Cloud-Native Applications in Java

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 12. Digital Transformation

The advent of cloud computing is impacting every facet of the enterprise landscape. From the core infrastructure to the client-facing applications, the enterprise landscape is seeing the impact of the forces of change. Some enterprises are the leading harbingers of these transformations, while others are still trying to figure out where to start and what to do. Depending upon the maturity of the industry domain, the transformation journey can be very different. Some domains are the first to adopt technology trends (such as BFSI), while others wait for technology obsolescence to adopt new technology (manufacturing, utilities). In this chapter, we will cover the following:

  • Mapping the application portfolio for digital transformation
  • Breaking an existing monolithic application into a distributed cloud-native application
  • Changes required at the process, people, and technology levels
  • Building your own platform services (control versus delegation)
