Azure has announced the public preview of Azure Availability Zones mid of last month. The feature is currently available in two regions which are US East and West Europe.

Availability Zones help to protect you from datacenter-level failures. They are located inside an Azure region, and each one has its own independent power source, network, and cooling. To ensure resiliency, there’s a minimum of three separate zones in all enabled regions. The physical and logical separation of Availability Zones within a region protects applications and data from zone-level failures.

Below services are currently supported on Availability Zones. and the supported VM size families are Av2, Dv2 and DSv2

• Linux Virtual Machines
• Windows Virtual Machines
• Zonal Virtual Machine Scale Sets
• Managed Disks
• Load Balancer
