title: AWS S3 bucket redirect vs DNS CNAME for subdomain in static website hosting
body: <p><a href="http://docs.aws.amazon.com/fr_fr/gettingstarted/latest/swh/website-hosting-intro.html" rel="nofollow">AWS S3 website hosting guide</a> recommend to setup a subdomain in a way which is not clear for me</p>
  
  <p>is there any reason why AWS recommend to setup an A record (alias) to an S3 bucket for the (www) subdomain and the subdomain then later redirect to another S3 bucket?</p>
  
  <p>would not is be better just to setup a CNAME DNS record instead of this double redirection? </p>
