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.

Catalog service

In the first chapter, you learned the basic architecture of the pet store sample application and the services that constitute it. In this and the next chapter, we will be working with the catalog service. To recall, this is the service responsible for providing the information about pets available in the store. We are going to introduce that simple functionality now. In the next three chapters, we will modify that code in order to show you different features and configuration options of WildFly Swarm. Let's look at the initial version.

Draft version

We will start by introducing the first, draft version of the service, which we will examine and extend later.
