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.

Instrumenting metrics on your cloud-native application using MicroProfile Metrics

This is the second part of our MicroProfile observability trilogy, where we find ourselves in the thick of things with MicroProfile Metrics. The previous technology we discussed – MicroProfile Health – strived to report on the overall health of your cloud-native application by allowing you, the developer, to strategically place health checks throughout your application. MicroProfile Metrics, on the other hand, strives to report on the performance and inner workings of the application and its environment using metrics instrumented in the application by you, as well as metrics provided by the MicroProfile Metrics runtime. This provides real-time statistics that can be recorded and/or aggregated to be analyzed with specialized monitoring tools. To accomplish this, the MicroProfile Metrics technology comes well-equipped with seven types of metrics that range in complexity and functionality....
