Easy way to filter traffic from Cloud Services (AWS/Azure etc)

[#1]

We have a significant volume of automated traffic hitting our site from AWS instances (likely crawlers). We've looked in the raw logs for something to identify this traffic, but there it comes from a wide range of IP addresses, sometimes showing the ISP domain as amazonaws.com, mostly from their Virginia data centre and doesn't give a helpful user agent.

To filter this out we'd need to create a complex IP filter rule and update it each time AWS acquire new IP addresses. Given that this is a common rule that many clients will require, and given the rapid growth of cloud compute services, it would make sense for Adobe to offer and maintain a bot rule to exclude AWS/Azure/rackspace etc.
