My experience is that the ops cost of a co-location facility are much more expensive than aws. The ops cost functions doesn't seem to linear as he is describing either. People costs dominate early on and are a huge factor until you start to reach steady state and that's the variable that you need to optimize for. Having said that aws is expensive. If dollars are worth more than hours to you, then yes, by all means host things yourself.
