Question

A company runs an identical stateless web application in two AWS Regions: us-east-1 and ap-southeast-1. Both deployments sit behind Application Load Balancers and are fully active. Users are globally distributed, and the operations team is receiving complaints that some users in Asia experience slow response times even though the ap-southeast-1 stack is healthy and underutilized. The team wants to ensure each user is automatically directed to the Region that gives them the best response time while retaining automatic failover if a Region becomes unhealthy. Which Route 53 configuration should the team implement?

Accepted Answer

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

Answer

Create a weighted routing policy assigning equal weights to both ALBs with health checks attached to each record.

Answer

Create a geolocation routing policy mapping continents to the nearest Region with a default record pointing to us-east-1.

Answer

Create a simple routing record with both ALB IP addresses so Route 53 returns all values in random order.
