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.

Implementing Mesos and Marathon with DCOS


In Chapter 7, Scale Microservices with Spring Cloud Components, we discussed Eureka and Zuul for achieving load balancing. With container orchestration tools, load balancing and DNS services come out of the box and are much more simple to use. However, when developers need code-level control for load balancing and traffic routing, such as the business parameter based scaling scenarios mentioned earlier, Spring Cloud components may fit better.

Note

In order to understand the technologies better, we will use Mesos and Marathon directly in this chapter. However, in all practical scenarios, it is better to go with Mesosphere DCOS rather than playing with plain vanilla Mesos and Marathon.

DCOS offers a number of supporting components on and above plain Mesos and Marathon to manage enterprise-scale deployments.

Note

The DCOS architecture is well explained in the following link:https://dcos.io/docs/1.9/overview/architecture
