Bandwidth is about 2 orders of magnitude less on non-cloud even without any negotiation or commitment. How much do you have to commit for e.g. Cloudfront to pay 2 orders of magnitude less than their list price of 0.02 per GB?

To give you ballpark I colo metal servers at a few different data centers. A gig up is a few hundred dollars a month.

Let's say you're really pushing the connection and your p95 is 900megabit up. That is $200 at colo vs ~$8200 for amazon.
