Virtual IT systems give you many benefits, when compared to traditional IT systems.
With a traditional IT system you are responsible for the support of the system, even if it is outsourced to an external IT company.
With a hosted desktop system, because your servers and applications are housed in data centres, your main IT system is already being fully managed and supported by a dedicated IT support team, which, not only gives you peace of mind, but also the satisfaction that your costs are scaleable and fixed, compared with a traditonal IT system.
