Bottomline, nope. It's definitely not profitable to mine on AWS. :D (except maybe some of the low difficulty CPU mineable altcoins)
But if you have a mining rig running Linux (and ideally, AMD GPUs), then you can use these steps to get ethminer runnning on it (though, I know it's very trivial for anyone even semi-familiar with Linux).

I'm writing another article describing my experiments with mining on AWS instances. Wrote this so that I could keep that article short and to the point.
