Is there anyway to place data transfer limits on Amazon S3 so I don't get charged beyond a certain amount?

Question

I'm try to host videos on S3 and to put data transfer limits so I don't get charged for more than say 20GB, any way to do that?

Answer 1

Not that I know of

But you could try issuing Query String Authentication Urls to S3 resources with expiration dates set. And then use the Server Access Logs to track total downloads. It you miss by a GB or so it's not going to cost too much :-)
