In an effort to further commoditize computing, Sun is now selling
computing and storage utilities, modeled after other "grids" like electrical, water, and oil distribution. Instead of paying by the kilowatt-hour or gallon/litre, customers pay by the CPU-hour or the gigabyte-month.In a way, this is a natural extention of other hosting services, such as web hosting, except that general computational workloads are supported on many processors.
