Amazon Route 53 is a highly available and scalable Domain Name System (DNS) web service. It translates human readable names, like "www.example.com", into numeric IP addresses, like 192.0.2.1.
As a DNS service, Route 53 allows you to map domain names to IP addresses or other names. Meaning end users can connect to your application using these configured domain names. Route 53 provides health checks for resources to ensure availability. It sends automated requests over the internet to a resource, such as a web server, to verify that it's reachable, available, and functional. You can also choose to receive notifications when a resource becomes unavailable and choose to route Internet traffic away from unhealthy resources.
