Beyond REST: Architecting High-Performance Microservices with gRPC in Go
The article explores using gRPC in Go to build high-performance microservices, highlighting its advantages over REST for internal service-to-service communication. It demonstrates a practical three-tier architecture with a gRPC frontend and a REST backend for a pharmacy inventory system. The guide covers contract definition with Protocol Buffers, code generation, and implementation of unary and streaming RPCs.
- ▪gRPC uses HTTP/2 and Protocol Buffers to enable low-latency, typed communication between microservices.
- ▪The example architecture includes a gRPC server on port 50051 that communicates with a REST API on port 8080.
- ▪Protobuf serves as a strict contract, ensuring compatibility between client and server through generated Go code.
- ▪The service supports both unary RPC for single requests and server-side streaming for continuous data push.
- ▪Prerequisites include Go 1.22+, the protoc compiler, and Go plugins for Protobuf and gRPC code generation.
