gRPC on Ruby on Rails – a perfect match!
summary
Rails app adds gRPC by compiling .proto files with grpc-tools + grpc gem, generating people_pb.rb and service stubs and mounting an e‑commerce create_order RPC that returns create_order_response objects. A fleet tracking case runs ~10,000 devices, peaking at 56,000 invocations/hour, with gRPC containers CPU rising to ~12% and average response time 7–15 ms. Server runs on 0.0.0.0:5051 and keeps short open connections so Rails retains business logic without duplicating Node backends.
