gRPC server for micro services how to?

[Greg Keys]

I'm brand new to gRPC coming from websockets using crossbar.io. 

The way we are used to working is basically services and clients all connect to a single router which facilitates communication between services and consumers/clients

Can someone tell me how gRPC web clients talk to multiple backend services via a single connection, is it more like REST where if a client wants to call the auth service is posts to /auth and to get a profile it does a get request to /profile

or do I need to create a single backend service to act as a server/router which other services register to?

Hi Greg,

gRPC micro services are not much different form REST micro services. Each micro service can exist independently inside your site. When a web client tries to access a particular service, what typically happens is traffic would go through a reverse proxy deployed at the edge of your site. The reverse proxy is where the web client has a single connection to, and it is responsible for routing requests to the correct micro service. Some examples of reverse proxies are envoy and nginx. Hope that helps!
