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, you'll be able to build modern, Internet-scale Java applications in no time. We would start off with the guidelines to implement responsive microservices at scale. We will then deep dive into Spring Boot, Spring Cloud, Docker, Mesos, and Marathon. Next you will understand how Spring Boot is used to deploy autonomous services, server-less by removing the need to have a heavy-weight application server. Later you will learn how to go further by deploying your microservices to Docker and manage it with Mesos. By the end of the book, you'll will gain more clarity on how to implement microservices using Spring Framework and use them in Internet-scale deployments through real-world examples.

Implementing Mesos and Marathon for BrownField microservices

In this section, the dockerized Brownfield microservice developed in Chapter 8, Containerizing Microservices with Docker, will be deployed into the AWS cloud and managed with Mesos and Marathon.

For the purposes of demonstration, only three of the services (Search, Search API Gateway, and Website) are covered in the explanations:

The logical architecture of the target state implementation is shown in the preceding diagram. The implementation uses multiple Mesos slaves to execute dockerized microservices with a single Mesos master. The Marathon scheduler component is used to schedule dockerized microservices. Dockerized microservices are hosted on the Docker Hub registry. Dockerized microservices are implemented using Spring Boot and Spring Cloud.

The following diagram shows the physical deployment architecture:

As shown in the preceding diagram, in this example, we will use four EC2 instances:

  • EC2-M1: This hosts the Mesos master, ZooKeeper...
