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.

Converting a Monolithic App to a Microservice-Based App

We are at the last chapter of this book and I hope you have enjoyed and mastered the full stack microservice development (except databases). I have tried to touch upon all necessary topics to give you a complete overview of a microservice-based production application and allow you to move forward with more exploration. Since you have learned about microservice architecture and design, you can easily differentiate between a monolithic application and a microservice-based application, and you can identify what work you need to do to migrate a monolithic application to a microservice-based application.

In this chapter, we'll talk about refactoring a monolithic application to a microservice based application. I assume an existing monolithic application is already deployed and being used by customers. At the end of this chapter...
