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.

Setting up your developer toolbox

For any profession, the tools are very important, and that applies to coding as well. Before writing a line of code, we need to get the right equipment to start.

Getting an IDE

An integrated development environment (IDE) is more than a code editor; it includes the tools for autocompletion, syntax, formatting, and other miscellaneous features, such as search and replace. IDEs have advanced features such as refactoring, building, testing, and running the programs with the help of runtime containers.

The popular IDEs are Eclipse, IntelliJ IDEA, and NetBeans. Of the three, Eclipse is the most popular and open source IDE available for Java. It has a big community and is frequently updated. It has a workspace and an extensible plugin system. The development potential of applications in a whole range of languages is endless. Some other development IDEs based on Eclipse include the following:

  • If you are going to do only Spring development, then the derivative of Eclipse...
