## 📋 Overview

This guide will help you create and configure all necessary Azure resources to deploy the CMDB Insight application. The setup includes:

### Required Resources

1. **Resource Group** - Container for all resources
2. **Azure Container Registry (ACR)** - Store Docker images
3. **Azure Database for PostgreSQL** - Production database (recommended)
4. **Azure Key Vault** - Secure storage for secrets
5. **Azure App Service Plan** - Hosting plan for web apps
6. **Azure App Service (Backend)** - Backend API service
7. **Azure App Service (Frontend)** - Frontend web application
8. **Application Insights** - Monitoring and logging
9. **DNS & SSL** - Custom domain and HTTPS certificate

### Estimated Costs

- **Basic Setup (SQLite)**: €17-35/month
- **Recommended Setup (PostgreSQL)**: €36-62/month

---

## 🚀 Prerequisites

Before starting, ensure you have:

- [ ] Azure CLI installed (`az --version`)
- [ ] Azure subscription with appropriate permissions
- [ ] Docker installed (for local testing)
- [ ] Access to Azure Portal
- [ ] Jira credentials (OAuth client ID/secret or Personal Access Token)

### Install Azure CLI (if needed)

```bash
# macOS
brew install azure-cli

# Linux
curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash

# Windows
# Download from: https://aka.ms/installazurecliwindows
```

### Login to Azure

```bash
az login
az account list --output table
az account set --subscription "<subscription-id-or-name>"
```

---

## 📦 Step 1: Create Resource Group

Create a resource group to organize all resources:

```bash
# Set variables (customize as needed)
RESOURCE_GROUP="rg-cmdb-insight-prod"
LOCATION="westeurope"  # or your preferred region

# Create resource group
az group create \
  --name $RESOURCE_GROUP \
  --location $LOCATION

# Verify
az group show --name $RESOURCE_GROUP
```

**Note**: Choose a location close to your users. Common options:
- `westeurope` (Netherlands, Germany)
- `northeurope` (Ireland, UK)
- `eastus` (US East)

---

## 🐳 Step 2: Create or Use Existing Azure Container Registry (ACR)

**Important**: Azure Container Registry can be **shared across multiple applications**. The repository name (`cmdb-insight`) is what separates this application from others in the same ACR.

### Option A: Use Existing ACR (Recommended if you have one)

If you already have an ACR for other applications, you can reuse it:

```bash
# Set variables - use your existing ACR name
ACR_NAME="your-existing-acr"  # Your existing ACR name
ACR_RESOURCE_GROUP="rg-shared-services"  # Resource group where ACR exists

# Verify ACR exists
az acr show --name $ACR_NAME --resource-group $ACR_RESOURCE_GROUP

# Get ACR login server
ACR_LOGIN_SERVER=$(az acr show --name $ACR_NAME --resource-group $ACR_RESOURCE_GROUP --query loginServer --output tsv)
echo "ACR Login Server: $ACR_LOGIN_SERVER"
```

**Benefits of reusing ACR**:
- ✅ Cost savings (one ACR for all apps)
- ✅ Centralized image management
- ✅ Easier to share images across teams
- ✅ Better resource utilization

### Option B: Create New ACR

If you don't have an ACR yet, create one:

```bash
# Set variables
ACR_NAME="yourcompanyacr"  # Must be globally unique, lowercase, 5-50 chars, alphanumeric only
ACR_RESOURCE_GROUP="rg-shared-services"  # Or use your app resource group
SKU="Standard"  # Options: Basic, Standard, Premium

# Create resource group for shared services (if needed)
az group create --name $ACR_RESOURCE_GROUP --location westeurope

# Create ACR
az acr create \
  --resource-group $ACR_RESOURCE_GROUP \
  --name $ACR_NAME \
  --sku $SKU \
  --admin-enabled true

# Get ACR login server
ACR_LOGIN_SERVER=$(az acr show --name $ACR_NAME --resource-group $ACR_RESOURCE_GROUP --query loginServer --output tsv)
echo "ACR Login Server: $ACR_LOGIN_SERVER"

# Get admin credentials (save these securely)
az acr credential show --name $ACR_NAME
```

**ACR SKU Comparison**:
- **Basic**: €5/month - Development/test, 10GB storage
- **Standard**: €20/month - Production, 100GB storage, geo-replication (recommended)
- **Premium**: €50/month - Enterprise, 500GB storage, advanced security

