When scaling backend architecture, the communication layer between services eventually becomes a bottleneck. While REST over HTTP/1.1 with JSON payloads is the undisputed standard for public-facing web APIs, it introduces significant serialization overhead and lacks strict, enforceable contracts for internal, service-to-service communication. This is where gRPC shines. By leveraging HTTP/2 for multiplexed transport and Protocol Buffers (Protobuf) for efficient binary serialization, gRPC provide
