Q

Achieving High Availability through Multiple Availability Zones

A

High availability is achieved by deploying resources across multiple Availability Zones. If one Availability Zone experiences an issue, the workload can be automatically routed to another AZ without service interruption.
Availability Zones do not share single points of failure, ensuring that failures are isolated to specific zones and not affecting other AZs.
