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.

Introduction to Docker


Previous sections talked about containers and their benefits. Containers have been present in the business for years, but the popularity of Docker has given containers a new outlook. As a result, many container definitions and perspectives have emerged from the Docker architecture. Docker is so popular, that even containerization is referred to as Dockerization.

Docker is a platform to build, ship, and run lightweight containers based on Linux kernels. Docker has a default support for Linux platforms. They also have support for Mac and Windows using Boot2Docker, which runs on top of Virtual Box.

Amazon EC2 Container Service (ECS) has out-of-the-box support for Docker on AWS EC2 instances. Docker can be installed on bare metals and also on traditional virtual machines such as VMWare or Hyper-V.

Key components of Docker

The Docker installation has two key components. A Docker daemon and a Docker client. Both, Docker daemon and Docker client are distributed as a single binary...