**Repository Structure in ACR**:
```
yourcompanyacr.azurecr.io/
├── cmdb-insight/          ← This application
│   ├── backend:latest
│   └── frontend:latest
├── other-app/             ← Other applications
│   ├── api:latest
│   └── web:latest
└── shared-services/        ← Shared images
    └── nginx:latest
```

### Test ACR Connection

```bash
# Login to ACR
az acr login --name $ACR_NAME

# Verify
az acr repository list --name $ACR_NAME

# List repositories (you'll see cmdb-insight after first push)
az acr repository list --name $ACR_NAME --output table
```

---

## 🗄️ Step 3: Create Azure Database for PostgreSQL

PostgreSQL is recommended for production. Alternatively, you can use SQLite with Azure Storage (see Step 3B).

### Step 3A: PostgreSQL (Recommended)

```bash
# Set variables
DB_SERVER_NAME="cmdb-postgres-prod"  # Must be globally unique
RESOURCE_GROUP="rg-cmdb-insight-prod"
DB_ADMIN_USER="cmdbadmin"
DB_ADMIN_PASSWORD="<generate-secure-password>"  # Use a strong password!
DB_NAME="cmdb"
SKU="Standard_B1ms"  # Burstable tier, 1 vCore, 2GB RAM

# Generate secure password (save this!)
DB_ADMIN_PASSWORD=$(openssl rand -base64 32)
echo "Database Password: $DB_ADMIN_PASSWORD"

# Create PostgreSQL Flexible Server
az postgres flexible-server create \
  --resource-group $RESOURCE_GROUP \
  --name $DB_SERVER_NAME \
  --location westeurope \
  --admin-user $DB_ADMIN_USER \
  --admin-password $DB_ADMIN_PASSWORD \
  --sku-name $SKU \
  --tier Burstable \
  --storage-size 32 \
  --version 15 \
  --public-access 0.0.0.0  # Allow Azure services (restrict later if needed)

# Create database
az postgres flexible-server db create \
  --resource-group $RESOURCE_GROUP \
  --server-name $DB_SERVER_NAME \
  --database-name $DB_NAME

# Get connection string
DB_CONNECTION_STRING="postgresql://${DB_ADMIN_USER}:${DB_ADMIN_PASSWORD}@${DB_SERVER_NAME}.postgres.database.azure.com:5432/${DB_NAME}?sslmode=require"
echo "Database Connection String: $DB_CONNECTION_STRING"

# Save connection details securely
echo "DB_HOST=${DB_SERVER_NAME}.postgres.database.azure.com" > .env.azure
echo "DB_USER=${DB_ADMIN_USER}" >> .env.azure
echo "DB_PASSWORD=${DB_ADMIN_PASSWORD}" >> .env.azure
echo "DB_NAME=${DB_NAME}" >> .env.azure
```

**PostgreSQL SKU Options**:
- **Standard_B1ms**: €20-30/month - 1 vCore, 2GB RAM (recommended for 20 users)
- **Standard_B2s**: €40-50/month - 2 vCores, 4GB RAM (for growth)
- **Standard_D2s_v3**: €100+/month - 2 vCores, 8GB RAM (high performance)

### Step 3B: SQLite with Azure Storage (Alternative)

If you prefer to use SQLite (simpler, but less scalable):

```bash
# Set variables
STORAGE_ACCOUNT_NAME="cmdbstorage$(openssl rand -hex 4)"  # Must be globally unique, lowercase
RESOURCE_GROUP="rg-cmdb-insight-prod"

# Create storage account
az storage account create \
  --resource-group $RESOURCE_GROUP \
  --name $STORAGE_ACCOUNT_NAME \
  --location westeurope \
  --sku Standard_LRS

# Get storage account key
STORAGE_KEY=$(az storage account keys list \
  --resource-group $RESOURCE_GROUP \
  --account-name $STORAGE_ACCOUNT_NAME \
  --query "[0].value" --output tsv)

echo "Storage Account: $STORAGE_ACCOUNT_NAME"
echo "Storage Key: $STORAGE_KEY"
```

