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.

Scaling microservices with Spring Cloud

In Chapter 5, Scaling Microservices with Spring Cloud, you learned how to scale Spring Boot microservices using Spring Cloud components. The two key concepts of Spring Cloud that we implemented are self-registration and self-discovery. These two capabilities enable automated microservices deployments. With self-registration, microservices can automatically advertise the service availability by registering service metadata to a central service registry as soon as the instances are ready to accept traffic. Once the microservices are registered, consumers can consume the newly registered services from the very next moment by discovering service instances using the registry service. Registry is at the heart of this automation.

This is quite different from the traditional clustering approach employed by the traditional JEE application servers. In the case of JEE application servers, the server instances' IP addresses are more or less statically configured...
