Go API Gateway + gRPC
Go is the language of the cloud. This stack utilizes its concurrency primitives to handle massive throughput at the gateway layer, while using gRPC for type-safe, low-latency inter-service communication.
Core Components:
- API Gateway (Go): Built with Gin/Fiber or standard lib. Handles Auth, Rate Limiting, and transforms JSON HTTP/1.1 to internal gRPC.
- Protobuf Registry: Central source of truth for service contracts.
- Microservices (Go): Small, focused binaries running business logic.
- Consul/Etcd: Service discovery (if not using K8s native DNS).
