Amazon Web Services (AWS) has taken the wraps off DNS Failover, a new offering designed to help its Route 53 Domain Name System customers cope better with unscheduled website downtime.
DNS Failover, the company claims, can help Route 53 detect an outage on a customer’s website and redirect their end users to alternate locations where the application is operating properly.
“When you enable this feature, Route 53 health-checking agents will monitor each location (or ‘endpoint’) of your application to determine its availability,” AWS said.
“In the event an endpoint fails, Route 53 will route traffic away from the failed endpoint and to other, healthy endpoints. This helps add redundancy to your applications and maintain high availability for your end users,” the company added.
AWS is running an introductory offer of health checks for up to 50 AWS endpoints free until 31 July 2013. Subsequently, it will be charged at $0.50 (£0.32) per health check per month for endpoints within AWS and $0.75 (£0.48) per health check per month.
Full details are available on the Route 53 product page.
