A company is migrating a critical application to AWS and needs to ensure high availability across AWS Regions. The application uses a relational database. Which THREE components are necessary for this multi-region architecture?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Application Load Balancer in each region
For a multi-region architecture ensuring high availability, three key components are required: an Application Load Balancer in each region to distribute traffic locally, Amazon Route 53 with failover routing policy to direct traffic to the healthy region, and an Amazon RDS cross-Region read replica to provide database disaster recovery and read scalability. Option A (RDS Multi-AZ) is incorrect because it only provides high availability within a single region, not across regions. Option E (VPC peering) is incorrect because VPC peering does not provide high availability; it is a networking feature for connecting VPCs, typically within the same region or across regions for private communication, but it is not a component for multi-region HA architecture.
