Hands-On Cloud Development with Wildfly

Create microservices using Java EE technologies with WildFly Swarm,deploy them in the OpenShift cloud, make them resilient to network failures using Hystrix, configure continuous integration using Jenkins, and security using Keycloak. 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 a microservice 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 fully functional example application and will have practical knowledge of Java EE cloud development that can be used as a reference in your other projects. If you're an experienced developer familiar with Java EE technologies and would like to learn how you can use those technologies in the cloud with WildFly and OpenShift, then this book is for you.
