NSX Manager deployment consideration
Due to the critical role NSX plays in a vSphere environment, it is extremely important to know and implement NSX management, control plane and data plane features. NSX management is NSX Manager, which provides a single point for configuring all NSX features and in addition we can leverage REST-API calls for deployment, configuration, and other tasks. So let's talk about communication channels from the management plane to other components.
