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.

Determining the health of your cloud-native application using MicroProfile Health

To begin our three-part journey of looking at the MicroProfile observability toolkit, we'll examine the MicroProfile Health technology. We chose to examine this technology first as its benefits and use cases are much broader in scope compared to the other two technologies in this chapter. The MicroProfile Health technology reports information regarding the health, or status, of your microservice. The expected health status is either UP or DOWN.

The importance of MicroProfile Health in a cloud-native application

We now know what the MicroProfile Health technology can do. But what purpose does it serve? To find out, we must take a step back. The driving force for developing applications with the MicroProfile technologies is that they will be cloud native. And if you recall Chapter 1, Cloud-Native Application, the important distinction between a cloud-native application and a non-cloud-native...
