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.

In this chapter, we have learned about MicroProfile Config, which enables you to externalize your configuration to achieve a flexible and efficient cloud-native architecture, which is also highly recommended by the twelve-factor app.

We then went forward to explore how to create a resilient cloud-native application using MicroProfile Fault Tolerance so that application developers can concentrate on their business logic, where MicroProfile Fault Tolerance handles possible failures and then performs retries or limits resource consumption, and so on, via simple Fault Tolerance annotations.

After we covered Fault Tolerance, we then dived into MicroProfile OpenAPI to learn how to document your cloud-native applications using MicroProfile OpenAPI. We discussed a few ways to generate OpenAPI documents. Some MicroProfile OpenAPI implementation, such as Open Liberty, also provides UI integration for you to access endpoints directly via the UI.

Finally, we learned about the...
