+# AI Foundry Independent Authorization with APIM and App Roles
+
+This guide provides a deployable reference architecture in Azure that enforces independent model authorization for Azure AI Foundry by combining:
+
+- Microsoft Entra application registrations
+- Application roles
+- Azure API Management
+- APIM JWT validation and route-level authorization policies
+
+## What This Deploys
+
+- Azure AI Foundry account and default project.
+- Log Analytics and Application Insights for observability.
+- API Management gateway for model routes.
+- One API application registration with app roles derived from route rules.
+- Client application registrations and role assignments.
+- APIM per-operation JWT validation and model route enforcement.
+- Optional private networking for Foundry model endpoints:
+  - A dedicated virtual network and subnet for private endpoints.
+  - Private DNS zones and VNet links for Cognitive Services, AI Services, and OpenAI private links.
+  - AI Foundry private endpoint path via the module's private networking support.
+
+## Architecture Files
+
+- [terraform/main.tf](terraform/main.tf)
+- [terraform/providers.tf](terraform/providers.tf)
+- [terraform/variables.tf](terraform/variables.tf)
+- [terraform/outputs.tf](terraform/outputs.tf)
+- [terraform/terraform.tfvars.example](terraform/terraform.tfvars.example)
+- [scripts/deploy.sh](scripts/deploy.sh)
+- [assets/architecture.mmd](assets/architecture.mmd)
+
+## Prerequisites
+
+1. Azure subscription with permissions for resource creation and role assignments.
+1. Microsoft Entra permissions to create application registrations, service principals, and app role assignments.
+1. Terraform `>= 1.13`.
+1. Azure CLI authenticated to the target subscription.
+
+## Configuration
+
+### Core Variables
+
+- `apim_publisher_email`: Required APIM publisher email.
+- `model_authorization_rules`: Route-to-model and required role mappings.
+- `client_applications`: Client app registrations and assigned roles.
+
+### Optional Private Networking Variables
+
+Use these variables in [terraform/terraform.tfvars](terraform/terraform.tfvars) to enable private networking for Foundry model endpoints.
+
+| Variable | Type | Default | Description |
+|---|---|---|---|
+| `should_enable_foundry_private_networking` | `bool` | `false` | Enables/disables the optional VNet and private endpoint path for Foundry model traffic. |
+| `private_network_address_space` | `list(string)` | `["172.16.0.0/16"]` | Address space for the optional virtual network created by this guide. |
+| `private_endpoint_subnet_address_prefixes` | `list(string)` | `["172.16.0.0/24"]` | Address prefixes for the subnet that hosts Foundry private endpoints. |
+
+When `should_enable_foundry_private_networking = false`, the guide creates the infrastructure with public networking.
+
+When `should_enable_foundry_private_networking = true`, Terraform creates networking resources and passes the generated subnet ID to the Foundry module, which disables public access and configures private endpoint access for Foundry model endpoints.
+
+## Deployment Steps
+
+1. Open [terraform](terraform).
+1. Copy `terraform.tfvars.example` to `terraform.tfvars`.
+1. Set `apim_publisher_email` and update `model_authorization_rules` and `client_applications` as needed.
+1. Optional: set `should_enable_foundry_private_networking = true` and adjust CIDR ranges if needed.
+1. Run:
+
+```bash
+terraform init
+terraform validate
+terraform plan
+terraform apply
+```
+
+Or run the helper script:
+
+```bash
+./scripts/deploy.sh
+```
+
+## Testing Process
+
+Run tests from the Terraform directory:
+
+```bash
+cd terraform
+terraform test
+```
+
+Run a single test file:
+
+```bash
+terraform test -filter=tests/acceptance.tftest.hcl
+terraform test -filter=tests/integration.tftest.hcl
+```
+
+Validate the private networking toggle behavior:
+
+- Disabled mode (`should_enable_foundry_private_networking = false`): tests are active and assert no private networking resources are planned.
+- Enabled mode (`should_enable_foundry_private_networking = true`): plan-mode tests are currently commented out due to external module behavior.
+- Disabled-mode tests also assert the `ai_foundry_endpoint` output declaration remains present to catch core output regressions.
+
+### Known Test Limitation
+
+Enabled-mode plan tests are commented out in [terraform/tests/acceptance.tftest.hcl](terraform/tests/acceptance.tftest.hcl) and [terraform/tests/integration.tftest.hcl](terraform/tests/integration.tftest.hcl).
+
+Reason:
+
+- In [modules/ai_foundry/private_networking.tf](../../modules/ai_foundry/private_networking.tf), private DNS `data` resources use `count = var.foundry_subnet_id != null ? 1 : 0`.
+- In this guide, `foundry_subnet_id` is derived from a subnet created in the same plan, so the value is unknown at plan time for enabled mode.
+- Terraform fails with `Invalid count argument` before enabled-mode assertions can run.
+
+Current test behavior:
+
+- `terraform test` passes for active disabled-mode runs.
+- Enabled-mode runs remain documented but commented out until the external module is refactored for plan-time determinism.
+
+## Authorization Flow
+
+1. A client app requests a token for `api://<api_application_client_id>`.
+1. The client calls an APIM route such as `/gpt4o-mini/chat/completions`.
+1. APIM validates JWT issuer, audience, and role claim.
+1. APIM rewrites the route to the mapped Foundry deployment endpoint.
+1. APIM authenticates to Foundry using its managed identity.
+
+## Private Networking Notes
+
+- This guide applies private networking only to Foundry model endpoints.
+- API Management is still the ingress gateway for model routes.
+- Ensure APIM can reach the Foundry private endpoint path in your environment when private networking is enabled.
+- If deploying to an existing resource group, verify the resource group location and naming compatibility with your networking standards.
+
+## Token Request Example
+
+```bash
+TENANT_ID="<tenant-id>"
+CLIENT_ID="<client-app-client-id>"
+CLIENT_SECRET="<client-app-secret>"
+AUDIENCE="api://<api-application-client-id>"
+
+curl -s -X POST "https://login.microsoftonline.com/${TENANT_ID}/oauth2/v2.0/token" \
+  -H "Content-Type: application/x-www-form-urlencoded" \
+  -d "client_id=${CLIENT_ID}" \
+  -d "client_secret=${CLIENT_SECRET}" \
+  -d "scope=${AUDIENCE}/.default" \
+  -d "grant_type=client_credentials"
+```
+
+## APIM Call Example
+
+```bash
+APIM_MODELS_BASE_URL="https://<apim-name>.azure-api.net/models"
+ACCESS_TOKEN="<token>"
+
+curl -s -X POST "${APIM_MODELS_BASE_URL}/gpt4o-mini/chat/completions" \
+  -H "Authorization: Bearer ${ACCESS_TOKEN}" \
+  -H "Content-Type: application/json" \
+  -d '{"messages":[{"role":"user","content":"Hello"}]}'
+```
+
+## Notes on AVM Usage
+
+This guide uses the following modules:
+
+- `Azure/avm-res-insights-component/azurerm`
+- `Azure/naming/azurerm`
+- `modules/ai_foundry`
+- `modules/ai_foundry_project`
+- `modules/common_models`
+
+Azure Verified Modules catalog reference:
+
+- <https://azure.github.io/Azure-Verified-Modules/indexes/terraform/tf-resource-modules/>
+
+## Cleanup
+
+```bash
+terraform destroy
+```
