It's taken me too long to realise that this really is just LXC or similar (OpenVZ), plus some nice directory service akin to JNDI. Analogy wise, a Linux version of a Java Application Server cluster? EAR or WAR files are not meant to contain their config, but look it up via JNDI lookups. They can be stopped/started/updated in place. They share common libs, and bring their own along with them. There are standard and vendor specific tools to monitor performance, provide messaging, manage resources, etc. etc. Edit: If that's what it is, I say HURRAH!!! because I've long felt that virtual machines were a failure in our ability to get the OS level design for dependency/config management "right".
