Introduction to GRPC

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 enables the seamless communication between various tech stacks and systems. This is the integral concept of distributed computing.

Square, Netflix, and so on leverage this GRPC to scale their huge traffic-prone services. Google's former product manager...
