Remote Procedure Call (RPC)

In real-world systems, systems must often delegate tasks to other systems. This is RPC - a system calls another system over the network, and something gets executed in the process.


RPC is by design REQUEST-RESPONSE. A request comes in with an optional payload, a reply is given with an optional payload. It usually operates over TCP with a specific encoding schema, but that isn't necesarily the case.

Google's grpc package operates over HTTP/2 with binary encoding enabled. Since HTTP/2 is TLS enabled this means that inter-process communication is encrypted by default.

Status Codes

As HTTP is used, you can either use the HTTP status codes - or the grpc defined ones - The grpc codes have been optimized for rpc, though they're less well known. There's an implicit assumption that the grpc package will be used for that specific purpose.
