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.

Chapter 10. Scaling Dockerized Microservices with Mesos and Marathon

In order to leverage full power of a cloud-like environment, the dockerized microservice instances should also be capable of scaling out and shrinking automatically, based on the traffic patterns. However, this could lead to another problem. Once there are many microservices, it is not easy to manually manage thousands of dockerized microservices. It is essential to have an infrastructure abstraction layer and a strong container orchestration platform to successfully manage internet-scale dockerized microservice deployments.

This chapter will explain the basic scaling approaches and the need and use of Mesos and Marathon as an infrastructure-orchestration layer to achieve optimized resource usage in a cloud-like environment when deploying microservices at scale. This chapter will also provide a step-by-step approach to setting up Mesos and Marathon in a cloud environment. Finally, this chapter will demonstrate how to manage...
