Amazon S3: Spending Cap

Question

Amazon Web Services

Is there any way to limit the cost of S3 per day? I’m going to use it for a couple of projects, but the post-payment scares me: StackOverflow gave frightening invoice calculations from Amazon in case someone decides to play around and put a couple of files on “eternal” download.

Answer 1

You can prohibit public access and give signed links to files - after a certain time (set by the signature), access will be impossible.
The keyword is amazon s3 signed url.
for example, the implementation of this feature for .net is discussed here forums.aws.amazon.com/message.jspa?messageID=136452

Answer 2

So far, they have only advised to keep an instance for analyzing logs (CloudFront can write a return log to the S3 bucket) and, in which case, stop distributing. But this is not quite the same, and the logging delay is about an hour.

Answer 3

Amazon has expensive traffic, do caching at your place so that you don’t have to pull the second one, etc. times the same file
