In what way does AppZero improve application independence compared to the more established VA/VM approach?

Unlike a virtual machine approach in which an application is installed on a VM, AppZero VAAs sit above the OS level and are unconcerned about different things like:

• Different hypervisors in place
• Processor architecture
• CPU core count
• Infrastructure such as storage configuration or technology
• Management frameworks and tolls for monitoring OS configuration and file versions
• Cloud technology

All of those concerns can be divorced away from the application.  So instead of moving a virtual machine and attempting to make it fit in a new environment, with AppZero you configure a machine – virtual or not – with all the infrastructure requirements and , using a VAA, simply move the app in on top of it.  This approach is a far simpler solution than configuring a system, trying to reconstruct an entire system or OS.  If you have ever tried to do this with a VM type migration, you understand the issues involved and how hard it can be to do.
