Overview of this book

Spring Framework has become the most popular framework for Java development. It not only simplifies software development but also improves developer productivity. This book covers effective ways to develop robust applications in Java using Spring. The course is up made of three modules, each one having a take-away relating to building end-to-end java applications. The first module takes the approach of learning Spring frameworks by building applications.You will learn to build APIs and integrate them with popular fraemworks suh as AngularJS, Spring WebFlux, and Spring Data. You will also learn to build microservices using Spring's support for Kotlin. You will learn about the Reactive paradigm in the Spring architecture using Project Reactor. In the second module, after getting hands-on with Spring, you will learn about the most popular tool in the Spring ecosystem-Spring Boot. You will learn to build applications with Spring Boot, bundle them, and deploy them on the cloud. After learning to build applications with Spring Boot, you will be able to use various tests that are an important part of application development. We also cover the important developer tools such as AMQP messaging, websockets, security, and more. This will give you a good functional understanding of scalable development in the Spring ecosystem with Spring Boot. In the third and final module, you will tackle the most important challenges in Java application development with Spring Boot using practical recipes. Including recipes for testing, deployment, monitoring, and securing your applications. This module will also address the functional and technical requirements for building enterprise applications. By the end of the course you will be comfortable with using Spring and Spring Boot to develop Java applications and will have mastered the intricacies of production-grade applications.

Chapter 16. Microservices with Spring Boot

@SpringBoot and @SpringCloudOSS are making it way too easy to build advanced distributed systems. Shame on you! #ComplimentarySarcasm

In the previous chapter, we learned how to communicate between different systems using AMQP messaging with RabbitMQ as our broker.

In this day and age, teams around the world are discovering that constantly tacking on more and more functionality is no longer effective after a certain point. Domains become blurred, coupling between various systems makes things resistant to change, and different teams are forced to hold more and more meetings to avoid breaking various parts of the system, sometimes, for the tiniest of changes.

Emerging from all this malaise are microservices. The term microservice is meant to connote a piece of software that doesn't attempt to solve too many problems, but a targeted situation instead. Its scope is microscopic when compared with the existing behemoth monoliths...
