gRPC Has a Free API: High-Performance RPC Framework by Google

gRPC is a modern, high-performance RPC framework that uses Protocol Buffers and HTTP/2. It enables efficient communication between microservices with features like streaming, load balancing, and automatic code generation. What Is gRPC? gRPC (gRPC Remote Procedure Calls) is a CNCF incubating project originally developed by Google. It uses Protocol Buffers for serialization (10x smaller than JSON) and HTTP/2 for transport (multiplexing, header compression). Key Features: Protocol Buffers (protobuf) serialization HTTP/2 transport (multiplexing, streaming) Bidirectional streaming Code generation for 11+ languages Built-in authentication (TLS, token) Load balancing Deadline/timeout propagation Interceptors (middleware) Define Your Service // order.proto syntax = "proto3" ; package order ; service OrderService { rpc CreateOrder ( CreateOrderRequest ) returns ( Order ); rpc GetOrder ( GetOrderRequest ) returns ( Order ); rpc ListOrders ( ListOrdersRequest ) returns ( stream Order ); rpc Strea
