Explanation

By creating an Amazon Route 53 Resolver outbound endpoint and configuring forwarding rules to send DNS queries to the on-premises DNS servers, EC2 instances in the VPC can dynamically resolve hostnames in the on-premises data center. This solution leverages AWS managed DNS forwarding and minimizes ongoing maintenance compared to manually maintaining DNS records or host file configurations.
