Highly available and scalable cloud Domain Name System (DNS) web service.
Choose a domain name and then register it with Route 53 (domain registration).
Can do health checks on AWS resources.
Route 53 Routing Policies: - Simple Routing Policy - No health checks; simple DNS routing. - Weighted Routing Policy - Distribute traffic unequally or equally across multiple instances (kind of like load balancing but you define the balance). - Latency Routing Policy - Routes user to the closest server/instances for least latency. - Failover Routing Policy - Health checks the primary instance and if it is unhealthy, it routes user to the "failover" instance.
