Uncommon card · No. 163499

gRPC (recursive acronym for gRPC Remote Procedure Calls) is a cross-platform high-performance remote procedure call (RPC) framework. gRPC was initially created by Google, but is open source and is used in many organizations. Use cases range from microservices to the "last mile" of computing (mobile, web, and the Internet of things). gRPC 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. The most common usage scenarios include connecting services in a microservices style architecture, or connecting mobile device clients to backend services. gRPC's use of HTTP trailers makes it impossible to implement a gRPC client in a browser, instead requiring a proxy.
