7. Better testing
Virtualization makes easier the development and test of new application: thanks to up-to-date snapshots a tragic mistake can be solved turning back to the previous environment without any kind of loss. The risk of testing is dramatically reduced and you have more benefits, for example the opportunity to isolate the testing environment.
8. No vendor lock-in
Another benefit is that you don’t have any vendor lock-in. Virtualization implies an abstraction between hardware and server that means no lock-in in the usage of a particular kind of server, or even of a specific server model, with the maximum flexibility not available in a physical environment.
