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.

Making a cloud application resilient using MicroProfile Fault tolerance

Why do you need to care about resilience? For mission-critical applications, a very brief downtime might cause you a huge penalty. Besides, your customer satisfaction will decrease if your applications are too fragile and aren't resilient. Therefore, you should consider building resilient applications, which means they will function under all kinds of situations with zero downtime. MicroProfile Fault Tolerance (source code at introduces several resilience policies that can help you build a resilient application. These policies can be applied to CDI beans. It also provides a way to execute method invocations asynchronously via the annotation @Asynchronous.


The annotation @Asynchronous can be placed on a CDI bean class or the methods of a CDI bean class. If placed on a class, it means all of the methods declared on this class will...
