Hands-On Cloud Development with WildFly

Create microservices using Java EE technologies using 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.

Key Features

• Create functional microservices with WildFly Swarm
• Use OpenShift to deploy your microservices in the cloud
• Make your application production-ready using Jenkins, Hystrix, and Keycloak

Book Description

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.

What you will learn

• Utilize Java EE technology to develop modern cloud-enabled applications
• Easily create microservices with WildFly Swarm using proven Java EE technologies
• See the benefits of OpenShift – easy deployment of your services, out of the box scalability and healing, and integration with Continuous Integration tools
• Integrate the sample application with Jenkins’ Continuous Integration server
• Utilize Hystrix to provide resilience? to your application
• Provide security to your application using Keycloak
