Service Communication

Services Communication Design

TL;DR The plan is to use protobuf for the format. Message calls should be made with gRPC when the client wants a response. High level messages should also be published to the bus. Message calls (events) that don't require a response can just be published to the bus.

There are 3 parts to consider:
  • Messaging format
  • Client calls that require a response - RPC
  • Publishing events - BUS

Messaging Format

The message format must be statically typed, binary, good adoption and have RPC integration.
