Explanation
High availability within AWS is achieved by distributing resources across multiple Availability Zones in the same Region. By updating the Auto Scaling group to span at least two Availability Zones, the application can continue serving traffic even if one zone becomes unavailable. This configuration works seamlessly with the Application Load Balancer, which automatically routes traffic only to healthy instances across those zones.
