Azure AI Search regions list
This article identifies the cloud regions in which Azure AI Search is available. It also lists which premium features are available in each region.
Features subject to regional availability
| Feature | Availability |
|---|---|
| Extra capacity | Higher capacity partitions became available in selected regions starting in April 2024 with a second wave following in May 2024. If you're using an older search service, create a new search service to benefit from more capacity at the same billing rate. To check existing capacity, find your search service and select the Properties tab in the middle of the Overview page. To check search service age, follow these instructions. Currently, there are just a few regions that don't offer higher capacity partitions. Regional support for extra capacity is noted in the footnotes of this article. |
| Availability zones | Divides a region's data centers into distinct physical location groups, providing high-availability within the same geo. Regional support is noted in this article. |
| Azure AI enrichment | Refers to skills that make internal calls to Azure AI for enrichment and transformation during indexing. Integration requires that Azure AI Search coexists with an Azure AI multi-service account in the same physical region. Regional support is noted in this article. |
| Azure OpenAI integration | Refers to skills and vectorizers that make internal calls to deployed embedding and chat models on Azure OpenAI. Check Azure OpenAI model region availability for the most current list of regions for each embedding and chat model. Specific Azure OpenAI models are in fewer regions, so be sure to check for joint regional availability before installing. |
| Azure AI Studio integration | Refers to skills and vectorizers that make internal calls to the models hosted in the model catalog. Check Azure AI Studio region availability for the most current list of regions. |
