Server consolidation continues to be one of the strongest drivers of virtualization adoption, and one of its most significant pay-offs. However, when it comes to provisioning server-based applications, AppZero's Virtual Application Appliance (VAA) approach offers dramatic benefits in agility, cost, and performance -- whether deploying to physical or virtual machines.
This paper examines the impact of application virtualization technology on overall system performance. It documents a simple performance evaluation of application virtualization using AppZero virtual application appliance (VAA) compared to a VMware ESXbased system using virtual machines (VM).
Both approaches were compared to simultaneously running multiple applications natively on a Windows-based server. A series of tests were run to look at the performance characteristics of the systems based on a simple Web-based test application.
The test quantitatively demonstrates AppZero VAA performance at near-native level. Equally effective in physical, virtual, and cloud environments, AppZero's instant server-side application provisioning is a natural complement to server virtualization - driving higher server density and consolidation.
