In a prior post I argued that a lot of the work happening in your data center could probably be done someplace else. One of the counter arguments to this approach is the potential loss of the competitive advantage achieved by owning your compute resource, especially where your competition can not or does not own a parallel resource. There may be some situations where this is true, but in most situations external resources (ex: Cloud Computing) can actually liberate a business from the capital constraints of building a private compute center. If compute capacity delivers a competitive advantage, external availability provides scale to the limits of what an organization use. Like any other resource, the trick is in using it effectively. Ability to take advantage of this resource will be a future differentiator for compute enabled companies. One of my favorite sound bites was an estimate in "information week" stating that a one-millisecond advantage in trading applications could be worth $100 million a year to a major brokerage firm.
Taking advantage of the computing cloud starts to look a lot like the fabled utility computing architecture. Utility computing is real, but Gartner* still places it on decent into the "trough of disillusionment". I agree, and broad availability of utility computing is still a few years out. That doesn't mean IT managers should be waiting.
