This article explains why extending gRPC is necessary, outlines the go‑zero directory structure, describes how go‑zero adapts gRPC through a wrapper generated by goctl, and walks through service initialization and startup, highlighting metrics, etcd registration, interceptors, and health checks.
This article explores the fundamentals of load balancing in microservice architectures, detailing both stateless and stateful strategies such as round‑robin, random, hash, and weighted algorithms, and demonstrates how go‑zero and gRPC implement these mechanisms through custom balancers, service discovery, and request scheduling.
This article explains common service problems and presents practical solutions such as rate limiting, circuit breaking, and degradation, detailing their principles, implementation methods—including Nginx, token‑bucket, sliding‑window algorithms, and Go‑zero code examples—while highlighting key considerations for building resilient microservice systems.
go-zero, a CNCF‑listed cloud‑native web and RPC framework, offers a minimalist API definition tool (goctl) that generates client code for multiple platforms, and provides built‑in microservice governance features such as TLS, rate‑limiting, circuit‑breaking, and seamless integration, with the latest release adding TLS support for REST, ZRPC, Redis, etc.
