The goal of virtualization is to move from managing individual data center components to managing pools of resources. Server virtualization is important for successful server consolidation projects that require you to maintain the isolation of separate systems.
Successful server virtualization can lead to the following benefits:
Increasing the utilization of hardware
Enabling greater flexibility in resource allocation
Reducing data center power requirements
Minimizing management costs
Lowering the cost of ownership
Providing administrative and resource boundaries between applications on a system
Quickly provisioning virtual compute environments from templates and clones
Providing layered security and isolation
