Chapter 1. Introduction to gRPC
Modern software applications rarely operate in isolation. Rather, they are connected with each other through computer networks and communicate and coordinate their actions by passing messages to one another. Therefore, a modern software system is a collection of distributed software applications that are running at different network locations and communicate with each other with message passing using different communication protocols. For example, an online retail software system comprises multiple distributed applications such as an order management application, catalog application, databases, and so on. To implement the business functionalities of an online retail system, it is required to have interconnectivity between those distributed applications.

Microservices Architecture
Microservices architecture is about building a software application as a collection of independent, autonomous (developed, deployed, and scaled independently), business capability–oriented, and loosely coupled services.1
With the advent of microservices architecture and cloud native architecture, conventional software applications that are built for multiple business capabilities are further segregated into a collection of fine-grained, autonomous, and business capability–oriented entities known as microservices. Therefore, a microservices-based software system also requires the microservices to be connected through the network using inter-process (or inter-service ...
