Azure Service Fabric Endpoint vs Port

Question

This screenshot was taken while creating a Service Fabric Cluster. Apparently, all these marked fields are for adding ports. But some are called endpoints and some port. What's the difference?

Answer 1

You can understand in this context as:

endpoint a port that is available from outside your cluster.

Port just a port open in the node without actually being exposed externally.

Reverse Proxy is considered a port because it is not public available by default, you have to open it, becoming an endpoint.
