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.

What are containers?


Containers are not revolutionary groundbreaking concepts. It has been in action for quite a while. However, the world is witnessing the reentry of containers, mainly due to the wide adoption of cloud computing. The shortcomings of traditional virtual machines in the cloud computing space has also accelerated the use of containers. Container providers, such as Docker, simplified container technologies to a great extent, which also helped the large adoption of container technologies in today's world. The recent popularity of DevOps and microservices also acted as catalysts for the rebirth of container technologies.

So, what are containers? Containers provide private spaces on top of the operating system. This technique is also called operating system virtualization. In this approach, the kernel of the operating system provides isolated virtual spaces. Each of these virtual spaces are called containers or virtual engines (VEs). Containers allow processes to run on an isolated...
