Azure Region Availability Reference
AUTHORITATIVE SOURCE — Consult this file BEFORE recommending any region.
Official reference: https://azure.microsoft.com/en-us/explore/global-infrastructure/products-by-region/table
How to Use
- Check if your architecture includes any limited availability services below
- If yes → refer to the table or use the MCP tool for that service to list supported regions with sufficient quota, and only offer regions that support ALL services
- If all services are "available everywhere" → offer common regions
MCP Tools Used
| Tool | Purpose |
|---|---|
mcp_azure_mcp_quota |
Check Azure region availability and quota by setting command to quota_usage_check or quota_region_availability_list |

Azure Kubernetes Service (AKS)
It has limited quota in some regions, to get available regions with enough quota, use mcp_azure_mcp_quota tool.
Azure Database for PostgreSQL
It has limited quota in some regions, to get available regions with enough quota, use mcp_azure_mcp_quota tool.
Azure OpenAI
⚠️ Very limited — varies by model

Common Architecture Patterns
| Pattern | Recommended Regions |
|---|---|
| SWA only | westus2, centralus, eastus2, westeurope, eastasia |
| SWA + backend services | westus2, centralus, eastus2, westeurope, eastasia |
| Container Apps (no SWA) | eastus, eastus2, westus2, centralus, westeurope |
| With Azure OpenAI (GPT-4o/4/3.5 + embeddings) | eastus, eastus2, swedencentral |
| SWA + Azure OpenAI (GPT-4o/4/3.5 + embeddings) | eastus2 (only region with full SWA + model overlap) |
