To provide the most high-performing experience for the users of the application, a solutions architect should use a latency routing policy for the Route 53 A record. This policy allows Route 53 to route traffic to the AWS Region that provides the lowest possible latency for the users1. A latency routing policy can also improve the availability of the application, as Route 53 can automatically route traffic to another Region if the primary Region becomes unavailable2.