**Note**: SQLite works but has limitations with concurrent users. PostgreSQL is recommended for production.

---

## 🔐 Step 4: Create Azure Key Vault

Key Vault securely stores secrets like API keys, passwords, and tokens.

```bash
# Set variables
KEY_VAULT_NAME="kv-cmdb-insight-prod"  # Must be globally unique
RESOURCE_GROUP="rg-cmdb-insight-prod"

# Create Key Vault
az keyvault create \
  --name $KEY_VAULT_NAME \
  --resource-group $RESOURCE_GROUP \
  --location westeurope \
  --sku standard

# Verify
az keyvault show --name $KEY_VAULT_NAME --resource-group $RESOURCE_GROUP
```

### Add Secrets to Key Vault

```bash
# Set your actual values
JIRA_PAT="your-jira-personal-access-token"
SESSION_SECRET=$(openssl rand -hex 32)
JIRA_OAUTH_CLIENT_ID="your-oauth-client-id"
JIRA_OAUTH_CLIENT_SECRET="your-oauth-client-secret"

# Add secrets
az keyvault secret set \
  --vault-name $KEY_VAULT_NAME \
  --name "JiraPat" \
  --value "$JIRA_PAT"

az keyvault secret set \
  --vault-name $KEY_VAULT_NAME \
  --name "SessionSecret" \
  --value "$SESSION_SECRET"

az keyvault secret set \
  --vault-name $KEY_VAULT_NAME \
  --name "JiraOAuthClientId" \
  --value "$JIRA_OAUTH_CLIENT_ID"

az keyvault secret set \
  --vault-name $KEY_VAULT_NAME \
  --name "JiraOAuthClientSecret" \
  --value "$JIRA_OAUTH_CLIENT_SECRET"

# If using PostgreSQL, add database password
az keyvault secret set \
  --vault-name $KEY_VAULT_NAME \
  --name "DatabasePassword" \
  --value "$DB_ADMIN_PASSWORD"
```

---

## 📊 Step 5: Create Application Insights

Application Insights provides monitoring, logging, and performance metrics.

```bash
# Set variables
APP_INSIGHTS_NAME="appi-cmdb-insight-prod"
RESOURCE_GROUP="rg-cmdb-insight-prod"

# Create Application Insights
az monitor app-insights component create \
  --app $APP_INSIGHTS_NAME \
  --location westeurope \
  --resource-group $RESOURCE_GROUP \
  --application-type web

# Get Instrumentation Key
INSTRUMENTATION_KEY=$(az monitor app-insights component show \
  --app $APP_INSIGHTS_NAME \
  --resource-group $RESOURCE_GROUP \
  --query instrumentationKey --output tsv)

echo "Instrumentation Key: $INSTRUMENTATION_KEY"
```

**Note**: Application Insights Basic tier is free up to 5GB/month, which is sufficient for most small applications.

---

## 🖥️ Step 6: Create App Service Plan

App Service Plan defines the compute resources for your web apps.

```bash
# Set variables
APP_SERVICE_PLAN_NAME="plan-cmdb-insight-prod"
RESOURCE_GROUP="rg-cmdb-insight-prod"
SKU="B1"  # Basic tier, 1 vCore, 1.75GB RAM

# Create App Service Plan (Linux)
az appservice plan create \
  --name $APP_SERVICE_PLAN_NAME \
  --resource-group $RESOURCE_GROUP \
  --sku $SKU \
  --is-linux

# Verify
az appservice plan show --name $APP_SERVICE_PLAN_NAME --resource-group $RESOURCE_GROUP
```

**App Service Plan SKU Options**:
- **B1**: €15-25/month - 1 vCore, 1.75GB RAM (recommended for 20 users)
- **B2**: €30-40/month - 2 vCores, 3.5GB RAM
- **S1**: €50-70/month - 1 vCore, 1.75GB RAM (Standard tier, better performance)

---

## 🚀 Step 7: Create App Services (Backend & Frontend)

Create two web apps: one for backend API and one for frontend.

