Measuring that carbon footprint
I agree, Doug. The cartbon footprint of these modern, cloud data centers puts the enterprise data center to shame. One way of looking at it is that they tend to have a power unit efficiency of 1.1 vs. 2.0 for the enterprise. In the latter case, twice as much power is delivered to the data center as is actually used in computing. Plus think of all the trips to the Post Office that Facebook is eliminating. Think of all the trips to the store that Amazon.com is eliminating. Granted the delivery truck has to show up with the goods, but one truck making multiple stops in the neighborhood probably is more efficient than everyone traveling across town to the store. The N.Y. Times only scratched the surface of the impact of large data centers and came away knowing it didn't like them. I disagree.
