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.

Summary

In this chapter, you learned a lot about OpenShift architecture. You were introduced to cloud computing and was provided the most essential information about it. Later, you learned about the architecture of OpenShift: a Kubernetes cluster using Docker images with an OpenShift layer, making cluster easy, to use and allowing developers to focus on coding.

Later in the chapter, you started your own local OpenShift instance using the Minishift tool and deployed your first service on it.

In the next chapter, you will learn how to configure persistent storage for microservices deployed in the cloud.
