Development of a Language-Independent Microservice Architecture

The document explains how to build a multilingual microservice architecture using gRPC and Protocol Buffers instead of REST, highlighting benefits like performance (HTTP/2, bidirectional streaming), single source of truth for data structures, and cross-language compatibility. It outlines a four-step process—defining services in .proto files, selecting target languages, compiling with Docker-based tooling (namely/protoc-all) to generate boilerplate, and implementing gRPC servers and clients—with concrete examples in Go (server) and Node.js (client). The guide also covers optional REST proxy generation, CI/CD integration for automated code generation, and packaging proto outputs for language-specific ecosystems.
