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 for BrownField microservices


In this section, the dockerized Brownfield microservices developed in Chapter 9, Containerizing Microservices with Docker, will be deployed into the AWS cloud, and we will manage them with Mesos and Marathon.

For demonstration purposes, we will cover only two services (search and website deployment) in this chapter. Also, we will use one EC2 instance for the sake of simplicity.

Installing Mesos, Marathon, and related components

Launch a t2.large EC2 instance with the Ubuntu 16.04 version AMI, which will be used for this deployment. In this example, we are using another instance to run RabbitMQ; however, this can be done on the same instance as well.

Perform the following steps to install Mesos and Marathon:

  • To install Mesos 1.2.0, follow the instructions documented in the following link. This will also install JDK 8:

  • To install Docker, perform the following steps:
sudo apt-get update
        sudo...
