[IMAGE]Virtualization is taking over the datacenter at all levels. Organizations are greening their datacenters by transforming physical servers into virtual machines, but there is no better return on their investment than with application virtualization (AppV).
The reason is because applications, especially the ones that are distributed to PCs, represent the single biggest problem organizations must deal with. Application lifecycle management (ALM) is the most resource-intensive undertaking for many organizations, with issues such as conflict management, DLL hell, application patching, application deployment and remote installation among the chief concerns.[IMAGE]
Preparing a simple application for deployment can take from one to 10 days, depending on its complexity. When you have more than 300 applications to manage, this takes considerable effort. What if you could just make it go away?
Well this is the promise of app virtualization. It captures the "running state" of an application, not its installation, and it's this running state that is delivered to the desktop, not a Windows Installer-based installation.
The components of application virtualization
What makes application virtualization tick? In a perfect world, your AppV implementation would include the following components:
Overall, the application virtualization process should make it easier for desktop administrators to manage the application lifecycle while providing a transparent experience to end users. AppV is redesigning the application lifecycle management process (see Figure 1).

With AppV, the entire application lifecycle is simplified.
- First, you prepare the application for virtualization.
- Next, you move the newly virtualized application to a central repository. This repository is nothing more than a file share server.
- If you have remote sites, you replicate the repository to all remote sites where application deployment is required.
- Next, create a security group in Active Directory to assign the application.
- Because the application is assigned through Active Directory groups, you have complete license control at all times.
- The application is streamed to the appropriate desktop.
- The streamed application is stored in a local cache. Users can "take it away" with them when they need to.
That's it in a ...

nutshell. No need for complex software deployment infrastructures or installation processes. And you don't need to concern yourself with heavily staffed help desks to support new application deployments. With so many benefits, application virtualization is definitely worth looking into.... it's worth its weight in gold in today's datacenter.
