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.

Tracing your cloud-native application using MicroProfile OpenTracing

We will conclude our MicroProfile observability journey by looking at the MicroProfile OpenTracing technology. Unlike the other two technologies we've examined in this chapter, MicroProfile OpenTracing is much more lightweight in comparison. We'll cover the importance of this technology while overviewing it and jump straight into learning how to use MicroProfile OpenTracing.

The importance of and an overview of MicroProfile OpenTracing in a cloud-native application

The MicroProfile OpenTracing technology ties in with the concept of distributed tracing. In a cloud environment, applications or microservices communicate and interact with one another, which, in turn, can interact with other microservices. This chain of interactions can be quite lengthy, depending on the nature and context of your application deployments. When something unexpectantly fails, it can be a difficult and troublesome task to...
