Even with the move to cloud services there are still businesses and situations where a local server is still the best solution. In many cases it is not a simple either /or but a hybrid solution with some services moved to the cloud and others being hosted on a local server.

Using Virtualisation techniques it is possible to consolidate multiple physical servers onto one physical box with savings in space and power consumption as well as allowing more efficient use of computing resources.  Virtualisation also allows more flexible backup and disaster recovery solutions with entire running machines being replicated to a remote backup location virtually in real time.
