Amazon VPC Lattice resource configurations now support private domain-name targets

VPC Lattice resource configurations now support domain-name targets that are private to your network. You can define a resource configuration for a private FQDN and share it with other accounts, enabling secure cross-account access to privately-hosted resources.

Previously, only publicly resolvable domain-name targets could be shared using resource configurations. Customers with private DNS servers could not share FQDNs with other accounts using this mechanism. To enable this feature, set the'Resource Config DNS Resolution' property to 'IN_VPC' on your resource gateway. VPC Lattice uses your VPC's DNS configuration to resolveFQDNs, routing traffic to the correct backend without requiring public DNS entries.

You can enable this feature through the AWS Management Console, AWS CLI, AWS SDKs, and AWS APIs. The feature is available at no additional cost in all AWS Regions where VPC Lattice is available. For more information, see the VPC Lattice user guide.
