 Today’s x86 hardware is designed to run a single operating system and single application  Leaves most machines underutilized  Virtualization allows multiple virtual machines to run, using one physical machine, by sharing its resources  Different virtual machines can run different applications

 Use software to virtualize hardware of an x86 server (CPU, RAM, Hard Disk, Network Controller, etc.)  Installation of any Operating System to virtual machine  Hypervisor allocates resources from physical machine to virtual machines as needed

 Developed in 1960’s by IBM to partition large, mainframe hardware for better utilization  Abandoned in 1980’s and 90’s due to inexpensive client-server applications  Re-introduced in 1999 to deal with IT infrastructure operational challenges

 Low Infrastructure Utilization: Typical x86 platform only utilizes 10%-15% of server capabilities  Increasing Physical Costs: The cost to add an increasing amount of physical machines grew  Increasing Management Costs: As machines were added to an infrastructure management costs to monitor machines grew  Insufficient Disaster Recovery: Downtime critically affected important server applications

 60-80% utilization rates for x86 servers (up from 5-15% in non-virtualized PCs)  Cost savings of more than $3,000 annually for every workload virtualized  Ability to provision new applications in minutes instead of days or weeks  85% improvement in recovery time from unplanned downtime
