Spring 5.0 Microservices - Second Edition

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.

Supporting capabilities


Supporting capabilities are not directly linked to microservices, but these are essential for large-scale microservices development. These services will have a dependency on the production runtime of microservices.

Service gateway

The Service gateway or API gateway provides a level of indirection by either proxying service endpoints or composing multiple service endpoints. The API gateway is also useful for policy enforcements and routing. The API gateway can also be used for real-time load balancing in some cases.

There are many API gateways available in the market. Spring Cloud Zuul, Mashery, Apigee, Kong, WSO2, and 3scale are some examples of the API gateway providers.

We will discuss the API gateway using Spring Cloud in Chapter 7, Scale Microservices with Spring Cloud Components.

Software-defined load balancer

The load balancer should be smart enough to understand the changes in the deployment topology and respond accordingly. This moves away from the traditional approach...
