I'm not arguing that cloud is always the best option, but clearly there are many examples where profit per client far exceeds the cost per client. And btw, bandwidth is probably the simplest thing to calculate :) There are pros and cons with cloud, no doubt, but you seem to be ignoring the pros.

Anyway, on to the much more intereting question of misuse. I found these links interesting:

Seems like the answer is that you must deal with it yourself, or get cloudflare or similar to help you. I'm my limited experience, other most data centers / hosting providers charge for traffic, AWS etc. are just more expensive.

Edit: This is not "Denial Of Service Attack" btw, it's a "Bankrupt by Cloud Costs Attack" :D
