Which AWS service or resource can automatically divert all incoming application requests to the secondary Region?

Explanations:

An Application Load Balancer distributes incoming application traffic across multiple targets in a single Region but does not have the capability to route traffic between Regions for disaster recovery.

Amazon Route 53 is a scalable Domain Name System (DNS) web service that can manage domain names and route internet traffic. It can be configured with health checks to automatically divert traffic to the secondary Region if the primary Region becomes unavailable.

AWS Direct Connect provides a dedicated network connection from your premises to AWS but does not manage routing of incoming application requests across Regions. It’s primarily for private connectivity, not for public traffic redirection.

AWS VPN provides a secure connection from an on-premises network to AWS but does not handle public internet traffic or redirect application requests between Regions for disaster recovery purposes.
