stream and the metadata tree, one or more XML configuration sub-streams that are respectively associated with a subset of the one or more resource configurations. The system may process, using respective resource processing modules of the system, the one or more XML configuration sub-streams to generate respective information associated with the subset of the one or more resource configurations.

Description

BACKGROUND

A network device (e.g., a router, a switch, or another network device) can support one or more resources (also referred to as services), such as a security resource, an interface resource, and/or a routing-policy resource. The one or more resources may be configured according to a configuration file (e.g., that indicates one or more resource configurations) included in the network device, which may be formatted according to an extensible markup language (XML).

SUMMARY

In some implementations, a method includes receiving, by a system, an XML configuration stream that indicates one or more resource configurations; maintaining, by the system, in the form of a data model, metadata that describes the XML configuration stream; processing, by the system, the data model to generate a metadata tree; generating, by the system and based on the XML configuration stream and the metadata tree, one or more XML configuration sub-streams that are respectively associated with a subset of the one or more resource configurations; and processing, by the system and using respective resource processing modules of the system, the one or more XML configuration sub-streams to generate respective information associated with the subset of the one or more resource configurations.

In some implementations, a non-transitory computer-readable medium storing a set of instructions includes one or more instructions that, when executed by one or more processors of a system, cause the system to: receive an XML configuration stream; maintain a data model associated with the XML configuration stream; process the data model to generate a metadata tree; and generate, based on the XML configuration stream and the metadata tree, one or more XML configuration sub-streams.

In some implementations, a system includes one or more memories; and one or more processors to: process an XML configuration stream that indicates one or more resource configurations to generate a metadata tree; generate, based on the XML configuration stream and the metadata tree, one or more XML configuration sub-streams that are respectively associated with a subset of the one or more resource configurations; and process, using respective resource processing modules of the system, the one or more XML configuration sub-streams to generate respective information associated with the subset of the one or more resource configurations.

DETAILED DESCRIPTION

The following detailed description of example implementations refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.

A network management system can manage multiple, different network devices in a network. In some cases, a configuration of a network device may be updated (e.g., by the network management system, or by another device, such as a client device of a network administrator). Accordingly, the network device (or another device, such as the client device) may provide an XML configuration stream to the network management system. The XML configuration stream may be a stream of the configuration file that has been updated to cause the network device to be updated. The network management system may analyze the XML configuration stream to determine how the configuration of the network device has been updated and/or what updates should be made to other network devices in the network (e.g., to ensure consistency and/or compatibility among the network devices), among other examples.

Typically, to analyze the XML configuration stream, the network management system waits until the entire XML configuration stream is received and then analyzes the XML configuration stream. The network management system then uses different filters to identify sections of the XML configuration streams that are associated with particular resource configurations, which is a serial process. Further, when the network management system needs to translate some or all of the XML configuration stream into another version (e.g., a vendor neutral representation, such as an OpenConfig representation) to enable updating of other, different network devices, the network management system can use a transformation technique (e.g., an extensible stylesheet language transformation (XSLT) technique) that requires generation of a document object model (DOM) of the XML configuration stream. XSLT 3.0 tries to improve over XSLT 2.0 with respect to reducing the size of source document and result document maintained in memory, but still while evaluating the XPATH expressions the intermediate results are stored in variables in evaluation-context. Moreover, these transformations cannot be distributed across multiple machines to reduce the memory and compute resources used from one single machine. These approaches are computing intensive (e.g., consume large amounts of computing resources, such as processing resources, memory resources, communication resources, and/or power resources, among other examples) and/or time intensive (e.g., require idle time and/or require lengthy calculations to be performed that consume multiple computing cycles). If such transformations are carried out on the Kubernetes based deployments, then there is always a possibility of single POD executing these transformations exceeding its allocated CPU and memory resources, causing Kubernetes orchestrator to restart the POD.

