gRPC (gRPC Remote Procedure Calls[2]) also known as Google Remote Procedure Call is an open source remote procedure call (RPC) system initially developed at Google in 2015 as the next generation of the RPC infrastructure, Stubby.[3][4] It uses HTTP/2 for transport, Protocol Buffers as the interface description language, and provides features such as authentication, bidirectional streaming and flow control, blocking or nonblocking bindings, and cancellation and timeouts. It generates cross-platform client and server bindings for many languages. Most common usage scenarios include connecting services in a microservices style architecture, or connecting mobile device clients to backend services.[4] gRPC's complex use of HTTP/2 makes it impossible to implement a gRPC client in the browser, instead requiring a proxy.[5]
