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.

Microservices to the rescue


There are not many improvement opportunities left to support the growing demand of BrownField Airline's business. BrownField Airline was looking to re-platform the system with an evolutionary approach rather than a revolutionary model.

Microservices is an ideal choice in these situations—for transforming a legacy monolithic application with minimal disruption to the business:

As shown in the preceding diagram, the objective is to move to a microservices-based architecture aligned to the business capabilities. Each microservice will hold the data store, the business logic, and the presentation layer.

The approach taken by BrownField Airline is to build a number of web portal applications targeting specific user communities such as customer facing, front office, and back office. The advantage of this approach lies in the flexibility for modeling, and also in the possibility to treat different communities differently. For example, the policies, architecture, and testing...
