What is gRPC ?
gRPC is an open source Remote Procedure Calls framework. As in many RPC systems, gRPC is based around the idea of defining a service and then specifying the methods that can be called remotely with their parameters and return types. On the server side, the server implements this interface and runs a gRPC server to handle client calls. On the client side, the client has a stub (referred to as just a client in some languages) that provides the same methods as the server. that can run in any environment. It can be used with several programming languages. It can connect services in and across data centers with pluggable support for load balancing, tracing, health checking and authentication. It is also applicable in last mile of distributed computing to connect devices, mobile applications and browsers to backend services.
gRPC clients and servers can run and talk to each other in a variety of environments - from servers inside Google to your own desktop - and can be written in many languages.
