This is how I did it, pretty straight forward:
In the GoDaddy’s DNS Management settings, in the type A record, set the ‘Points to’ to the Elastic IP address of your xx.elasticbeanstalk.com site. And that’s pretty much all I did!
I can now access my amazon site using both, http://www.mysite.com and http://mysite.com. Sweet!
