== Managing Resource Servers According to the OAuth2 specification, a Resource Server is the server hosting the protected resources and capable of accepting and responding to protected resource requests.

Any client application can be configured to support fine-grained permissions. When you do that, you are conceptually turning the client application into a resource server.
