This document provides an overview of AppZero's application virtualization software. AppZero encapsulates applications into Virtual Application Appliances (VAAs) that can be instantly deployed and run without installation on any machine. The document discusses how AppZero works, including how it isolates applications from the underlying OS, and how VAAs can be deployed, run, and managed through tools like the AppZero Creator, Administrative Console, and Command Line Interface. It also summarizes key capabilities like lightweight intercept technology and establishing an application's context within a VAA.
