Cloud native software-defined network architecture for multiple clusters

A method comprising:

• processing, by a custom application programming interface (API) server implemented by a configuration node of a network controller for a software-defined networking (SDN) architecture system, requests for operations on custom resources for SDN architecture configuration, wherein each of the custom resources for SDN architecture configuration corresponds to a type of configuration object in the SDN architecture system, wherein the network controller operates on a central cluster of first one or more compute nodes, wherein the central cluster is separate from a workload cluster that executes on one or more virtual execution elements, and wherein the configuration node is executed by the central cluster;
• based on detection of a native resource operation comprising a create event on a native resource of the workload cluster, causing, by the configuration node of the network controller, an event on an instance of a first custom resource of the custom resources in the central cluster;
• detecting, by a control node of the network controller, the event on the instance of the first custom resource of the custom resources, wherein the control node is executed by the central cluster;
• and
• by the control node, based on detecting the event on the instance of the first custom resource, obtaining configuration data for the instance of the first custom resource and configuring a corresponding instance of a configuration object in the workload cluster of second one or more compute nodes, wherein the first one or more compute nodes of the central cluster and the second one or more compute nodes of the workload cluster are distinct.

A non-transitory computer-readable medium comprising instructions for causing processing circuitry to:

• process, by a custom application programming interface (API) server implemented by a configuration node of a network controller for a software-defined networking (SDN) architecture system, requests for operations on custom resources for SDN architecture configuration, wherein each of the custom resources for SDN architecture configuration corresponds to a type of configuration object in the SDN architecture system, wherein the network controller operate on a central cluster of first one or more compute nodes, and wherein the central cluster is separate from a workload cluster that executes one or more virtual execution elements, and wherein the configuration node is executed by the central cluster;
• based on detection of a native resource operation comprising a create event on a native resource of the workload cluster, cause, by the configuration node of the network controller, an event on an instance of a first custom resource of the custom resources in the central cluster;
• detect, by a control node of the network controller, the event on the instance of the first custom resource of the custom resources, wherein the control node is executed by the central cluster;
• and
• by the control node, based on detecting the event on the instance of the first custom resource, obtain configuration data for the instance of the first custom resource and configure a corresponding instance of a configuration object in the workload cluster of second one or more compute nodes, wherein the first one or more compute nodes of the central cluster and the second one or more compute nodes of the workload cluster are distinct.
