GRPC is a transport mechanism that sends and receives messages between two systems. These two systems are traditionally a server and a client. As we described in the previous chapters, RPC can be implemented in Go for transferring JSON. We called it a JSON RPC service. Similarly, Google RPC is specially designed to transfer data in the form of protocol buffers.
GRPC makes the service creation easy and elegant. It provides a nice set of APIs to define services and start running them. In this section, we will mainly focus on how to create a GRPC service and use it. The main advantage of GRPC is that it can be understood by multiple programming languages. Protocol buffers provide a common data structure. So, the combination ...
