Another way is to use DNS hosting service, for example, Amazon Route 53.
Details can be found here: http://support.rightscale.com/03-Tutorials/02-AWS/02-Website_Edition/2._Deployment_Setup/4._Domain_Setup/Domain_Setup_with_Amazon's_Route_53
The whole point is:
YourDomainRegistrar =====> DnsHostingService ======> ElasticIpOfYourEC2

ns1.dnsservice.com A Records
ns2.dnsservice.com

If you have your domain "mydomain.com" registered with GoDaddy.com, you can go to the GoDaddy DNS Manager, select Edit Zone for your domain, and put the your AWS EC2 instance's Elastic IP, for example, 123.123.123.123, in the box provided for the A record.
A(Host) | Points to
----------+------------------
@ | 123.123.123.123
Here, @ stands for 'this', i.e. mydomain.com. This A record will resolve the following:
mydomain.com --> 123.123.123.123
Obviously, it does not resolve the subdomain www.mydomain.com. You have to add CNAME record:
CNAME(Alias) | Points to
---------------+------------------
www | @
This CNAME record will resolve the following
www.mydomain.com --> @ (mydomain.com) --> 123.123.123.123
As with most DNS changes, you may need to wait up until 24 hours for your change being propagated. GoDaddy takes less than 2 hours to push the change.