Some implementations described herein provide a network management system (NMS). The NMS receives an XML configuration stream that indicates one or more resource configurations. The NMS maintains a data model (e.g., a “minimal” data model) describing the XML configuration stream, and then processes the data model to generate a metadata tree. The NMS may include in the data model one or more data elements that correspond to the one or more resource configurations, and may cause particular data elements to include additional parameters to identify the particular data elements and/or to indicate that the particular data elements are of interest (e.g., that the particular data elements correspond to resource configurations that are relevant to configuring other network devices). The metadata tree may therefore include only nodes that are associated with resource configurations of interest (e.g., based on the parameters of the particular data elements). The NMS (e.g., using a general processing module) then processes the XML configuration stream and the metadata tree (e.g., simultaneously, in a combined process) to generate one or more XML configuration sub-streams. For example, the NMS may identify subtrees of the metadata tree that are associated with a particular resource configuration and may thereby cause elements (and attributes) of the XML configuration stream to be included in an XML configuration sub-stream associated with the particular resource configuration.

In this way, the NMS is able to process the XML configuration stream and dynamically generate the one or more XML configuration sub-streams (e.g., without waiting for the XML configuration stream to be fully received and stored in transient or intermediary storage). Further, by using a metadata tree (e.g., that is generated based on a minimal data model), the NMS is able to “filter” the XML configuration stream without modifying the XML configuration stream or needing to maintain a separate copy of the XML configuration stream. The NMS, therefore, to generate the one or more XML configuration sub-streams, uses fewer computing resources (e.g., processing resources, memory resources, communication resources, and/or power resources, among other examples) and can do so in less time than a network management system that uses a typical approach. Additionally, because a minimal data model is maintained, the NMS does not need to account for specific or unique attributes of the XML configuration stream (including all the attributes that can cause the data model to exponentially grow in size), which further conserves resources. Further, because the minimal data model is associated with high-level features of the XML configuration stream, the minimal data model may be provided to the NMS (e.g., by another device, such as via a Kubernetes custom resource definition (CRD) functionality) rather than maintained by the NMS, which improves the operational efficiency of the system where the CRD can be updated to include the new resources to generate additional sub-streams without requiring redeployment or restart of NMS.

Moreover, the NMS may include one or more resource processing modules that are configured to process the one or more XML configuration sub-streams. Each resource processing module may be associated with a resource and may be configured to process an XML configuration sub-stream that is associated with the resource. Accordingly, the resource processing module may be optimized to process the XML configuration sub-stream, and may use computing resources that are allocated to the resource processing module (rather than computing resources allocated to the general/main processing module of the NMS). This conserves computing resources allocated to the general/main processing module. Further, the one or more resource processing modules may operate in parallel, which allows for a more efficient use of computing resources allocated to processing modules of the NMS, and also improves a computing time performance of the NMS (e.g., to generate information associated with the one or more XML configuration sub-streams). Once the sub-stream is read by a resource processing module it may proceed independent of the other resource processing modules to operate on that sub-stream.

FIGS. 1A-1D are diagrams of one or more example implementations 100 described herein. As shown in FIGS. 1A-1D, example implementation(s) 100 may include an NMS and a network device. The NMS and the network device are described in more detail below in connection with FIGS. 2-4. As shown in FIGS. 1A-1D, the NMS may include a general processing module, and one or more resource processing modules (shown as resource processing modules 1 through N, where N>1). The general processing module may be configured to perform general processing tasks of the NMS, and each resource processing module may be configured to perform processing tasks for an associated resource. For example, a resource 1 processing module may be configured to perform processing tasks associated with a resource 1, a resource 2 processing module may be configured to perform processing tasks associated with a resource 2, and so on.

As shown in FIG. 1A, and by reference number 102, the NMS may receive an XML configuration stream. For example, a network device may provide the XML configuration stream to the NMS, and the NMS may thereby receive the XML configuration stream from the network device. In some implementations, the NMS may receive the XML configuration stream from another device (e.g., another network device, a client device, a server device, or another type of device) or a data structure (e.g., a database, a table, a file, or another type of data structure). The XML configuration stream may include a plurality of elements, such as sets of elements that each include a start element and corresponding end element (e.g., as shown in FIGS. 2A-2D), wherein a set of elements may be associated with one or more attributes. That is, the XML configuration stream may be structured in an XML format. Accordingly, the XML configuration stream may indicate one or more resource configurations, such as for the network device (e.g., that provided the XML configuration stream to the NMS). For example, the XML configuration may indicate (e.g., by a first set of elements and one or more attributes of the first set of elements) one or more configurations for a first resource, may indicate (e.g., by a second set of elements and one or more attributes of the second set of elements) one or more configurations for a second resource, and so on.

