Late last year, Microsoft in the US published "The Economics of the Cloud", which I've only just got around to reading. If you are running a data centre in education - either at university or state level - then this is a good read to understand where your costs are adding up, and where you could be making savings. The document has some data points which were surprises for me (I love data points, so this report made my day):
With so many Cloud projects happening in education in Australia, I wonder if anybody is yet collecting the statistics for what's being saved - in power, space or dollar terms?
