Virtualisation is the process of partitioning the resources of one computer to allow it to run multiple workloads simultaneously. In its most fundamental form virtualisation serves to decouple a server’s operating systems from its physical hardware allowing a number of guest systems to run in parallel on the same hardware sharing processing, memory, storage and network resources. Virtual servers and virtual desktops let you host multiple operating systems and multiple applications both locally and in remote locations, freeing you from physical and geographical limitations. 

In addition to energy savings and lower capital expenses due to more efficient use of your hardware resources, you get high availability of resources, better desktop management, increased security, and improved disaster recovery processes when you build a virtual infrastructure.
