Great article, but just when I thinking of IaaS and SaaS, actually are we IT professionals are digging our grave ? when services and infrastructures all move over, business actually can actually CUT OUT our existence in the company, and when users can easily config anything they want, which mean only 1 or 2 IT staffs would be more than enough... what about the rest of us ? go back to work as a clerk or work in other industries ?
