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.

Cloud computing has pioneered the distribution model for elastic, pay-as-you-go, on-demand IT hosted services. Any part of the IT delivered as a service is loosely covered under the broad theme of cloud computing.

Within the cloud computing theme, depending on the type of IT service, there are various terms for specific services of the cloud. Most of the terms are different variations of the term XaaS, where X is a placeholder that can be changed to represent multiple things.

Let's see the most common delivery models for cloud computing:

  • IaaS: When the computing resources (compute, network, and storage) are provided as a service to deploy and run operating systems and applications, it is termed as IaaS. If the organization does not want to invest in building data centers and buying servers and storage, this is a right choice of service to take advantage of. Amazon Web Services (AWS), Azure, and Google Cloud Platform (GCP) are leading examples of IaaS providers. In this model, you are responsible...
