This question may sound weird to some of you but I have never really used cloud and above all I'm still beginner in the web development and would be really thankful if someone could answer few of my question though they may sound weird

So I would like to deploy simple website to Amazon, however, I'm concerned about bandwidth as they charge 0.12GB and I'm not able to set budget limit.

My problem is that I wouldn't like to pay for 1000GB of bandwidth if someone for some reason decides to download one file constantly

So could some of you, who have experience with amazon, tell what happens if my app is able to handle (say 50 req/sec 30kb/page) does that mean that in the worst case I would have to pay

req * sec * min * hours * days * page size 50 * 60 * 60 * 24 * 30 * 30kb = 3888GB
