Zone Apex / Naked Domain / Root Domain CNAME Support for Amazon EC2, Google App Engine and Other Cloud Hosts

What this post added

This post introduces CNAME Flattening, a feature that overcomes DNS RFC limitations to allow zone apex domains (naked domains) to be CNAME records. This directly benefits users of cloud hosting providers like AWS EC2, Google App Engine, and Rackspace, enabling them to point their root domains to these services without requiring workarounds, thereby improving flexibility and performance.
