Government-as-a-Platform (?)

Forbes magazine published a short piece on how the some agencies in the Federal Government are turning to Cloud Computing to increase efficiency and enable better data sharing between agencies.  The article used a new-to-me term, Government-as-a-Platform, to describe federal agencies' cloud adoption.  I am all in for something that makes better use of our tax dollars, I just hope that governmental agencies think lean when implementing cloud solutions and demonstrate responsibility when spending our money.
