Cloudfront is a caching / CDN type product made by amazon. We have it setup to use the master mirrors (dl.fedoraproject.org) as it's origin and cache access to that content. Currently we are only using it for Fedora instances in aws (mirrormanager gives them that for mirrors, which means they get a close/fast/cache of content. However, it's available from outside amazon too, so it should work to fetch other content without putting undue load on the master mirrors. The jumble of hostname there is how they make the distributions so they are unique. We could make a cname of it for more ease. Hopefully that makes sense. I am not sure we have a good story for your usecase, but at least that gives you some options... kevin
