Explanation

Deploying the application across multiple Availability Zones in an AWS Region ensures high availability and fault tolerance. Availability Zones are physically separated data centers within a region that are designed to be isolated from failures in other zones. By distributing your application across multiple zones, you can ensure that if one zone experiences an issue, the other zones will continue to operate, minimizing downtime and improving reliability.
