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.

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

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
