gRPC is the RPC framework of choice for performance-sensitive microservice communication and AI inference serving (Triton, TensorFlow Serving, etc.). Its protobuf serialization, HTTP/2 multiplexing, and bidirectional streaming make it faster and more efficient than REST/JSON for high-throughput service-to-service calls. Confidence is docs-derived.
The framework surface covers service definition in .proto files, code generation for clients and servers in all major languages, unary and streaming RPC patterns, and interceptors for auth/logging/metrics. gRPC-Gateway enables HTTP/JSON transcoding for clients that need REST.
Auth uses channel credentials (TLS) for transport security and call credentials (JWT, OAuth token) for request-level auth. gRPC metadata carries auth tokens equivalent to HTTP headers. mTLS is supported for mutual authentication.
Operationally, gRPC is highly efficient but requires proto schema management, code generation steps, and HTTP/2-aware infrastructure. Load balancers and proxies need gRPC support (L7 load balancing). Client-side load balancing is common for service meshes.
Documentation at grpc.io is thorough and covers quick starts, service definition, auth patterns, and streaming in all major languages. Developer experience requires accepting proto-first design discipline; the payoff is strong type safety across service boundaries.
