Mastering JBoss Enterprise Application Platform 7

By: Francesco Marchioni, Luigi Fugaro

Overview of this book

The JBoss Enterprise Application Platform (EAP) has been one of the most popular tools for Java developers to create modular, cloud-ready, and modern applications. It has achieved a reputation for architectural excellence and technical savvy, making it a solid and efficient environment for delivering your applications. The book will first introduce application server configuration and the management instruments that can be used to control the application server. Next, the focus will shift to enterprise solutions such as clustering, load balancing, and data caching; this will be the core of the book. We will also discuss services provided by the application server, such as database connectivity and logging. We focus on real-world example configurations and how to avoid common mistakes. Finally, we will implement the knowledge gained so far in terms of Docker containers and cloud availability using RedHat's OpenShift.

Preface

Chapter 13. Using EAP 7 with Docker

Today there is quite a buzz around the words Docker and containers. In short, Docker is a containerization engine that allows you to package up an application along with all the configuration and software required to run it and deploy it to a machine with the minimum of effort.

For some aspects, there are relevant advantages over a standard Virtual Machine (VM). As a matter of fact, a VM, takes up quite a lot of system resources as it embeds a virtual copy of all the hardware and software that the operating system needs to run. This requires a lot, in terms of RAM and CPU cycles.

On the other hand, container technology requires a minimal operating system, supporting libraries, and system resources to run a specific program. There is no doubt that starting a container is much faster than a Virtual Machine.

Another important characteristic of containers is that they are designed to be immutable in terms of library versions, configurations, and applications...
