What is grpc?
A modern open-source high-performance Remote Procedure Call (RPC) framework.
gRPC is a framework developed by Google to connect services with very high performance. It uses HTTP/2 for transport and Protocol Buffers (Protobuf) instead of JSON for data serialization. This makes it much faster and more efficient than traditional REST APIs.

gRPC is like a special, high-speed language that computers use to talk to each other. Instead of using a slow language like a long letter (JSON), they use a very short, coded language (Protobuf). It's much faster and they can send many messages back and forth at the same time over the same 'phone line' ([HTTP](/de/terms/http)/2).
🤓 Expert Deep Dive
gRPC features include bi-directional streaming, flow control, and automatic code generation for many languages. Because Protobuf is binary, the payloads are smaller than JSON, making gRPC ideal for internal 'East-West' traffic between microservices where latency must be kept at a minimum.
