This architecture, such as VMware and Microsoft Virtualization redefines your computing equation by allowing for:
Many applications can run on each server. Each virtual machine can be an entire server or desktop, so one host can accommodate multiple operating systems to run at the same time.
Maximum server utilization, minimum server count. Every machine’s capacity is used in its entirety, allowing you to significantly reduce costs by deploying fewer servers overall.
Disaster Recovery (DR), Virtualization has changed disaster recovery making it less expensive and easier to implement for business of all sizes. Failover and failback times have gone from days to hours, even minutes in some cases.
