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.

You should now have a feel for how to build and unit test any of the microservices in the Stock Trader application. You should also now be comfortable with how to containerize such microservices, and then run such containers and invoke such microservices.

Note that, often, rather than running such build steps as we've covered in this chapter manually from Command Prompt, you will have a DevOps pipeline that runs such steps for you, such as automatically kicking off via a webhook when you commit a change to your Git repository. For example, see this blog entry on such a CI/CD pipeline for the Trader microservice, which also performs various security and compliance checks: But it's good to understand how to do stuff manually, rather than it just seeming like some magical, mysterious thing occurs to get to where your container image is built and available in your image registry...
