Yeah we have a similar situation. Protobuf is fine but gRPC adds a ton of additional complexity and operational costs. If the main goal is to have a more formal api definition and you don’t need the streaming and multiplexing from gRPC then I would look at GitHub - twitchtv/twirp: A simple RPC framework with protobuf service definitions · GitHub. I’m exploring an elixir implementation for work because it allows an easy on road into our existing ecosystems and solves the main pain points we have.
