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.

As we said before, in cloud computing, the cloud provider is responsible for providing the server resources to users on demand. However, what does that actually mean? How are those resources provided? How is the server with all the necessary configurations created, and how it is isolated from other users? To understand this, we must understand how containers work.

Containers are basically a type of virtualization. Let's discuss this concept.


Virtualization is a technology that allows the running of many isolated virtual machines on one server. A virtual machine is an emulation of a computer system governed by the virtualization application running on the server's operating system....
