Abstract: Techniques are described by which a fabric designer system provides a user interface (UI) to enable a user to design a data center fabric. For example, a fabric designer system comprises processor(s) and a memory comprising instructions that when executed by the processor(s) cause the one or more processors to: generate data representative of a user interface (UI) for display on a display device, the data representative of the UI comprising UI elements representing one or more fabric design requirements receive, via the UI on the display device, an indication of a user input selecting one or more of the UI elements representing the one or more fabric design requirements; generate a model for a data center fabric based on the one or more fabric design requirements and a catalog of network devices; and generate UI elements representing fabric design specifications of the model for the data center fabric.

Abstract: In an example, a network controller for an SDN architecture system includes processing circuitry of a central cluster of first one or more compute nodes; a configuration node configured for execution by the processing circuitry; a control node configured for execution by the processing circuitry. The configuration node includes a custom API server to process requests for operations on custom resources for SDN architecture configuration. Each of the custom resources for SDN architecture configuration corresponds to a type of configuration object in the SDN architecture system. The control node, in response to detecting an event on an instance of a first custom resource of the custom resources, obtains configuration data for the instance of the first custom resource and configures a corresponding instance of a configuration object in a workload cluster of second one or more compute nodes. The first and second compute nodes may be distinct.
