You may have some old applications running in production that your IT technical is afraid to touch. Server virtualization removes the application compatibility issue whereby you still run your old applications at the same environment but eventually they fit nicely to the latest server and hardware model.
Firstly, hardware replacement process is fast due to hardware dependency is no longer an issue. You no longer needs to keep identical hardware on hand to match the production environment. You can also automate the failover in the event of a disaster.
Most server virtualization platforms now offer capabilities such as live migration, storage migration, fault tolerance, high availability, and distributed resource scheduling, which just aren’t found on physical servers.
Server virtualization enables elastic capacity to system provisioning and deployment where you can quickly clone a gold image, master template, or existing virtual machine to get a server up and running within minutes.
Server virtualization abstracts away the underlying hardware and replaces it with virtual hardware, gain a lot more flexibility for server selection.
