dns - Amazon S3: Static Web Sites: Custom Domain or Subdomain

Question

Amazon.com just announced that one can host static web sites in a S3 bucket. I went to their setup page at http://docs.amazonwebservices.com/AmazonS3/latest/dev/index.html?WebsiteHosting.html and created a bucket for my static web site, and it worked fine. I have an URL of the form http://[my bucket name].s3-website-us-east-1.amazonaws.com/.

However, I would like to point a subdomain that I own (e.g. static.mydomain.com) to my static web site at Amazon S3. Has anybody figured out how to do that?

I appreciate any help you can give me.

Answer 1

It turns out that to make it work, you cannot just map any arbitrary subdomain to any arbitrary bucket. The fully qualified subdomain name must be the same as the S3 bucket name.

1. Suppose the name of your site is static.mydomain.com. Then you need to create a S3 bucket with that same name, named static.mydomain.com.
2. Once you configure that bucket as a S3 static web site, it will have a URL assigned to it that looks something like http://static.mydomain.com.s3-website-us-east-1.amazonaws.com.
3. Go to your domain host and map your subdomain to the URL from step 2. In enom.com, that meant mapping the host "static" to the address "static.mydomain.com.s3-website-us-east-1.amazonaws.com" as a CNAME record.

Thanks to Uriah and David for suggestions. I eventually got my answer at an Amazon AWS forum.
