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.

Integration with third-party APIs

In the previous section, we saw the design concerns when building your own service provider. In this section, we will see how, if you are trying to build a consumer application, to take advantage of the REST services provided by third-party companies. For example, you are trying a build a beautiful mobile application, your core competency is building visual design and creating mobile applications. You do not want to get burdened with managing all the complexities that go with hosting/managing the application data. The application will require services that include storage, notifications, location, social integration, user management, chat functions, and analytics, among others. All these providers are bunched together under the umbrella of Backend as a Service (BaaS) providers. There is no need to sign up with a single vendor for these services; you can pick and choose which providers fit your business needs and budgets. Each of the providers typically runs...
