## AI overview

This how-to article explains availability-zone redundancy for Azure Application Gateway. It describes the redundancy model, the shared responsibility boundary, and how to verify whether a gateway is zone-redundant or zonal using Azure CLI and Resource Graph. It also cautions that a redundant gateway does not by itself make the services behind it redundant.
