As someone who has no idea about the cost of high-scale computing like this, is $150/hr reasonable? It seems like an amount that's hard to sustain to me, but I have no idea if that's a steady, all the time rate, or a burst rate, or what. Or if it's a set up you'd actually ever even need -- seems like from the examples they mention (like the Tweets), they're above the need by a fair amount. Anyone else in this sort of situation care to chip in on that?
