Cloud-Native Applications in Java

By: Andreas Olsson, Ajay Mahajan, Munish Kumar Gupta, Shyam Sundar S

Overview of this book

Businesses today are evolving so rapidly that they are resorting to the elasticity of the cloud to provide a platform to build and deploy their highly scalable applications. This means developers now are faced with the challenge of building build applications that are native to the cloud. For this, they need to be aware of the environment, tools, and resources they’re coding against. If you’re a Java developer who wants to build secure, resilient, robust, and scalable applications that are targeted for cloud-based deployment, this is the book for you. It will be your one stop guide to building cloud-native applications in Java Spring that are hosted in On-prem or cloud providers - AWS and Azure The book begins by explaining the driving factors for cloud adoption and shows you how cloud deployment is different from regular application deployment on a standard data centre. You will learn about design patterns specific to applications running in the cloud and find out how you can build a microservice in Java Spring using REST APIs You will then take a deep dive into the lifecycle of building, testing, and deploying applications with maximum automation to reduce the deployment cycle time. Gradually, you will move on to configuring the AWS and Azure platforms and working with their APIs to deploy your application. Finally, you’ll take a look at API design concerns and their best practices. You’ll also learn how to migrate an existing monolithic application into distributed cloud native applications. By the end, you will understand how to build and monitor a scalable, resilient, and robust cloud native application that is always available and fault tolerant.

Azure platform


Azure provides an ever-increasing set of PaaS and IaaS across a spectrum of technology areas. For our purpose, we will look at the subset of areas and services that are directly applicable and used by our application.

For ease of use, I have created this service categorization model across technology areas that are most relevant to typical business applications:

This is just an indicative list and by no means an exhaustive list. Refer to the Azure portal for a complete list.

In the preceding categorization models, we have divided the services into the following areas:

  • Infrastructure: This is an all-encompassing list of services provided by Azure to deploy and host our applications. We have combined services across compute, storage, and networking in this category. We will be looking at the following set of services for the purpose of our sample Java applications.
    • App Services: How can we take the existing Spring Boot applications and deploy them in our Azure platform? This is...
