Many companies are already starting to adopt new virtualization techniques in their IT assets. The benefit of virtualization is realized when several server roles are virtually consolidated on a single server hardware. This has the advantage of saving the cost of purchasing additional hardware to deploy certain network services.
The company will therefore be able to properly exploit the resources of its physical server, by installing several virtual machines on the same hardware. Each virtual computer uses the hardware resources that the administrator has assigned to it, and has its own name, address, and behaves completely independently of other machines, although they themselves are hosted on the same physical host. Client users, on the other hand, will not even be able to suspect that certain services are provided by a virtual machine, and will be able to work in total transparency.
Virtualization can also solve application compatibility problems. To this extent, business applications considered incompatible with new operating systems will be able to run perfectly on virtual machines running an inherited operating system.
Other uses of virtualization include providing customers with the ability to run a virtual server on the cloud, thus eliminating the cost of purchasing and maintaining a local server, similarly benefiting from permanent and off-site access to their applications and data, and taking advantage of high service availability, and high bandwidth.