### Step 7A: Create Backend App Service

```bash
# Set variables
BACKEND_APP_NAME="cmdb-backend-prod"  # Must be globally unique
RESOURCE_GROUP="rg-cmdb-insight-prod"
APP_SERVICE_PLAN_NAME="plan-cmdb-insight-prod"
ACR_NAME="cmdbinsightacr"  # From Step 2

# Create backend web app
az webapp create \
  --name $BACKEND_APP_NAME \
  --resource-group $RESOURCE_GROUP \
  --plan $APP_SERVICE_PLAN_NAME \
  --deployment-container-image-name "${ACR_NAME}.azurecr.io/cmdb-insight/backend:latest"

# Enable Managed Identity (for ACR access)
az webapp identity assign \
  --name $BACKEND_APP_NAME \
  --resource-group $RESOURCE_GROUP

# Get Managed Identity Principal ID
BACKEND_PRINCIPAL_ID=$(az webapp identity show \
  --name $BACKEND_APP_NAME \
  --resource-group $RESOURCE_GROUP \
  --query principalId --output tsv)

# Grant ACR pull permissions
ACR_ID=$(az acr show --name $ACR_NAME --resource-group $RESOURCE_GROUP --query id --output tsv)
az role assignment create \
  --assignee $BACKEND_PRINCIPAL_ID \
  --role AcrPull \
  --scope $ACR_ID

# Configure container settings
az webapp config container set \
  --name $BACKEND_APP_NAME \
  --resource-group $RESOURCE_GROUP \
  --docker-custom-image-name "${ACR_NAME}.azurecr.io/cmdb-insight/backend:latest" \
  --docker-registry-server-url "https://${ACR_NAME}.azurecr.io"

# Set environment variables
az webapp config appsettings set \
  --name $BACKEND_APP_NAME \
  --resource-group $RESOURCE_GROUP \
  --settings \
    NODE_ENV=production \
    PORT=3001 \
    DATABASE_TYPE=postgres \
    DATABASE_URL="@Microsoft.KeyVault(SecretUri=https://${KEY_VAULT_NAME}.vault.azure.net/secrets/DatabasePassword/)" \
    JIRA_HOST=https://jira.zuyderland.nl \
    JIRA_AUTH_METHOD=oauth \
    JIRA_OAUTH_CLIENT_ID="@Microsoft.KeyVault(SecretUri=https://${KEY_VAULT_NAME}.vault.azure.net/secrets/JiraOAuthClientId/)" \
    JIRA_OAUTH_CLIENT_SECRET="@Microsoft.KeyVault(SecretUri=https://${KEY_VAULT_NAME}.vault.azure.net/secrets/JiraOAuthClientSecret/)" \
    JIRA_OAUTH_CALLBACK_URL="https://${BACKEND_APP_NAME}.azurewebsites.net/api/auth/callback" \
    SESSION_SECRET="@Microsoft.KeyVault(SecretUri=https://${KEY_VAULT_NAME}.vault.azure.net/secrets/SessionSecret/)" \
    FRONTEND_URL="https://${FRONTEND_APP_NAME}.azurewebsites.net" \
    APPINSIGHTS_INSTRUMENTATIONKEY="${INSTRUMENTATION_KEY}"

# Grant Key Vault access to backend
az keyvault set-policy \
  --name $KEY_VAULT_NAME \
  --object-id $BACKEND_PRINCIPAL_ID \
  --secret-permissions get list

# Enable HTTPS only
az webapp update \
  --name $BACKEND_APP_NAME \
  --resource-group $RESOURCE_GROUP \
  --https-only true
```

### Step 7B: Create Frontend App Service

```bash
# Set variables
FRONTEND_APP_NAME="cmdb-frontend-prod"  # Must be globally unique
RESOURCE_GROUP="rg-cmdb-insight-prod"
APP_SERVICE_PLAN_NAME="plan-cmdb-insight-prod"
ACR_NAME="cmdbinsightacr"  # From Step 2

# Create frontend web app
az webapp create \
  --name $FRONTEND_APP_NAME \
  --resource-group $RESOURCE_GROUP \
  --plan $APP_SERVICE_PLAN_NAME \
  --deployment-container-image-name "${ACR_NAME}.azurecr.io/cmdb-insight/frontend:latest"

# Enable Managed Identity
az webapp identity assign \
  --name $FRONTEND_APP_NAME \
  --resource-group $RESOURCE_GROUP

# Get Managed Identity Principal ID
FRONTEND_PRINCIPAL_ID=$(az webapp identity show \
  --name $FRONTEND_APP_NAME \
  --resource-group $RESOURCE_GROUP \
  --query principalId --output tsv)

# Grant ACR pull permissions
az role assignment create \
  --assignee $FRONTEND_PRINCIPAL_ID \
  --role AcrPull \
  --scope $ACR_ID

# Configure container settings
az webapp config container set \
  --name $FRONTEND_APP_NAME \
  --resource-group $RESOURCE_GROUP \
  --docker-custom-image-name "${ACR_NAME}.azurecr.io/cmdb-insight/frontend:latest" \
  --docker-registry-server-url "https://${ACR_NAME}.azurecr.io"

# Set environment variables
az webapp config appsettings set \
  --name $FRONTEND_APP_NAME \
  --resource-group $RESOURCE_GROUP \
  --settings \
    VITE_API_URL="https://${BACKEND_APP_NAME}.azurewebsites.net/api"

# Enable HTTPS only
az webapp update \
  --name $FRONTEND_APP_NAME \
  --resource-group $RESOURCE_GROUP \
  --https-only true
```