As shown by reference number 104, the NMS may maintain a data model. The data model may include metadata that describes the XML configuration stream (e.g., the data model may include metadata that provides information about a structure of the XML configuration stream). For example, for each resource configuration indicated by the XML configuration, the data model may include a data element that corresponds to the resource configuration. The data model may be, for example, a “yet another next generation” (YANG) data model. In some implementations, the data model may represent at least some information associated with the one or more resource configurations indicated by the XML configuration stream. For example, the data model may include one or more data elements that identify the one or more resource configurations. In some implementations, the one or more data elements may not represent specific configuration details associated with the one or more resource configurations. Accordingly, the data model may be considered to be a “minimal” data model (e.g., a minimal YANG data model).

In some implementations, the NMS (e.g., using the general processing module) may maintain the data model such that the data model includes additional information (e.g., that is not included in the XML configuration stream). For example, the data model may include a data element that corresponds to a resource configuration (e.g., that is indicated by the XML configuration stream), wherein the data element includes one or more parameters. For example, a first parameter may indicate that the data element (for example, and/or the corresponding resource configuration) is of interest, such as for further processing by the NMS; and/or a second parameter may indicate an identifier (e.g., an alphanumeric string, or other identifier) that is associated with the data element (and/or the corresponding resource configuration). As a specific example, as further shown in FIG. 1A, the data model may include a “system” data element associated with a “system” resource configuration (shown as “container system”) that includes a first parameter (shown as “jcr:config-filter”) that indicates that the system data element (and/or the system resource configuration) is of interest, and a second parameter (shown as “jcr:config-resource ‘System’”) that is an identifier that is associated with the system data element (and/or the system resource configuration).

In some implementations, the data model may be represented as a Kubernetes CRD. With this approach, it is possible to generate new sub-streams (as described herein) by updating the CRD to include a data element that includes one or more parameters. Accordingly, the system may include other processing modules to process the new sub-streams. Further, the system may maintain a mapping between sub-streams and corresponding processing modules. This approach is extensible and new sub-streams can be included without requiring restart of any of the existing processing modules.

As shown in FIG. 1B, and by reference number 106, the NMS may process the data model to generate a metadata tree. The metadata tree may include, for example, one or more nodes that correspond to one or more data elements of the data model. Accordingly, a node of the metadata tree may correspond to a data element of the data model, and therefore may correspond to a resource configuration of the XML configuration stream (e.g., because the data element corresponds to the resource configuration). Each node may identify the data element that the node corresponds to, and may include, for example, one or more parameters of the data element (e.g., a first parameter and/or a second parameter included in the data element, as described above). As a specific example, as further shown in FIG. 1B, the metadata may include a “system” node (e.g., that corresponds to the system data element of the data model, and therefore corresponds with the system resource configuration) that includes a second parameter (shown as “config-resource ‘System’”) that is an identifier that is associated with the system data element (and/or the system resource configuration).

In some implementations, the metadata tree may include only nodes that correspond to data elements of the data model that each include a first parameter (e.g., that indicates that the data element, and/or the corresponding resource configuration, is of interest, such as for further processing by the NMS). For example, the metadata tree may include only nodes that correspond to data elements with a “jcr: config-filter” parameter. In some implementations, the metadata tree may include nodes that correspond to data elements that have a first parameter, and that descend from (e.g., are children of) data elements that have the first parameter. In this way, the metadata tree may be considered to be “filtered” to include nodes that are associated with resource configurations that are of interest, and, optionally, resource configurations associated with the resource configurations that are of interest.

As shown in FIG. 1C, and by reference number 108, the NMS may generate one or more XML configuration sub-streams (e.g., based on the XML configuration stream and the metadata tree). For example, the NMS may process (e.g., parse, decode, and/or perform one or more other processing techniques) the XML configuration stream and may process (e.g., traverse and/or perform one or more other processing techniques) the metadata tree (e.g., simultaneously, as part of a combined process) to generate the one or more XML configuration sub-streams. The one or more XML configuration sub-streams may be respectively associated with a subset (e.g., that includes at least one resource configuration) of the one or more resource configurations (e.g., that are indicated by the XML configuration stream). For example, the NMS may generate an XML configuration sub-stream for the resource 1 and the resource N (but not for the resource 2).

