About gRPC

gRPC (gRPC Remote Procedure Calls) is an open-source high-performance framework that can run in any environment. It is initially developed at Google in 2015 as the next generation of the RPC infrastructure. It uses HTTP/2 for transport, Protocol Buffers as the interface description language.

The main benefits of gRPC are:

  • Modern, high-performance, lightweight RPC framework.
  • Contract-first API development, using Protocol Buffers by default, allowing for language-agnostic implementations.
  • Tooling is available for many languages to generate strongly-typed servers and clients.
  • Supports client, server, and bi-directional streaming calls.
  • Reduced network usage with Protobuf binary serialization.
