Availability zone service and regional support
Azure availability zones are physically separate locations within each Azure region. This article shows you which regions and services support availability zones.
For more information on availability zones and regions, see What are Azure regions and availability zones?,
Azure regions with availability zone support
Azure provides the most extensive global footprint of any cloud provider and is rapidly opening new regions and availability zones. Azure has availability zones in every country in which Azure operates a datacenter region.
The following regions currently support availability zones:
|Americas||Europe||Middle East||Africa||Asia Pacific|
|Brazil South||France Central||Qatar Central||South Africa North||Australia East|
|Canada Central||Germany West Central||UAE North||Central India|
|Central US||North Europe||Japan East|
|East US||Norway East||Korea Central|
|East US 2||UK South||Southeast Asia|
|South Central US||West Europe||East Asia|
|US Gov Virginia||Sweden Central||China North 3|
|West US 2||Switzerland North|
|West US 3||Poland Central|
* To learn more about availability zones and available services support in these regions, contact your Microsoft sales or customer representative. For the upcoming regions that will support availability zones, see Azure geographies.
Azure services with availability zone support
Azure services that support availability zones, including zonal and zone-redundant offerings, are continually expanding.
Three types of Azure services support availability zones: zonal, zone-redundant, and always-available services. You can combine all three of these approaches to architecture when you design your reliability strategy.
Zonal services: A resource can be deployed to a specific, self-selected availability zone to achieve more stringent latency or performance requirements. Resiliency is self-architected by replicating applications and data to one or more zones within the region. Resources are aligned to a selected zone. For example, virtual machines, managed disks, or standard IP addresses can be aligned to a same zone, which allows for increased resiliency by having multiple instances of resources deployed to different zones.
Zone-redundant services: Resources are replicated or distributed across zones automatically. For example, zone-redundant services replicate the data across multiple zones so that a failure in one zone doesn't affect the high availability of the data.
Always-available services: Always available across all Azure geographies and are resilient to zone-wide outages and region-wide outages. For a complete list of always-available services, also called non-regional services, in Azure, see Products available by region.
For more information on older-generation virtual machines, see Previous generations of virtual machine sizes.
The following tables provide a summary of the current offering of zonal, zone-redundant, and always-available Azure services. They list Azure offerings according to the regional availability of each.
In the Product Catalog, always-available services are listed as "non-regional" services.
Azure offerings are grouped into three categories that reflect their regional availability: foundational, mainstream, and strategic services. Azure's general policy on deploying services into any given region is primarily driven by region type, service category, and customer demand. For more information, see Azure services.
- Foundational services: Available in all recommended and alternate regions when a region is generally available, or within 90 days of a new foundational service becoming generally available.
- Mainstream services: Available in all recommended regions within 90 days of a region's general availability. Mainstream services are demand-driven in alternate regions, and many are already deployed into a large subset of alternate regions.
- Strategic services: Targeted service offerings, often industry-focused or backed by customized hardware. Strategic services are demand-driven for availability across regions, and many are already deployed into a large subset of recommended regions
