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.

Do you need to migrate?

This is the first question that should set the tone for your migration. Do you really need to migrate your existing application to a microservice-based architecture? What benefits does it bring to the table? What are the consequences? How we can support the existing on-premise customers? Would existing customers support and bear the cost of migration to microservices? Do I need to write the code from scratch? How would the data be migrated to a new microservice-based system? What would be the timeline to this migration? Is existing team proficient enough to bring this change fast? Could we accept the new functional changes during this migration? Does our process in line to accommodate migration? So on and so forth. I believe there would be plenty of similar questions that come to your mind. I hope that, from all of the previous chapters, that you might...
