This is an article in a series on Deployment.

Is it an image, is it a container? Bundling an entire application to be run isolated, perhaps a WAR file is a container avant la lettre. It allows JVM compiled applications to be run within a VM. This is not exclusive to applications written in Java, and might even include JRuby. Since it is atypical for Rails applications to be deployed this way, I am not considering it, but it might be an alternative for you.
