We are excited to announce the launch of domain name based health checks for Amazon Route 53. You can now create Route 53 health checks against an endpoint where the IP address is not fixed or is served by multiple IPs (e.g. EC2 or RDS instances whose underlying IP addresses may change) by specifying its domain name such as server1234.example.com. You can also use domain name based health checks with Route 53's DNS failover to help improve the availability of your entire application by automatically routing requests only to healthy endpoints.
All advanced health check features like HTTPS based health checks and string-matching health checks can now also be created using domain names instead of the endpoint's IP address. You can continue to use Amazon CloudWatch to monitor the availability of your endpoints and also configure alarms and notifications in order to be alerted when one of your endpoints becomes unreachable.
Getting started is easy. To learn more, visit the Route 53 product page for full details and pricing, or see our documentation.
