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.

Chapter 9. Platform Deployment – Azure

This chapter discusses application design and deployment for Azure—a Microsoft public cloud platform. The essence of cloud-native development is the ability to integrate your application with PaaS platforms provided by the cloud provider. You, as a developer, focus on creating value (solving customer problems), and allow the cloud provider to do the heavy lifting for your application's infrastructure.

In this chapter, we will learn the following:

  • Different categories of PaaS services provided by Azure. We will delve a little deeper into services that will be used by our sample applications.
  • Migrate our sample application to Azure and understand the various options available. We will also evaluate all the options and understand the pros and cons for each option.

We are covering the Azure platform with the intention of showing how to build and deploy applications. We are not going to cover Azure in depth, and we expect the reader to use the Azure documentation...