---

## 🔄 Step 8: Build and Push Docker Images

Before the apps can run, you need to build and push Docker images to ACR.

### Option A: Using Script (Recommended)

```bash
# Navigate to project root
cd /path/to/cmdb-insight

# Set environment variables
export ACR_NAME="cmdbinsightacr"  # Your ACR name
export REPO_NAME="cmdb-insight"

# Build and push
./scripts/build-and-push-azure.sh
```

### Option B: Manual Build and Push

```bash
# Set variables
ACR_NAME="cmdbinsightacr"
REGISTRY="${ACR_NAME}.azurecr.io"
REPO_NAME="cmdb-insight"

# Login to ACR
az acr login --name $ACR_NAME

# Build backend
docker build -t ${REGISTRY}/${REPO_NAME}/backend:latest \
  -f backend/Dockerfile.prod ./backend

# Build frontend
docker build -t ${REGISTRY}/${REPO_NAME}/frontend:latest \
  -f frontend/Dockerfile.prod ./frontend

# Push images
docker push ${REGISTRY}/${REPO_NAME}/backend:latest
docker push ${REGISTRY}/${REPO_NAME}/frontend:latest

# Verify
az acr repository list --name $ACR_NAME
az acr repository show-tags --name $ACR_NAME --repository ${REPO_NAME}/backend
az acr repository show-tags --name $ACR_NAME --repository ${REPO_NAME}/frontend
```

---

## 🌐 Step 9: Configure Custom Domain and SSL (Optional)

If you have a custom domain (e.g., `cmdb.yourcompany.com`):

### Step 9A: Add Custom Domain

```bash
# Set variables
FRONTEND_APP_NAME="cmdb-frontend-prod"
BACKEND_APP_NAME="cmdb-backend-prod"
CUSTOM_DOMAIN="cmdb.yourcompany.com"
RESOURCE_GROUP="rg-cmdb-insight-prod"

# Add custom domain to frontend
az webapp config hostname add \
  --webapp-name $FRONTEND_APP_NAME \
  --resource-group $RESOURCE_GROUP \
  --hostname $CUSTOM_DOMAIN

# Add custom domain to backend (if needed)
az webapp config hostname add \
  --webapp-name $BACKEND_APP_NAME \
  --resource-group $RESOURCE_GROUP \
  --hostname "api.${CUSTOM_DOMAIN}"
```

### Step 9B: Configure SSL Certificate

**Option 1: App Service Managed Certificate (Free, Recommended)**

```bash
# Create managed certificate for frontend
az webapp config ssl create \
  --name $FRONTEND_APP_NAME \
  --resource-group $RESOURCE_GROUP \
  --hostname $CUSTOM_DOMAIN

# Bind certificate
az webapp config ssl bind \
  --name $FRONTEND_APP_NAME \
  --resource-group $RESOURCE_GROUP \
  --certificate-thumbprint <thumbprint> \
  --ssl-type SNI
```

**Option 2: Import Existing Certificate**

```bash
# Upload certificate
az webapp config ssl upload \
  --name $FRONTEND_APP_NAME \
  --resource-group $RESOURCE_GROUP \
  --certificate-file /path/to/certificate.pfx \
  --certificate-password <password>
```

**Note**: You'll need to update DNS records to point to your App Service. Get the IP address:

```bash
az webapp show --name $FRONTEND_APP_NAME --resource-group $RESOURCE_GROUP --query defaultHostName
```

