Azure Availability Zones

Availability Zones are physically separate datacenter locations within an Azure region. They provide independent power, cooling, and networking so you can design high availability workloads with minimal latency.

Azure regions with Availability Zone support

Deploy your resources across zones within a region to achieve higher resiliency without significantly increasing latency.

Frequently asked questions

How can I verify service support for a region?
Microsoft publishes service availability for each region. Visit the Azure products by region page to confirm support for your workloads.
Do Availability Zones add latency?
Availability Zones are designed to maintain low-latency connections within a region. Azure keeps zones physically separate yet close enough to support synchronous replication.
What resiliency options use zones?
Many Azure services support zonal or zone-redundant deployments. Review service-specific documentation to understand how zones improve availability and recovery objectives.
