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.

Cloud computing

OK. Let's start at the beginning. So, what actually is cloud computing?

Cloud computing is an IT paradigm that advocates the use of shared pools of configurable resources and services provided over the internet. Those services are provided on demand, rapidly, and with minimal management. As a result, cloud computing allows for flexible architecture, optimized resource usage, and the possibility of decoupling the infrastructure provider from a consumer, enabling the separation of concerns. Let's examine those statements in greater detail.

Resources provisioned on demand give you, as a developer or an architect, flexibility in configuring your technical infrastructure. Starting the project is cheap, as you don't have to begin with infrastructure investments. Also, when your project is in production, computing resources may be scaled automatically to...
