Advantages

  • Efficient Resource Utilization
  • Backward Compatibility
  • On-Demand Spike Absorption
  • Faster Recovery

Disadvantage

  • VM files are very large (order of gigabytes)!
  • VM Software is not free ☺

Lifecycle of a server VM

Loading Chambers Hibernation Nest Instantiated Disposed

  • 1. A large number of virtual servers

are stored as dormant files a SAN

  • r Netapps
  • 2. A number of virtual servers are

activated in a shared RM so that developers & system admins can upgrade, debug, or patch them.

  • 3. A virtual server is activated on a

dedicated RM and exposed to live load.

  • 4. A virtual server malfunctions

and is thrown away.
