Spring 5.0 Microservices - Second Edition

By: Rajesh R V

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.

Preparing BrownField PSS services


In the previous section, we successfully set up Mesos and Marathon. In this section, we will see how to deploy the BrownField PSS application previously developed using Mesos and Marathon.

Note

The full source code of this chapter is available under the chapter10 projects in the code files under https://github.com/rajeshrv/Spring5Microservice. Copy chapter9.* into a new STS workspace and rename it chapter10.*.

In this example, we will force the Mesos cluster to bind to fixed ports, but, in an ideal world, we will delegate the Mesos cluster to dynamically bind services to ports. Also, since we are not using a DNS or HA Proxy, we will hardcode the IP addresses. In the real world, a VIP for each service will be defined, and that VIP will be used by the services. This VIP will be resolved by the DNS and Proxy.

Perform the following steps to change the BrownField application to run on AWS:

  1. Update search microservices (application.properties) to reflect the RabbitMQ...
