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.

Twelve-Factor Apps


Cloud computing is one of the most rapidly evolving technologies. It promises many benefits, such as cost advantage, speed, agility, flexibility, and elasticity. There are many cloud providers offering different services. They are lowering the cost models to make it more attractive to the enterprises. Different cloud providers, such as AWS, Microsoft, Rackspace, IBM, Google, and so on, use different tools, technologies, and services. On the other hand, enterprises are aware of this evolving battlefield and, therefore, they are looking for options for de-risking from lockdown to a single vendor.

Many organizations do a lift and shift of their applications to cloud. In such cases, the applications may not realize all benefits promised by the cloud platforms. Some applications need to undergo an overhaul, whereas some may need minor tweaking before moving to the cloud. This is, by and large, depends upon how the application is architectured and developed.

For example, if the...
