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 that focuses on Reactive Programming, you’ll be able to build modern, internet-scale Java applications in no time. The book starts off with guidelines to implement responsive microservices at scale. Next, you will understand how Spring Boot is used to deploy serverless autonomous services by removing the need to have a heavyweight application server. Later, you’ll learn how to go further by deploying your microservices to Docker and managing them with Mesos. By the end of the book, you will have gained more clarity on the implementation of microservices using Spring Framework and will be able to use them in internet-scale deployments through real-world examples.

Chapter 7. Scale Microservices with Spring Cloud Components

In order to manage Internet-scale microservices, one requires more capabilities than what is offered by the Spring Boot framework. The Spring Cloud project has a suite of purpose-built components to achieve these additional capabilities effortlessly.

This chapter will provide a deep insight into the various components of the Spring Cloud project, such as Eureka, Zuul, Ribbon, and Spring Config, by positioning them against the microservices capability model discussed in Chapter 4, Applying Microservices Concepts. This chapter will demonstrate how the Spring Cloud components help to scale the BrownField Airline’s PSS microservices system, developed in the previous chapter.

At the end of this chapter, we will have learned about the following:

  • The Spring Config Server for externalizing configuration
  • The Eureka Server for service registration and discovery
  • Understanding the relevance of Zuul as a service proxy and gateway
  • The implementation...
