+### Use Availability zones for better resiliency and availability
+
+Availability Zones (AZ) in Azure help protect your applications and data from datacenter failures. Each AZ is made up of one or more datacenters equipped with independent power, cooling, and networking. By designing solutions to use zonal VMs, you can isolate your VMs from failure in any other zone.
