Amazon Route 53 Now Supports Overlapping Namespaces For Private Hosted Zones
Beginning today, you can associate private hosted zones with the same Virtual Private Cloud even if they have overlapping namespaces (for example, if one of those hosted zones is a subdomain of the other, such as acme.example.com and example.com). Support for overlapping namespaces makes it easy to manage permissions across your organization. For example, it lets a central team in your organization manage a parent hosted zone (such as example.com) while allowing independent teams to manage their own subdomains of that zone (such as acme.example.com and zenith.example.com).
