What is gRPC?
gRPC is an open-source Remote Procedure Call, initially developed at Google in 2015. In 2017, it became a Cloud Native Computing Foundation (CNCF) incubation project due to increasing popularity.
The gRPC framework is used to build scalable and high-performance APIs. Many top organizations leverage it to power their user cases, from microservices to the web, mobile, and IoT.
It uses Protobuf (protocol buffer) as IDL (Interface Definition Language) to store data and function contracts in the form of a .proto file.
