Abstract

A cloud based network includes a plurality of nodes, each of which include at least one containerized microservice that enables intent-driven operation of the cloud based network. One or more resource controllers, each designated to manage a custom resource, communicate with a master controller of the node to manage operational and configuration states of the node and any microservices containerized within the node. The master enables a user to monitor and automate the management of microservices and the cloud based network as a whole. The containerized microservice architecture allows user customizable rendering of microservices, reconciliation of old and new versions of microservices, and facilitated management of a plurality of nodes.

Claims

1. A cloud based network including a plurality of nodes, each node comprising:

a master controller;

one or more custom controllers managed by the master controller, the one or more custom controllers configured to access and store custom resources, each custom resource including;

an operational state of the node,

a configuration state of the node, and

a set of telemetry data representative of the node; and

one or more containerized microservices managed by at least one of the custom controllers.

2. The cloud based network of claim 1, wherein at least one containerized microservice enables a performance of one or more intent-driven operations within the cloud based network.

3. The cloud based network of claim 1, wherein the plurality of nodes is managed by an external system.

4. The cloud based network of claim 1, the node further comprising:

a host controller configured to instantiate the master controller and the custom controllers.

5. The cloud based network of claim 1, wherein data is stored external to the node and can be accessed on-demand.

6. The cloud based network of claim 5, wherein the master controller comprises an application programming interface (API) server, the master controller configured to establish a standard storage interface via the API server.

7. The cloud based network of claim 6, wherein the data stored external to the node is accessed by a custom controller via the standard storage interface.

8. The cloud based network of claim 1, wherein at least one custom controller is further configured to:

receive, from the master controller;

a desired operational state of the node, and

a desired configuration state of the node;

reconcile the operational state and the desired operational state of the node; and

reconcile the configuration and the desired configuration of the node.

9. The cloud based network of claim 1, the master controller is further configured to:

receive, from a microservice;

an operational state of the microservice, and

a configuration state of the microservice, the operational state and the configuration state associated with a current version of the microservice;

provide, to the microservice;

a second operational state of the microservice, and

a second configuration state of the microservice, the second operational state and the second configuration state associated with a second version of the microservice;

reconcile the current version and the second version of the microservice with one or more other microservices.

10. The cloud based network of claim 1, wherein at least one containerized microservice is a command line interface (CLI) microservice configured to render the custom resources stored by the custom controllers for display to a node operator.

11. The cloud based network of claim 1, wherein the plurality of nodes comprises a cluster, and wherein the cluster comprises one of a plurality of clusters each comprising a corresponding set of nodes within the cloud based network.

12. The cloud based network of claim 11, wherein at least one cluster is an external cluster, the external cluster comprising:

a plurality of master controllers, each master controller configured to manage a cluster of the plurality of clusters; and

a fabric controller.

13. The cloud based network of claim 12, wherein the fabric controller is configured to:

monitor each of the plurality of master controllers;

manage each of the plurality of master controllers;

access each of the plurality of nodes within each cluster; and

manage each of the plurality of nodes within each cluster.

14. A method for managing a cloud based network comprising:

generating and managing a plurality of nodes, each node comprising;

a master controller;

one or more custom controllers; and

one or more containerized microservices; and

wherein managing each of the nodes comprises;

managing, by the master controller, the one or more custom controllers;

managing, by at least one custom controller, the one or more containerized microservices; and

accessing and storing custom resources, each custom resource comprising;

an operational state of the node;

a configuration state of the node; and

a set of telemetry data representative of the node.

15. The method of claim 14, wherein at least one containerized microservice enables a performance of one or more intent-driven operations within the cloud based network.

16. The method of claim 14, wherein the plurality of nodes is managed by an external system.

17. The method of claim 14, wherein each node further comprises:

a host controller configured to instantiate the master controller and the custom controllers.

18. The method of claim 14, wherein at least one custom controller is configured to:

receive, from the master controller;

a desired operational state of the node, and

a desired configuration state of the node;

reconcile the operational state and the desired operational state of the node; and

reconcile the configuration and the desired configuration of the node.

19. The method of claim 14, wherein the master controller is further configured to:

receive, from a microservice;

an operational state of the microservice, and

a configuration state of the microservice, the operational state and the configuration state associated with a current version of the microservice;

provide, to the microservice;

a second operational state of the microservice, and

a second configuration state of the microservice, the second operational state and the second configuration state associated with a second version of the microservice; and

reconcile the current version and the second version of the microservice with one or more other microservices.

20. The method of claim 19, wherein at least one containerized microservice is a command line interface (CLI) microservice configured to render the custom resources stored by the custom controllers for display to a node operator.
