Mastering Microservices with Java 9 - Second Edition

Overview of this book

Microservices are the next big thing in designing scalable, easy-to-maintain applications. They not only make app development easier, but also offer great flexibility to utilize various resources optimally. If you want to build an enterprise-ready implementation of the microservices architecture, then this is the book for you! Starting off by understanding the core concepts and framework, you will then focus on the high-level design of large software projects. You will gradually move on to setting up the development environment and configuring it before implementing continuous integration to deploy your microservice architecture. Using Spring security, you will secure microservices and test them effectively using REST Java clients and other tools like RxJava 2.0. We'll show you the best patterns, practices and common principles of microservice design and you'll learn to troubleshoot and debug the issues faced during development. We'll show you how to design and implement reactive microservices. Finally, we’ll show you how to migrate a monolithic application to microservices based application. By the end of the book, you will know how to build smaller, lighter, and faster services that can be implemented easily in a production environment.

Migrating a Monolithic Application to Microservice-Based Application

We are at the last chapter of this book and I hope you have enjoyed and mastered the full stack (except DB) microservice development. I have tried to touch upon all necessary topics that will give you a complete view 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 one needs 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...
