Ah, it is indeed cheaper, but I'm getting different specific numbers: 240 cents/88 ecu-hr == 2.7 cents/ecu-hr on demand; less if reserved or spot. cc2.8xl is also in the Oregon and Ireland regions, but not others as far as I can tell.

1) Funny that scaling up to one of their largest instance types can improve bang-for-buck, on this metric at least. 2) I wish Amazon made it simpler to sort all this out.

Thanks for the check. I don't remember how I calculated that..

Another downside of cc2.8xl is that the spot market is crazy, with spikes at $6/h or more.
