What is gRPC?
gRPC is a high performance, polyglot RPC protocol and framework built on HTTP/2 and Protocol Buffers. Designed for applications that are heavily dependent on RPC, gRPC provides superior performance to standard HTTP/REST calls and programmatically validated API contracts with Protocol Buffers.
Impact on Today
gRPC is increasingly popular as a common protocol for microservice communication due to its broad language support, API contracts, and performance. gRPC can also be extended to the web browser with the gRPC-Web protocol.
