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.

No more standards?

Having a number of tools that allow us to immediately take advantage of modern software architectures has made our life easier. These tools have emerged during recent years in order to deal with the problems that have to be solved when building systems consisting of a large number of ephemeral services distributed across the network. It has to be noted that, although we have chosen the proven solutions such as Hystrix or Keycloak, we have lost the mentioned portability and interoperability benefits of Java EE.

The problem was that the process in which the Java EE standard was being created wasn't able to keep up with the rapid pace of the development of the emerging technologies. The specifications that provide a common standard for solving problems associated with cloud architecture (for example, distributed security or network resilience) are not yet...
