This lack of definition isnt all that unusual. As the market for utility computing continues to grow, it will, to a certain degree, define itself. In my last column, I talked about Microsofts approach to defining a specific segment of the utility computing market as "high-performance computing."
With a market as broad as the potential utility computing market, it is likely that we will continue to see vendors split into two camps: those that want to define the market along their own product lines, and those who band together to chant the "open standards" mantra. Both camps will have their adherents among consumers, and it is likely that both will also grow and develop within the general utility computing marketplace.
Along with dedicated vendor marketing we will also see the rise of industry groups dedicated to defining the utility computing market and that will attempt to provide some direction and collaboration between otherwise disparate players in the utility computing space. One such group is the Enterprise Grid Alliance, which, in its own words, is a consortium formed to develop enterprise grid solutions and accelerate the deployment of grid computing in the enterprise. Current membership includes what could be described as the usual suspect: vendors such as EMC, Sun Microsystems, HP, Intel and Cisco. But unlike many industry/vendor organizations, EGA is also reaching out to the end-user community, offering a mechanism by which the average corporate user can sign up to be kept in the loop as to the organizations activities.
This effort is just getting started (and links to the end-user community can be found on the Web site) and is, in my opinion, an excellent idea. There is a tendency for these organizations to devolve into support for very narrow standards as defined by the vendor members, so additional information and feedback from an active user community can help keep attention focused on broader standards than those currently offered by participating vendors. The more players involved in a project like the EGA, the greater the ability to avoid tunnel vision and keep all the participants aware that they need to play well with others to be successful.
