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).
