Mastering Microservices with Java - Third Edition

By: Sourabh Sharma

Overview of this book

Microservices are key to designing scalable, easy-to-maintain applications. This latest edition of Mastering Microservices with Java, works on Java 11. It covers a wide range of exciting new developments in the world of microservices, including microservices patterns, interprocess communication with gRPC, and service orchestration. This book will help you understand how to implement microservice-based systems from scratch. You'll start off by understanding the core concepts and framework, before focusing on the high-level design of large software projects. You'll then use Spring Security to secure microservices and test them effectively using REST Java clients and other tools. You will also gain experience of using the Netflix OSS suite, comprising the API Gateway, service discovery and registration, and Circuit Breaker. Additionally, you'll be introduced to the best patterns, practices, and common principles of microservice design that will help you to understand how to troubleshoot and debug the issues faced during development. By the end of this book, you'll have learned how to build smaller, lighter, and faster services that can be implemented easily in a production environment.

Inter-Process Communication Using gRPC

gRPC enables client and server applications to communicate transparently, and makes it easier to build connected systems as per https://grpc.io. gRPC is an open source general-purpose Remote Procedure Call framework that was originally written by the Google engineers. In this chapter, we'll learn about gRPC and how to build services based on gRPC. Once some gRPC-based services are developed, which we'll refer to as gRPC servers, then we'll implement the gRPC-based client to establish the inter-process communication.


gRPC is pronounced as Jee-Arr-Pee-See.

In this chapter, we'll cover the following topics:

  • An overview of gRPC
  • The gRPC-based server
  • The gRPC-based client
