However, where maximising consolidation, availability and agility are of paramount importance, a combination of server virtualisation and grid-based solutions are the best way to maximise the benefits of consolidation, availability and agility. Working in tandem, they can ensure enhanced server virtualisation, the ability to dynamically scale within and across nodes, and the dynamic resizing of virtual nodes. Compared to other models of computing, IT systems designed and implemented in the grid style deliver a higher quality of service, at a lower cost, with greater flexibility.
