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.

Deploying the application via the operator form UI

To deploy the application, we will follow these steps:

  1. Click on the View Operator button shown in Figure 9.10. You will be taken to a page showing you information about the operator, which of course looks very similar to what we saw when we first clicked on the operator in OperatorHub.

  2. We can use the Create Instance link shown in Figure 9.11 to launch into the dialog for installing an instance of our IBM Stock Trader application:

  3. Next, we will provide a Name for this instance.

    Note that you can use this operator to install as many instances as you want; for example, one instance might use a local DB2 database, and another might use a DB2aaS in the cloud. Each instance will use the Name you specify here as the prefix on all resources created; for example, if we type microprofile as the instance name...
