Practical Cloud-Native Java Development with MicroProfile

By: Emily Jiang, Andrew McCright, John Alcorn, David Chan, Alasdair Nottingham

Overview of this book

In this cloud-native era, most applications are deployed in a cloud environment that is public, private, or a combination of both. To ensure that your application performs well in the cloud, you need to build an application that is cloud native. MicroProfile is one of the most popular frameworks for building cloud-native applications, and fits well with Kubernetes. As an open standard technology, MicroProfile helps improve application portability across all of MicroProfile's implementations. Practical Cloud-Native Java Development with MicroProfile is a comprehensive guide that helps you explore the advanced features and use cases of a variety of Jakarta and MicroProfile specifications. You'll start by learning how to develop a real-world stock trader application, and then move on to enhancing the application and adding day-2 operation considerations. You'll gradually advance to packaging and deploying the application. The book demonstrates the complete process of development through to deployment and concludes by showing you how to monitor the application's performance in the cloud. By the end of this book, you will master MicroProfile's latest features and be able to build fast and efficient cloud-native applications.

Technical requirements

To build and run the samples mentioned in this chapter, you will need a Mac or PC (Windows or Linux) with the following software:

  • Java Development Kit, version 8 or higher: https://adoptium.net/
  • Apache Maven: https://maven.apache.org/
  • A Git client: https://git-scm.com/

All the source code used in this chapter is available on GitHub at

Once you have cloned the GitHub repository, you can start the Open Liberty server that these code samples will execute in, by entering the ch6 directory and entering the following command from the command line:

mvn clean package liberty:run

You can then stop the server in the same command window by pressing Ctrl + C.

The application that's deployed to the Open Liberty server will be given a context root of ch6. For example, the full URL to a JAX-RS resource would be http://localhost:9080/ch6/path/to/resource. This will be reflected in the code samples in this chapter that illustrate sending...
