99% of Developers Don't Get gRPC

gRPC is a high-performance framework for communication between distributed systems using protocol buffers for binary serialization and HTTP/2 for transport. It supports four communication patterns: unary RPC, server streaming, client streaming, and bidirectional streaming. Compared to REST APIs, gRPC offers better efficiency through smaller message sizes, faster serialization, multiplexing, and type safety with automatic code generation. It's particularly suited for microservices architectures and backend-to-backend communication in distributed systems.
