Since it's well established now, I'd be surprised if Amazon EC2 is still profitable... Digital Ocean could be, but only because of the excessive amt of free credits they like to throw around
I know over on the MemoryCoin forum they have a setup for running it from Amazon as well as Digital Ocean.

yeah, I had around 50 servers running yam on protoshares until the feb 28 midnight thing.
well, they're still doing protoshares, but that's just 'cause i'm lazy. memorycoins would be better..
oh.. i started running bitcoind again on 3 of them just for kicks. i wish blockchain would connect to them more often
ed: oh, for a while there protoshares were even good to use with those Amazon EC2 7c 8 core instances
