Amazon Route 53 is a highly available and scalable cloud Domain Name System (DNS) web service. It is designed to give developers and businesses an extremely reliable and cost-effective way to route end users to Internet applications by translating names into the numeric IP addresses like 192.0.2.1 that computers use to connect to each other. Amazon Route 53 is fully compliant with IPv6 as well. Amazon Route 53 effectively connects user requests to infrastructure running in AWS, such as Amazon EC2 instances, Elastic Load Balancing load balancers, or Amazon S3 buckets, and can also be used to route users to infrastructure outside of AWS. You can use Amazon Route 53 to configure DNS health checks, then continuously monitor your applications’ ability to recover from failures and control application recovery with Route 53 Application Recovery Controller. Amazon Route 53 Traffic Flow makes it easy for you to manage traffic globally through a variety of routing types.
