Spring Microservices

Overview of this book

The Spring Framework is an application framework and inversion of the control container for the Java platform. The framework's core features can be used by any Java application, but there are extensions to build web applications on top of the Java EE platform. This book will help you implement the microservice architecture in Spring Framework, Spring Boot, and Spring Cloud. Written to the latest specifications of Spring, you'll be able to build modern, Internet-scale Java applications in no time. We would start off with the guidelines to implement responsive microservices at scale. We will then deep dive into Spring Boot, Spring Cloud, Docker, Mesos, and Marathon. Next you will understand how Spring Boot is used to deploy autonomous services, server-less by removing the need to have a heavy-weight application server. Later you will learn how to go further by deploying your microservices to Docker and manage it with Mesos. By the end of the book, you'll will gain more clarity on how to implement microservices using Spring Framework and use them in Internet-scale deployments through real-world examples.

Moving from traditional web applications to microservices

Carefully examining the preceding RESTful service will reveal whether this really constitutes a microservice. At first glance, the preceding RESTful service is a fully qualified interoperable REST/JSON service. However, it is not fully autonomous in nature. This is primarily because the service relies on an underlying application server or web container. In the preceding example, a war was explicitly created and deployed on a Tomcat server.

This is a traditional approach to developing RESTful services as a web application. However, from the microservices point of view, one needs a mechanism to develop services as executables, self-contained JAR files with an embedded HTTP listener.

Spring Boot is a tool that allows easy development of such kinds of services. Dropwizard and WildFly Swarm are alternate server-less RESTful stacks.
