Some validation for grid computing in this New York Times article about IBM:
“All these advances — faster and faster processing, better systems administration tools and the maturity of software communications standards — have really turned utility computing into a much more doable proposition,” said Glen Salow, the chief information officer of the American Express Company. Earlier this year, American Express agreed to a seven-year computing-on-demand deal with I.B.M., after Mr. Salow became convinced that the pay-for-use, utility model would afford his company both reliability and cost-saving flexibility.
As Dave Farber and others have pointed out, the basic technology behind grid computing isn’t new… but neither was the basic Internet technology when Mosaic appeared. Grids becoming less interesting as basic science actually means they are ready to have a significant impact on business.
