Virtualization

Virtualization

1. Application

   • insulate running programs from the underlying desktop
   • virtualization layer inserted between the app and the OS
   • Benefits
     • Allows the running of legacy apps
     • Enables cross-platform operations
     • Prevents conflicts with other virtualized apps
     • Permits users to run multiple app instances
   • Application virtualization transfers less data, thus lowering the impact on the hardware
   • Cost-effective

2. Desktop

   • method of simulating a user workstation
   • typically execute on virtual machines
   • Benefits
     • resources are pooled for efficiency
     • ability to access their business applications virtually anywhere there is internet connectivity
     • resources can be returned to centrally pooled infrastructure
   • Complete virtualization causes more impact on the underlying hardware
   • cost may be a concern
