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.

Plan the evolution


It is not simple to break an application that has millions of lines of code, especially if the code has complex dependencies. How do we break it? More importantly, where do we start, and how do we approach this problem?

Evolutionary approach

The best way to address this problem is to establish a transition plan, and gradually migrate the functions as microservices. At every step, a microservice will be created outside of the monolithic application, and traffic will be diverted to the new service as shown in the following diagram:

In order to run this migration successfully, a number of key questions need to be answered from the transition point of view:

  • Identification of microservices' boundaries

  • Prioritizing microservices for migration

  • Handling data synchronization during the transition phase

  • Handling user interface integration, working with old and new user interfaces

  • Handling of reference data in the new system

  • Testing strategy to ensure the business capabilities are intact...
