Virtualization
Virtualization
First introduced in the 1960s to allow partitioning of mainframe hardware, Virtualization has been a mainstay of high-end proprietary server environments ever since. Today, virtualization is once again a hot topic in the data center because several emerging virtualization technologies have the potential to improve resource utilization, efficiency, scalability and manageability for commodity hardware systems.
Opensource technologies such as Xen and KVM increase server utilization by consolidating physical servers and applications, thus lowering hardware, maintenance and electrical costs
Increase business continuity and system uptime by migrating disparate workloads onto virtual machines without interruption. Leverage excess data center capacity and improve response times by balancing computing loads across data center resources at peak times Customers can migrate server workloads to virtual farms and release physical resources that can be redeployed for other use
