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.

Introducing WildFly

Most of you have probably heard about JBoss Application Server; WildFly is its successor. It is an open source implementation of the Java EE specification, and, more importantly in the context of this book, it is the base of Swarm project.

WildFly has an extensible architecture, which enables building differently sized distributions on top of its high-performance core, which, as we will learn in the next chapter, is utilized by Swarm to a great extent.


When you hear the phrase Java EE application server, the first thing that may come to your mind is the word heavyweight, as this is the way in which application servers are often described. It's worth noting however that the Java EE specification...
