Amazon Route 53 provides three main functions:
- Domain registration
- allows you to register domain names
- Domain Name System (DNS) service
- translates friendly domains names like www.example.com into IP addresses like 192.0.2.1
- responds to DNS queries using a global network of authoritative DNS servers, which reduces latency
- can route Internet traffic to CloudFront, Elastic Beanstalk, ELB, or S3. There’s no charge for DNS queries to these resources
- Health checking
- can monitor the health of resources such as web and email servers.
- sends automated requests over the Internet to the application to
verify that it’s reachable, available, and functional - CloudWatch alarms can be configured for the health checks to send notification when a resource becomes unavailable.
- can be configured to route Internet traffic away from resources that are unavailable
