I wasn't taking you as sarcastic, nor was I attempting snark in my reply: there are real costs either way, and it's our current judgement that learning how to do a virtualized, distributed stack would be more expensive than getting AWS to do it for us. (But, if I'm being honest, we haven't done any math)
And the < 10ms latency I'm talking about is between zones within us-east; latency to the west coast is a lot worse, but we only have emergency failover capacity in west.