In some implementations, when the NMS is processing the XML configuration stream and the metadata tree, the NMS may identify a start element (e.g., that is associated with a resource configuration) of the XML configuration stream. The NMS then may determine whether a node of the metadata tree is associated with the start element (e.g., whether the node corresponds to the resource configuration). When the NMS does not identify a node that is associated with the start element, the NMS may ignore the start element, and one or more other elements that are associated with the start element (e.g., an end element that corresponds to the start element, and/or one or more other elements that are child elements of the start element). Alternatively, when the NMS identifies a node that is associated with the start element, the NMS may cause a stream writer to be created (e.g., as a processing instance within the general processing module of the NMS). The stream writer may be configured to generate an XML configuration sub-stream (e.g., based on information provided to the stream writer by the NMS, as described herein).

In some implementations, the NMS (e.g., after causing the stream writer to be created) may generate an XML snippet (e.g., based on processing the XML configuration stream and the metadata tree). The NMS may provide the XML snippet to the stream writer, which may allow the stream writer to generate a particular XML configuration sub-stream. The particular XML configuration sub-stream may include a portion of the XML configuration stream, such that the particular XML configuration sub-stream indicates one or more configuration settings of the resource configuration (e.g., that is associated with the start element).

In some implementations, to generate the XML snippet, the NMS may identify another start element of the XML configuration stream (e.g., that is a child element of the start element described above). The NMS then may identify another node of the metadata tree that is associated with the other start element. Accordingly, the NMS may determine (e.g., based on the other node) whether the other start element is to be included in the XML snippet.

For example, the NMS may determine that the other node is associated with a data element of the data model, and that the other node includes a second parameter (e.g., that indicates an identifier that is associated with the data element). The other start element may be a parent element in a set of elements (e.g., that includes the other start element and a corresponding end element, and one or more child elements of the other start element) of the XML configuration stream. The NMS may therefore determine (e.g., based on determining that the other node includes a second parameter) that the set of elements are to be included in the XML snippet, and may thereby generate the XML snippet to include the set of elements (and, optionally, respective attributes of the set of elements). In this way, the XML snippet may be generated to include elements (and attributes) that are associated with the resource configuration.

As another example, the NMS may determine that the other node is associated with a data element of the data model, and that the other node does not include a second parameter. The NMS may therefore determine that the other start element is to not be included in the XML snippet, and may thereby generate the XML snippet to not include the other start element. Alternatively, the NMS may determine that the other start element is a child element of another element of the XML configuration stream (e.g., that is a child element of the start element) that is associated with a node that includes a second parameter. Accordingly, because the other element is to be included in the XML snippet (e.g., for one or more reasons described elsewhere herein), the NMS may determine that the other start element is to be included in the XML snippet, and may thereby generate the XML snippet to include the other start element (and, optionally, one or more attributes of the other start element). In this way, the XML snippet may be generated to include elements (and attributes) that are associated with other elements that are associated with the resource configuration.

In an additional example, the NMS may determine that the other node is associated with a data element of the data model, and that the other node is a leaf node of the metadata tree. The other start element may be a parent element of a set of elements (e.g., that includes child elements of the other start element) of the XML configuration stream. The NMS may therefore determine (e.g., based on determining that the other node is a leaf node of the metadata tree) that the set of elements are to be included in the XML snippet, and may thereby generate the XML snippet to include the set of elements. In this way, the XML snippet may be generated to include elements that are associated with the resource configuration, but that are not represented in the metadata tree, to maintain a hierarchical structure of start elements of the XML configuration stream in the XML snippet.

In some implementations, the NMS may determine that the other node of the metadata tree does not include a second parameter and that the other start element is not a child element of another element of the XML configuration stream that is to be included in the XML snippet. The NMS may therefore cause the other start element to be stored in a data structure (e.g., a stack, a queue, or another type of data structure) that stores start elements. In some implementations, the NMS may generate the XML snippet to include one or more elements (and, optionally, respective attributes of the one or more elements), such as for one or more reasons described elsewhere herein, and the NMS may therefore determine that one or more start elements of the data structure are to be included in the XML snippet. The NMS may generate the XML snippet to include (or to further include) the one or more start elements. In this way, a hierarchical structure of start elements of the XML configuration stream may be maintained in the XML snippet.

