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.

Setting Up the Development Environment

This chapter focuses on the development environment setup and configurations. If you are familiar with the tools and libraries, you could skip this chapter and continue with Chapter 3, Domain-Driven Design, where you could explore the domain-driven design (DDD).

This chapter will cover the following topics:

NetBeans IDE installation and setup
Spring Boot configuration
Sample REST program with Java 9 modules
Building setup
REST API testing using the Postman extension of Chrome

This book will use only the open source tools and frameworks for examples and code. This book will also use Java 9 as its programming language, and the application framework will be based on the Spring Framework. This book makes use of Spring Boot to develop microservices.

NetBeans' Integrated Development Environment (IDE) provides state of the art support for...
