Traditional Way: Pain Areas
o High Hardware Cost and Upgrade costo Power, cooling and space Requirementso Per PC maintenanceo Per PC software maintenanceo Low utilization of resources
• Not all PCs are always in use• Not 100% hardware resources are
consumed on each PCo User/PC provisioning is time consumingo Data residing on end user machine is prone to
leakageo No or limited control over data leakage by user
What do we want?
o Easy application provisioning to userso Zero application upgrade costo Zero end user managemento Better utilization of hardware and
software resourceso Centralized monitoring and
managemento Less power consumption less carbon
generationo Control over data leakage
Solution: Virtualization
o Separates applications/profile/Workspace from user’s OS
o Application Virtualization, “the hosting of individual applications on alien hardware/software”…wikipedia.org
Application Virtualization
o Application Virtualization via Terminal Services a.k.a. Presentation Virtualization (SERVER BASED COMPUTING)
• Application runs on Windows terminal servers. Users connects to the server via remote desktop protocols to interact with application GUI.
o Desktop Virtualization
• User’s physical machine is decoupled from the desktop and software he or she users to work. Desktop is delivered from a central data center.
o Application Streaming
• Application is not installed anywhere but is packaged to run under a specialized virtual environment when the package is executed by the user.
Method 1: Presentation Virtualization
PC, Laptop,Thin Client,

Presentation Virtualization: Limitations
o Shared System• Single point of failure
• Performance
o No per user/application resource hardware control
o Some applications are not terminal server friendly
o Display Performance: Multimedia applications
Method 3: DESKTOP VIRTUALIZATION
o Virtual desktops : Centralized Software based PCso Deliver desktops to users rather than provisioning
hardware to each usero Run hundreds and thousands of desktop OS
instances on centralized server running virtualization platform, like VMWare, XenServer, Parallels, VirtualBox
Windows XP 1 Windows XP 2 Windows XP 3

Desktop Virtualization: Benefits
o Highly Agile Desktopso Automated per PC maintenanceo Better hardware resource utilization
• Per user/application hardware resource control
o Better Data securityo Dynamic and automated application
provisioningo Reduced cost: hardware, power
