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.

Chapter 9: Deployment and Day 2 Operations

So far, we've seen many code snippets and screenshots of our example application, the IBM Stock Trader. Now, let's learn how to deploy it to your own OpenShift Container Platform cluster or any Kubernetes platform of your choice. As important as getting it running is, it is also very important to learn how to maintain it and tune it to meet your needs.

Unlike many Hello World samples that you might see on the internet, that either have no operator at all (just having you manually apply .yaml files to install), or they perhaps have a very simple operator per microservice, the IBM Stock Trader example has a composite operator that not only installs all of the microservices but also configures the connectivity to all prerequisite services, including all the credentials used for authentication.

This composite operator also provides an advanced form User Interface (UI) in the OpenShift console, used both at initial deployment time...
