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.

Documenting cloud native applications using MicroProfile OpenAPI

As mentioned in Chapter 2, How Does MicroProfile Fit into Cloud-Native Applications?, you might have difficulties remembering what functionalities a particular cloud-native application has when you have tens or hundreds of cloud-native applications to manage. You will need to provide documentation for them. With documented endpoints, some clients can discover and invoke them.

MicroProfile OpenAPI (source code at provides a set of annotations and programming models that enable you to document cloud-native applications and then produce documents conforming to the OpenAPI v3 specification ( The OpenAPI v3 specification defines a set of interfaces for documenting and exposing RESTful APIs. MicroProfile OpenAPI adopts the OpenAPI Specification and further simplifies the OpenAPI model so that it is much easier for Java developers...
