Executive Interview: IBM's Stuart Feldman On Grid Computing: Page 2 of 4

So, some of those standards are there: Web standards and Web services are there, and grid is the underlying mechanism for getting the job done.

IT Utility Pipeline: IBM talks a lot about on-demand computing. How does the Web and on-demand effectively intersect?

Feldman: On-demand has to offer end-to-end access so businesses can get the optimization they need. Web services and grid will promote end-to-end architecture and allow businesses to change how they act. The best way to get to this model is with grid and Web services running. The beauty of Web services and grid is that the user won't know this is the way the job is getting done. They will just be able to share services for efficiencies.

IT Utility Pipeline: When do you expect grid and on-demand to be mainstream?

Feldman: A real indication is when the adoption increases exponentially. We're seeing grid and Web services doubling but it is still under the radar. When we see it growing exponentially year over year, then we'll begin to see people take notice. I think it will be visible to the general person in three to five years. It is still young. It was visible to insiders last year.
