 ## Availability zone support
 
-Azure availability zones are at least three physically separate groups of datacenters within each Azure region. Datacenters within each zone are equipped with independent power, cooling, and networking infrastructure. In the case of a local zone failure, availability zones allow the services to failover to the other availability zones to provide continuity in service with minimal interruption. Failures can range from software and hardware failures to events such as earthquakes, floods, and fires. Tolerance to failures is achieved with redundancy and logical isolation of Azure services. For more detailed information on availability zones in Azure, see [Regions and availability zones](/azure/availability-zones/az-overview.md).

 Azure availability zones-enabled services are designed to provide the right level of resiliency and flexibility. They can be configured in two ways. They can be either zone redundant, with automatic replication across zones, or zonal, with instances pinned to a specific zone. You can also combine these approaches. For more information on zonal vs. zone-redundant architecture, see [Build solutions with availability zones](/azure/architecture/high-availability/building-solutions-for-high-availability).
