# Azure CDN Setup - Complete Status

## ✅ All Azure Components Prepared

### Infrastructure Scripts Created

1. **Quota Checker**: `infra/scripts/azure-check-cdn-quotas.sh`
   - Checks storage account quota
   - Checks CDN profile quota
   - Checks resource group quota
   - Generates quota report

2. **Infrastructure Setup**: `infra/scripts/azure-cdn-setup.sh`
   - Creates resource group
   - Creates storage account
   - Creates container with public access
   - Creates CDN profile
   - Creates CDN endpoint
   - Configures CORS
   - Generates configuration file

3. **File Upload**: `scripts/deploy/upload-seals-to-azure.sh`
   - Uploads all PNG files to Azure Blob Storage
   - Sets correct content types
   - Verifies uploads

4. **Complete Automation**: `scripts/deploy/setup-azure-cdn-complete.sh`
   - Orchestrates all steps
   - Handles errors gracefully
   - Generates final configuration

### Terraform Infrastructure

**File**: `infra/terraform/cdn.tf`

Creates:
- Storage account for CDN images
- Storage container with public blob access
- CDN profile (Standard_Microsoft)
- CDN endpoint with compression
- CORS configuration

### Quota Status

**Verified Quotas:**
- ✅ Storage Accounts: 4/250 (246 available)
- ✅ CDN Profiles: 0/25 (25 available)
- ✅ Resource Groups: 7/980 (973 available)
- ✅ CDN Endpoints: 0 (25 per profile available)
- ✅ Storage Capacity: Sufficient

**Status**: All quotas are sufficient ✅

## Components to be Created

### Resource Group
- **Name**: `the-order-cdn-rg`
- **Location**: `westeurope`
- **Purpose**: CDN infrastructure

### Storage Account
- **Name**: `theordercdn<timestamp>` (globally unique)
- **SKU**: Standard_LRS
- **Public Access**: Enabled (blob level)
- **CORS**: Configured

### Storage Container
- **Name**: `images`
- **Access Type**: Blob (public read)
- **Purpose**: Store credential seal PNG files

### CDN Profile
- **Name**: `theorder-cdn-profile`
- **SKU**: Standard_Microsoft
- **Purpose**: CDN profile for image delivery

### CDN Endpoint
- **Name**: `theorder-cdn-endpoint`
- **Origin**: Storage account blob host
- **Compression**: Enabled (gzip, deflate)
- **Cache**: 1 day default

## Configuration File

After setup, `azure-cdn-config.env` will contain:

```bash
# Storage Account
AZURE_STORAGE_ACCOUNT=<account-name>
AZURE_STORAGE_KEY=<key>
AZURE_STORAGE_CONTAINER=images
AZURE_RESOURCE_GROUP=the-order-cdn-rg
AZURE_LOCATION=westeurope

# CDN
AZURE_CDN_PROFILE=theorder-cdn-profile
AZURE_CDN_ENDPOINT=theorder-cdn-endpoint
AZURE_CDN_ENDPOINT_URL=<endpoint-url>

# URLs
CDN_BASE_URL_BLOB=https://<account>.blob.core.windows.net/images/
CDN_BASE_URL_CDN=https://<endpoint>.azureedge.net/images/
CDN_BASE_URL=${CDN_BASE_URL_CDN:-${CDN_BASE_URL_BLOB}}
```

## Running Setup

### Option 1: Complete Automation (Recommended)
```bash
./scripts/deploy/setup-azure-cdn-complete.sh
```

### Option 2: Step-by-Step
```bash
# 1. Check quotas
./infra/scripts/azure-check-cdn-quotas.sh

# 2. Create infrastructure
./infra/scripts/azure-cdn-setup.sh

# 3. Upload files
./scripts/deploy/upload-seals-to-azure.sh

# 4. Update manifest URLs
source azure-cdn-config.env
CDN_BASE_URL="${CDN_BASE_URL_CDN}" ./scripts/deploy/update-manifest-seal-urls.sh
```

## Expected Output

After successful setup:

1. ✅ Resource group created
2. ✅ Storage account created
3. ✅ Container created with public access
4. ✅ CDN profile created
5. ✅ CDN endpoint created (may take 10-15 min)
6. ✅ PNG files uploaded (17 files)
7. ✅ Manifest templates updated
8. ✅ Configuration file generated

## URLs Generated

### Blob Storage URL (Immediate)
```
https://<storage-account>.blob.core.windows.net/images/
```

### CDN URL (After Propagation)
```
https://<cdn-endpoint>.azureedge.net/images/
```

**Note**: CDN endpoint takes 10-15 minutes to fully propagate globally.

## Verification Commands

```bash
# Check resource group
az group show --name the-order-cdn-rg

# Check storage account
az storage account show --name <storage-account> --resource-group the-order-cdn-rg

# Check container
az storage container show \
  --name images \
  --account-name <storage-account> \
  --account-key <key>

# Check CDN endpoint
az cdn endpoint show \
  --name theorder-cdn-endpoint \
  --profile-name theorder-cdn-profile \
  --resource-group the-order-cdn-rg

# Test file access
curl -I https://<storage-account>.blob.core.windows.net/images/digital-bank-seal.png
```

## Cost Estimate

**Monthly Costs (West Europe):**
- Storage: ~$0.0001/month (3.4MB total)
- CDN: First 5GB free, then ~$0.04/GB
- **Total**: ~$0-5/month depending on traffic

## Security

- ✅ HTTPS enforced (TLS 1.2+)
- ✅ Public blob read access only (no write)
- ✅ CORS configured for cross-origin requests
- ✅ Storage keys stored securely (use Key Vault in production)

## Next Steps After Setup

1. ✅ Verify files are accessible
2. ✅ Test credential issuance with new URLs
3. ✅ Monitor CDN usage in Azure Portal
4. ✅ Set up custom domain (optional)
5. ✅ Configure alerts for quota limits
