As in: running a full node on that instance?
What about bandwidth / number of connections? I vaguely remember some recommendations
not to bother with running a full node unless meeting certain requirements wrt the previous two variables, since otherwise you're not really adding much to the network. Is that a problem with the EC2 node?
If not, I'm going to start running a few of those instances as well. The reason for me not to permanently run a full node is that I don't have a machine that I don't use otherwise, and that I don't mind being dedicated to the network. But outsourcing it sounds exactly like my kind of deal

Please give us a rundown on how to set one up over there, at some point.
AWS has bandwidth and connections out the wazoo. You pay for it though but my quick calculations put it pretty low. It could get pricey if someone tried to get the whole blockchain from you but I understand that has been somewhat fixed. In theory, I could make an image of my node and put it out in the marketplace so anyone could use it but there would be a few things I'd have to do before I was comfortable doing that.
I should have written 8333 BTW. I'll go back and correct it.
