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.

Chapter 7: MicroProfile Ecosystem with Open Liberty, Docker, and Kubernetes

So far, in the previous chapters of this book, we focused on using the MicroProfile APIs to write a cloud-native application. In this chapter, we will look at how to run a cloud-native application. One of the features of MicroProfile that sets it apart from some other cloud-native application frameworks is that MicroProfile offers multiple implementations of the APIs. This reduces the chance of ending up locked into a particular implementation or finding that the open source community behind the APIs you were utilizing wasn't as vibrant as you thought and the maintainers disappear. In addition, different implementations tend to take different design decisions, which may better suit your needs. At the time of writing, there were four implementations of the most recent release of the MicroProfile APIs: Open Liberty, Payara, WebSphere Liberty, and WildFly. In addition, Helidon, JBoss EAP, KumuluzEE, and Quarkus...
