Question

A company runs identical copies of a stateless web application in the us-east-1 and ap-southeast-1 Regions, each behind its own Application Load Balancer. Users are distributed globally, and the company wants each user to be automatically directed to the Region that provides the lowest network latency for them, while still ensuring traffic is never sent to a Region whose application is unhealthy. Which Route 53 configuration meets these requirements?

Accepted Answer

Create latency-based routing records for each ALB and associate a Route 53 health check with each record.

Answer

Create geolocation routing records that map continents to the nearest Region, without health checks.

Answer

Create weighted routing records with equal weights for both ALBs and associate health checks with each.

Answer

Create a single failover routing record set with us-east-1 as primary and ap-southeast-1 as secondary.
