The computing atmosphere
Economist on the geography of cloud computing. "One day soon, these 'virtual machines' may migrate to wherever computing power is cheapest, or energy is greenest. Then computing will have become a true utility--and it will no longer be apt to talk of computing clouds, so much as of a computing atmosphere."
More: "Local governments give tax breaks in the hope that the presence of big data centres will attract other businesses (the computing plants themselves usually employ only a few dozen people)."
