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.

Building your own platform services (control versus delegation)

Another key decision for enterprises is how to choose your platform:

  • Should I be building my own platform?
  • Should I subscribe to an existing platform and develop my application on top of it?

This decision boils down to the factor how do you see technology, as an enabler (control) or a differentiator (delegation)?

At the core, all companies are technology companies. But the question is whether controlling technology provides you with the additional edge over your competition, or helps build a moat that can potentially discourage new players from coming. Let's take a couple of examples and see how it plays out:

  • If you are to planning to compete with a company such as Amazon in the retail space, you need to have deep pockets. The low margin business of Amazon retails is bankrolled by profitable business from AWS. So, unless you have a sugar daddy or alternate revenue models, competing with Amazon is not going to be easy. But assuming...
