description gRPC Overview
gRPC is a high-performance, open-source framework that uses Protocol Buffers (Protobuf) for serialization. It is fundamentally different from REST because it defines services via strict Interface Definition Language (IDL) files. This forces extreme contract adherence and results in highly efficient, strongly typed communication, making it ideal for internal, high-throughput microservice communication.
