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.

Deploying cloud-native applications to Open Liberty

In this section, we will look at how to deploy a MicroProfile application using Open Liberty. We have chosen Open Liberty because we are committers on Open Liberty, but its focus on being current with the latest releases of MicroProfile, performance, and ease of use make it a good option for anyone.

As you might expect from the name, Open Liberty is an open source Java runtime for building and deploying cloud-native applications. It is designed around the idea of components called features that can be configured to provide just enough runtime for your application needs. This means if your application doesn't use or need MicroProfile OpenTracing, then you don't need to configure the MicroProfile OpenTracing feature and the runtime will be smaller, faster, and leaner – it'll be better sized for what your application needs. Open Liberty has a feature for programming APIs such as MicroProfile APIs, Java EE, Jakarta...
