Server virtualisation dramatically reduces the number of physical servers in an organisation by enabling multiple ‘virtual servers’ to be run on a single or reduced number of shared machines. Each virtual server has its own operating system, applications will run as normal, and users have access via the network as usual. Multiple virtual servers are managed via a single management layer, or ‘hypervisor’.
