Hands-On Cloud Development with WildFly

By: Tomasz Adamski

Overview of this book

The book starts by introducing you to WildFly Swarm—a tool that allows you to create runnable microservices from Java EE components. You’ll learn the basics of Swarm operation—creating microservices containing only the parts of enterprise runtime needed in a specific case. Later, you’ll learn how to configure and test those services. In order to deploy our services in the cloud, we’ll use OpenShift. You’ll get to know basic information on its architecture, features, and relationship to Docker and Kubernetes. Later, you’ll learn how to deploy and configure your services to run in the OpenShift cloud. In the last part of the book, you’ll see how to make your application production-ready. You’ll find out how to configure continuous integration for your services using Jenkins, make your application resistant to network failures using Hystrix, and how to secure them using Keycloak. By the end of the book, you’ll have a functional example application and will have practical knowledge of Java EE cloud development that can be used as a reference in your other projects.

Configuring Storage for Your Applications

In this chapter, we will start by learning the theoretical basis of OpenShift storage configuration. Later, we will show you how to deploy a database in the cloud and configure your cloud applications to use it.

In the last section of the preceding chapter, we deployed the simple version of CatalogService in the cloud, using OpenShift. We also got an initial feeling for the web console and OpenShift cli. Now, it is time to go further. We will reconfigure our application to use the database.

Before doing that, we will cover OpenShift persistence storage concepts.
