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.

Approaches and keys to successful migration

Software modernization has been done for many years. A lot of work is done to perform successful software modernization. You will find it useful to go through all of the best practices and principles for successful software modernization (migration). In this chapter, we will talk specifically about software modernization of the microservice architecture.

Incremental migration

You should transform monolithic applications to microservices in an incremental manner. You should not start the full-fledged migration of the whole code all together. It entangles the risk-reward ratio and increases the probability of failure. It also increases the probability of transition time and, hence...
