Practical Cloud-Native Java Development with MicroProfile

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.

Overview of the IBM Stock Trader application

Created and enhanced over the past 3-4 years, this polyglot example demonstrates how to create containerized microservices, targeting a variety of application runtimes. For the most part, these microservices are deliberately kept simple so that readers don't get bogged down in the deep technical intricacies that would likely exist in a real brokerage application. That said, it is very much intended to be significantly more instructive than the various Hello World-level examples often shown in beginners' documentation for cloud-native programming.

The example consists of about a dozen microservices that interact with about a dozen external dependencies (most of which are optional). There is also a Helm chart and an OpenShift operator (which wraps the Helm chart) used for deployment of the example, which will be covered in Chapter 9, Deployment and Day 2 Operations.

In this section, we will provide a high-level overview of...
