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.

Learn moreFrequently asked questions
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.
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.
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.
