Re: What took them so long?
A cloud implied leasing virtual equipment by the hour, the provision expanding and contracting per demand.
IBM ***had*** that sort of setup at one time (before such a thing was being called "cloud"). They shut it down in favor of what IBM was passing off as "cloud computing", much to the disgust of some soon-to-be EX-customers. IBM can be ahead of the trend and STILL miss out.
