Hands-On Cloud Development with WildFly

Turning an established Java EE application into a set of cloud-ready services involves more than packaging code: developers need to right-size runtimes, configure and test services, deploy them, and plan for security and resilience. Hands-On Cloud Development with WildFly traces that work through a practical example, using WildFly Swarm and OpenShift as its central tools.

Build services with WildFly Swarm

The book introduces Java EE and microservice architecture before moving into WildFly Swarm. From there, it explores how to shape a service around the runtime components it needs, work with Swarm configuration, and test services using Arquillian. The progression keeps the focus on the decisions involved in turning familiar enterprise Java components into independently runnable services.

Take the application into OpenShift

OpenShift deployment is set in context with coverage of cloud models, containers, Docker, and Kubernetes. Practical topics include storage and persistent volumes, scaling, load balancing, and service discovery. Together, these subjects show how an application’s individual services connect to the platform resources and operational patterns around them.

Address the work beyond deployment

The later material takes up continuous integration and deployment with Jenkins, application security with Keycloak, and resilience with Hystrix. These chapters extend the example beyond simply getting a service running, toward the supporting practices used to manage and protect a cloud-based application.

For Java EE developers exploring cloud development

This book is aimed at developers who already know Java EE and want to apply it with WildFly and OpenShift. The author assumes familiarity with Java EE rather than teaching its constructs from scratch, so readers can focus on how the technologies work together in a cloud-development workflow.

For a grounded look at Java EE microservices—from initial service design through deployment and production concerns—Adamski’s book offers a structured path through the tools and decisions involved.
