Amazon Route 53 Resolver endpoints now support DNS delegation for private hosted zones

Starting today, domain name system (DNS) delegation for private hosted zone subdomains can be used with Route 53 inbound and outbound Resolver endpoints. This allows you to delegate the authority for a subdomain from your on-premises infrastructure to the Route 53 Resolver cloud service and vice versa, enabling a simplified cloud experience across namespaces in AWS and on your own local infrastructure.

AWS customers allow multiple organizations within their enterprise to individually manage their respective subdomains and subzones, whereas apex domains and parent hosted zones are typically overseen by a central team. Previously, these customers had to create and maintain conditional forwarding rules in their existing network infrastructure to enable services to discover one another across subdomains. However, conditional forwarding rules are difficult to maintain across large organizations and, in many cases, are not supported by on-premises infrastructure. With today’s release, customers can instead delegate authority of subdomains to Route 53 using name server records and vice versa, achieving compatibility with common, on-premises DNS infrastructure and removing the need for teams to use conditional forwarding rules throughout their organization.

Inbound and outbound delegation for Resolver endpoints is available globally in all AWS Regions, where Resolver endpoints are available, except in AWS GovCloud and Amazon Web Services in China. Inbound and outbound delegation is provided at no additional cost to Resolver endpoints usage.
