SkyWalking has default activated gRPC/HTTP servers in the core module, which serve for both internal communication and external data report or query.
In some advanced scenarios, such as security requirements, specific gRPC/HTTP servers should be exposed for external requests.

Set restPort
(HTTP) and gRPCPort
(gRPC) to a legal port(greater than 0), would initialize new gRPC/HTTP servers for external requests with other relative settings. In this case, core/gRPC
and core/rest
could be served for cluster internal communication only.
