A client of mine has his website domain and hosting with. We'd like to use Amazon CloudFront as CDN, but we don't want to use S3 – we'd like to keep the site files where they are on DreamHost's servers.
I'm pretty sure this is possible, since CloudFront does allow custom origins, and I signed up for CloudFront, but I am unsure how to fill out the form (what to put for origin name, etc...) even after reading the pop-up help. We are on the bellfountain server of DreamHost.
What I've Tried
Pretty much if you just put in: http://www.yourdomain.com, cloudfront figures out the rest - and you can customize from there if you need/want to - but just doing that one entry, and creating the distribution will setup a cloudfront end-point to serve the files from your external webserver - just make sure you include the 'http://' in front of the url so it can figure out the rest.
