You think amzn pays zero for inter-AZ transfer costs over fiber/whatever they don't own?

Some of the traffic doesn't leave the server, let alone the server rack.

I'd wager these costs have zero to do with operational or infrastructure costs, and are just a way to price gouge customers.

The stated purpose of AZ (the A stands for "availability") would suggest that this is not true. If AWS is running AZ foo and bar on the same server rack, then they're not being honest about what an AZ is. I'm not saying that's impossible, but that if they lying about this, that's a bigger problem.

Maybe? The whole thing with running large parts of the internet is that no one can refuse to carry your traffic, and you are able to dictate very favorable conditions.

(Also, whatever they pay, it is not charged in GB-increments.)

They have to pay for fiber running across data centers, the connection costs, switches, etc. It's definitely not free and no the conditions aren't favorable. In a lot of places there's a monopoly on who owns the fiber etc.
