 In Microsoft Azure, [Availability Zones (AZ)](../availability-zones/az-overview.md) are unique physical locations within an Azure region. Each zone is made up of one or more data centers that are equipped with independent power, cooling, and networking. Availability zones protect your applications and data from data center failures.
 
-When a service in Azure Spring Cloud has availability zone enabled, Azure automatically spreads the application's deployment instance across all three zones in the selected region. If the application's deployment instance count is larger than three and is divisible by three, the instances will be spread evenly. Otherwise, the extra instance counts are spread across the remaining zones.
+When an Azure Spring Cloud service instance is created with availability zone enabled, Azure Spring Cloud will automatically distribute fundamental resources across logical sections of underlying Azure infrastructure. This distribution provides a higher level of availability to protect against a hardware failure or a planned maintenance event.
