7## How to Use
8 
91. Check if your architecture includes any **limited availability** services below
102. 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
113. If all services are "available everywhere" → offer common regions
12 
13## MCP Tools Used
14 
15| Tool | Purpose |
16|------|---------|
17| `mcp_azure_mcp_quota` | Check Azure region availability and quota by setting `command` to `quota_usage_check` or `quota_region_availability_list` |

21## Services with LIMITED Region Availability
22 
23### Azure Static Web Apps (SWA)
24 
25⚠️ **NOT available in many common regions**
26 
27| ✅ Available | ❌ NOT Available (will FAIL) |
28|-------------|------------------------------|
29| `westus2` | `eastus` |
30| `centralus` | `northeurope` |
31| `eastus2` | `southeastasia` |
32| `westeurope` | `uksouth` |
33| `eastasia` | `canadacentral` |
34| | `australiaeast` |
35| | `westus3` |
36

38 
39### Azure Kubernetes Service (AKS)
40 
41It has limited quota in some regions, to get available regions with enough quota, use `mcp_azure_mcp_quota` tool.
42 
43---
44 
45### Azure Database for PostgreSQL
46 
47It has limited quota in some regions, to get available regions with enough quota, use `mcp_azure_mcp_quota` tool.

51### Azure OpenAI
52 
53⚠️ **Very limited — varies by model**
54 
55| Region | GPT-4o | GPT-4 | GPT-3.5 | Embeddings |
56|--------|:------:|:-----:|:-------:|:----------:|
57| `eastus` | ✅ | ✅ | ✅ | ✅ |
58| `eastus2` | ✅ | ✅ | ✅ | ✅ |
59| `westus` | ⚠️ | ⚠️ | ✅ | ✅ |
60| `westus3` | ✅ | ⚠️ | ✅ | ✅ |
61| `southcentralus` | ✅ | ✅ | ✅ | ✅ |
62| `swedencentral` | ✅ | ✅ | ✅ | ✅ |
63| `westeurope` | ⚠️ | ✅ | ✅ | ✅ |

86## Common Architecture Patterns
87 
88| Pattern | Recommended Regions |
89|---------|---------------------|
90| SWA only | `westus2`, `centralus`, `eastus2`, `westeurope`, `eastasia` |
91| SWA + backend services | `westus2`, `centralus`, `eastus2`, `westeurope`, `eastasia` |
92| Container Apps (no SWA) | `eastus`, `eastus2`, `westus2`, `centralus`, `westeurope` |
93| With Azure OpenAI (GPT-4o/4/3.5 + embeddings) | `eastus`, `eastus2`, `swedencentral` |
94| SWA + Azure OpenAI (GPT-4o/4/3.5 + embeddings) | `eastus2` (only region with full SWA + model overlap) |