In some implementations, the NMS may identify an end element of the configuration stream that is associated with the start element (e.g., the end element corresponds to the start element). The NMS may therefore determine whether the data structure includes any start element (e.g., whether the data structure is full, or empty). For example, the NMS may identify that the data structure is storing one or more start elements (e.g., that are child elements of the start element), and may therefore generate one or more end elements that are respectively associated with the one or more start elements. The NMS then may generate the XML snippet to include the one or more end elements. In this way, the NMS facilitates a proper formatting (e.g., XML formatting) of the XML snippet.

After the NMS has generated the one or more XML configuration sub-streams, the NMS may flush (e.g., drop or remove) the XML configuration stream from the NMS. The NMS may also flush the data structure described herein (e.g., remove any start elements stored in the data structure). This frees up computing resources (e.g., processing resources, memory resources, communication resources, and/or power resources, among other examples) that would otherwise be used to maintain the XML configuration stream and/or the contents of the data structure in the NMS.

As shown in FIG. 1D, and by reference number 110, the NMS (e.g., using the one or more resource processing modules) may process the one or more XML configuration sub-streams to generate respective information associated with the subset of the one or more resource configurations. For example, the NMS may process, using the resource 1 processing module, an XML configuration sub-stream that is associated with a resource configuration for the resource 1 to generate information associated with the resource configuration for the resource 1; the NMS may process, using the resource 2 processing module, an XML configuration sub-stream that is associated with a resource configuration for the resource 2 to generate information associated with the resource configuration for the resource 2; and so on. In some implementations, the one or more resource processing modules may respectively process the one or more XML configuration sub-streams in parallel (e.g., at one or more overlapping times). Accordingly, by processing the one or more resource processing modules in this way, computing resources (e.g., processing resources, memory resources, communication resources, and/or power resources, among other examples) of the general processing module may be conserved, and the respective information associated with the one or more resource configurations may be generated more quickly than if the one or more XML configuration sub-streams were to be serially processed.

In some implementations, information associated with a resource configuration may include a translated version of an XML configuration sub-stream that is associated with the resource configuration. For example, the NMS may process (e.g., using the resource processing module associated with the resource configuration, and using a translation technique) the XML configuration sub-stream to generate the translated version of the XML configuration sub-stream. The translated version of the XML configuration sub-stream may be in a format (e.g., a vendor neutral format), such that the XML configuration sub-stream may be processed by a device (e.g., another network device) to allow the resource configuration for the device to be updated (e.g., according to the XML configuration sub-stream). Accordingly, the NMS may provide the translated version of the XML configuration sub-stream to the device, which may allow the device to update the resource configuration for the device.

In some implementations, information associated with a resource configuration may include update information associated with the resource configuration. The update information may indicate, for example, one or more out-of-band changes to the resource configuration, and/or one or more other modifications (e.g., one or more modified Xpaths) to the resource configuration. The NMS may process (e.g., using the resource processing module associated with the resource configuration, and using a comparison technique) the XML configuration sub-stream and another XML configuration sub-stream (e.g., a prior version of the XML configuration sub-stream) to determine the update information. The NMS may provide the update information to another device (e.g., another network device) to allow the resource configuration for the device to be updated (e.g., according to the update information).

In some implementations, using respective resource processing modules of the NMS to process the one or more XML configuration sub-streams allows for at least one of: the processing of the XML configuration across multiple processing modules, or the resource processing modules of the system and the general processing module of the system to not exceed respective resource allocations (e.g., compute and/or memory resource allocations).

As indicated above, FIGS. 1A-1D are provided as an example. Other examples may differ from what is described with regard to FIGS. 1A-1D.

FIGS. 2A-2G are diagrams of an example 200 related to an XML configuration stream, a data model that describes the XML configuration stream, and XML configuration sub-streams that are associated with the XML configuration stream. The NMS may process the XML configuration stream (e.g., based on the data model) to generate the XML configuration sub-streams, as described herein in relation to FIGS. 1A-1D.

As shown in FIG. 2A, the XML configuration stream may indicate configurations for a system resource (indicated by the start element <system> and the end element </system>), an interfaces resource (indicated by the start element <interfaces> and the end element </interfaces>), a protocol resource (indicated by the start element <protocol> and the end element </protocol>), a security resource (indicated by the start element <security> and the end element </security>), and a routing policy resource (indicated by the start element <routing-policy> and the end element </routing-policy>). As further shown in FIG. 2A, the XML configuration stream may indicate configurations for resources (e.g., sub-resources) that are associated with the security resource, such as configurations for a zones resource (indicated by the start element <security> and the end element </security>), and a security-zone resource (indicated by the start element <security-zone> and the end element </security-zone>), which is a sub-resource of the zones resource (and therefore a sub-sub-resource of the security resource).

