Citrix XenServer is a complete, managed server virtualization platform built on the powerful Xen hypervisor. Xen technology is widely acknowledged as the fastest and most secure virtualization software in the industry. XenServer is designed for efficient management of Windows and Linux virtual servers and delivers cost-effective server consolidation and business continuity.

What is server virtualization?

Server virtualization is a proven technology that enables multiple virtual machines to run on a single physical server. Each virtual machine is completely isolated from other machines and is decoupled from the underlying host by a thin layer of software known as a hypervisor. This allows each virtual machine to run different operating systems and applications. Because the machines have been decoupled from the underlying host, the guest can also be moved from one physical server host to another while running, this is known as live migration. These attributes are transforming how organizations approach virtual computing.
