We're excited to make three announcements today regarding Amazon Route 53, AWS’s highly available and scalable Domain Name System (DNS) service.
First, Amazon Route 53 has integrated with Elastic Load Balancing (ELB) in order to easily let you map your root domain, or "zone apex" (e.g. mydomain.com without the 'www') directly to your Elastic Load Balancer. We’re excited that by integrating Elastic Load Balancing and Amazon Route 53, we’re offering our customers a solution that can be implemented in minutes while maintaining the high level of reliability that customers expect from Amazon Web Services.
Second, Amazon Route 53 now offers Weighted Round Robin (WRR) functionality, allowing developers to specify the frequency (“weights”) with which different DNS responses are returned to end users. You can use WRR to bring servers into production, perform A/B testing, or balance your traffic across regions or data centers of varying sizes. Since we launched Amazon Route 53, this has been one of the most frequently requested features, so we’re happy to make this feature available today.
Lastly, Amazon Route 53 has announced General Availability along with a 100% Service Level Agreement (SLA), backing up the service’s reliability with service credits in case of downtime.
