The idea of IT as a service, provided as if it were electricity or water (with data integrity) seems to me to be very appealing to a part of the world that cannot and will not have the capex capacity required to leapfrog itself into the top ranks of the global economy.
But with cloud, maybe so. Just as asking, "what can electricity do?" sounds like a silly question from the Ben Franklin area, asking "what can cloud computing do?" is not the real question. The real question is, "how fast can cloud services be delivered to every corner of the world, and how?"
The electricity grids that span North America can, in theory, deliver juice from anywhere to anywhere, but given the pesky laws of electromagnetism and physics, it's best to keep the supply relatively close to the demand.
What about IT resources? Other than for real-time financial services markets, which fuss over latency issues in the microsecond range, how critical is location for the server farms that will power and empower Cloud Computing?
