Virtualization is a Type of Cloud Computing. Hypervisors are the software that Operating System "Instances" run on. Overview Virtualization allows you to easily migrate servers between pieces of physical hardware Virtualization allows you to consolidate multiple cheap physical servers into one server An "Instance" is a "Virtual Computer" installed on a Hypervisor. Type 1 Hypervisors Called Bare Metal Hypervisor Installs directly on to hardware You use Management Software installed on a different computer to manage a Type 1 Hypervisor box. Based on XEN. Generally the Hypervisor is free, but you pay for the Management software Over Allocation allows you to allocate more total resources to the Instances of the operating systems then the physical server has. At any one time all Instances CANNOT use more resources then the total amout that the <b>…</b>
