Utility Computing: Back to the Future
Concern for the bottom line is driving interest in utility computing, though the hype is still outstripping reality. But it's time to get readyby consolidating infrastructure and testing the pay-as-you-go waters with nonessential applications. Here'
The ROI for the utility computing model is a no-brainer. But not even the vendors pushing the concept think its ready for prime time.
IBM Corp. calls it "on demand computing." Hewlett-Packard Co. says that it goes hand in glove with its vision of the "adaptive enterprise." Computer Associates International Inc. has launched a fleet of systems that do nothing but map it, track it and bill for services rendered.
Whatever the label, the concept is compelling: the idea that companies could get rid of rows of back-room servers, legions of IT staffers, and all those expensive software upgrades in favor of a system that seems to require little more than plugging into an electric wall socket. Its called utility computing, and although, in concept, it has something in common with electricity, the reality is still a ways from catching up to the hype. Whats driving interest in the model is sheer economics: If enterprise applicationsalong with all the necessary hardware and people needed to make them workcould be paid for as needed, then corporations would stand to save untold millions of dollars they now spend each year to buy and maintain their underutilized equipment. And given the budgetary scrutiny every CIO faces these days, its no wonder the pay-only-for-what-you-use plan is looking so attractive.
Unfortunately, most experts say it may take as much as a decade before most computing chores become as easy to access as current from the local power plant. It may be unreasonable to expect that companies will ever be able to tap into every last piece of business functionality, perform every number-crunching computer task, track every customer shipment, and process every invoice using someone elses system not to mention someone elses IT staff.