As shown in FIGS. 2B-2D, the data model may include data elements that correspond to the resources indicated by the XML configuration stream (e.g., that are shown in FIG. 2A). For example, the data model may include a system data element (indicated by a system-group identifier, as shown in FIG. 2B) that corresponds to the system resource, an interfaces data element (e.g., indicated by a interfaces-group identifier, as shown in FIG. 2C) that corresponds to the interface resource, and a security data element (e.g., indicated by a security-group identifier, as shown in FIG. 2D) that corresponds to the security resource. As further shown in FIG. 2D, the data model may include data elements that correspond to sub-resources of the security resource, such as a zones data element (e.g., indicated by a zones identifier) and a security-zone data element (e.g., indicated by a security-zone identifier).

As shown in FIG. 2E, the NMS may process the XML configuration stream (e.g., using the data model) to generate a system resource XML configuration sub-stream (e.g., for processing by a system processing module of the NMS). As shown in FIG. 2F, the NMS may process the XML configuration stream (e.g., using the data model) to generate an interfaces resource XML configuration sub-stream (e.g., for processing by an interfaces processing module of the NMS). As shown in FIG. 2G, the NMS may process the XML configuration stream (e.g., using the data model) to generate a security-zone resource XML configuration sub-stream (e.g., for processing by a security-zone processing module of the NMS).

As indicated above, FIGS. 2A-2G are provided as an example. Other examples may differ from what is described with regard to FIGS. 2A-2G.

FIG. 3 is a diagram of an example environment 300 in which systems and/or methods described herein may be implemented. As shown in FIG. 3, environment 300 may include an NMS 301, which may include one or more elements of and/or may execute within a cloud computing system 302. The cloud computing system 302 may include one or more elements 303-312, as described in more detail below. As further shown in FIG. 3, environment 300 may include a network 320, and/or a network device 330. Devices and/or elements of environment 300 may interconnect via wired connections and/or wireless connections.

The cloud computing system 302 may include computing hardware 303, a resource management component 304, a host operating system (OS) 305, and/or one or more virtual computing systems 306. The cloud computing system 302 may execute on, for example, an Amazon Web Services platform, a Microsoft Azure platform, or a Snowflake platform. The resource management component 304 may perform virtualization (e.g., abstraction) of computing hardware 303 to create the one or more virtual computing systems 306. Using virtualization, the resource management component 304 enables a single computing device (e.g., a computer or a server) to operate like multiple computing devices, such as by creating multiple isolated virtual computing systems 306 from computing hardware 303 of the single computing device. In this way, computing hardware 303 can operate more efficiently, with lower power consumption, higher reliability, higher availability, higher utilization, greater flexibility, and lower cost than using separate computing devices.

The computing hardware 303 may include hardware and corresponding resources from one or more computing devices. For example, computing hardware 303 may include hardware from a single computing device (e.g., a single server) or from multiple computing devices (e.g., multiple servers), such as multiple computing devices in one or more data centers. As shown, computing hardware 303 may include one or more processors 307, one or more memories 308, and/or one or more networking components 309. Examples of a processor, a memory, and a networking component (e.g., a communication component) are described elsewhere herein.

The resource management component 304 may include a virtualization application (e.g., executing on hardware, such as computing hardware 303) capable of virtualizing computing hardware 303 to start, stop, and/or manage one or more virtual computing systems 306. For example, the resource management component 304 may include a hypervisor (e.g., a bare-metal or Type 1 hypervisor, a hosted or Type 2 hypervisor, or another type of hypervisor) or a virtual machine monitor, such as when the virtual computing systems 306 are virtual machines 310. Additionally, or alternatively, the resource management component 304 may include a container manager, such as when the virtual computing systems 306 are containers 311. In some implementations, the resource management component 304 executes within and/or in coordination with a host operating system 305.

A virtual computing system 306 may include a virtual environment that enables cloud-based execution of operations and/or processes described herein using computing hardware 303. As shown, a virtual computing system 306 may include a virtual machine 310, a container 311, or a hybrid environment 312 that includes a virtual machine and a container, among other examples.