---

## ✅ Step 10: Verify Deployment

### Check App Status

```bash
# Check backend
az webapp show --name $BACKEND_APP_NAME --resource-group $RESOURCE_GROUP --query state

# Check frontend
az webapp show --name $FRONTEND_APP_NAME --resource-group $RESOURCE_GROUP --query state

# Start apps if needed
az webapp start --name $BACKEND_APP_NAME --resource-group $RESOURCE_GROUP
az webapp start --name $FRONTEND_APP_NAME --resource-group $RESOURCE_GROUP
```

### Test Health Endpoints

```bash
# Backend health check
curl https://${BACKEND_APP_NAME}.azurewebsites.net/api/health

# Frontend
curl https://${FRONTEND_APP_NAME}.azurewebsites.net
```

### View Logs

```bash
# Backend logs
az webapp log tail --name $BACKEND_APP_NAME --resource-group $RESOURCE_GROUP

# Frontend logs
az webapp log tail --name $FRONTEND_APP_NAME --resource-group $RESOURCE_GROUP
```

---

## 🔧 Step 11: Configure Database Schema

If using PostgreSQL, you need to initialize the database schema:

```bash
# Connect to database and run schema initialization
# Option 1: Using psql
psql "postgresql://${DB_ADMIN_USER}:${DB_ADMIN_PASSWORD}@${DB_SERVER_NAME}.postgres.database.azure.com:5432/${DB_NAME}?sslmode=require"

# Option 2: Using Azure Cloud Shell or local script
# The application will create tables automatically on first run
# Or use the migration scripts in backend/scripts/
```

**Note**: The application will automatically create the required database schema on first startup if it doesn't exist.

---

## 📝 Step 12: Update Environment Variables (If Needed)

If you need to update any configuration:

```bash
# Update backend settings
az webapp config appsettings set \
  --name $BACKEND_APP_NAME \
  --resource-group $RESOURCE_GROUP \
  --settings \
    NEW_SETTING=value

# Update frontend settings
az webapp config appsettings set \
  --name $FRONTEND_APP_NAME \
  --resource-group $RESOURCE_GROUP \
  --settings \
    VITE_API_URL="https://${BACKEND_APP_NAME}.azurewebsites.net/api"

# Restart apps to apply changes
az webapp restart --name $BACKEND_APP_NAME --resource-group $RESOURCE_GROUP
az webapp restart --name $FRONTEND_APP_NAME --resource-group $RESOURCE_GROUP
```

---

## 🔄 Step 13: Set Up CI/CD with Automated Deployment

### Azure DevOps Pipeline Setup

The project includes an automated pipeline that builds, pushes, and deploys your application.

1. **Create Service Connections**:
   
   **A) Docker Registry Connection (for building images)**:
   - Go to Azure DevOps → Project Settings → Service connections
   - Create new **Docker Registry** connection
   - Select **Azure Container Registry**
   - Choose your subscription and ACR
   - Name: `zuyderland-cmdb-acr-connection` (or match your variable)

   **B) Azure Resource Manager Connection (for deployment)**:
   - Create new **Azure Resource Manager** connection
   - Select your subscription
   - Name: `zuyderland-cmdb-subscription` (or match your variable)

2. **Configure Pipeline Variables**:
   
   Update `azure-pipelines.yml` with your values:
   ```yaml
   variables:
     acrName: 'cmdbinsightacr'  # Your ACR name
     resourceGroup: 'rg-cmdb-insight-prod'  # Your resource group
     backendAppName: 'cmdb-backend-prod'  # Your backend app name
     frontendAppName: 'cmdb-frontend-prod'  # Your frontend app name
     azureSubscription: 'zuyderland-cmdb-subscription'  # Azure service connection
     dockerRegistryServiceConnection: 'zuyderland-cmdb-acr-connection'
   ```

3. **Create Environment**:
   - Go to **Pipelines** → **Environments**
   - Create environment: `production`
   - (Optional) Add approvals for manual deployment control

4. **Run Pipeline**:
   - Push to `main` branch → **Automatically builds AND deploys**
   - Pipeline will:
     - Build Docker images
     - Push to ACR
     - Deploy to App Services
     - Verify deployment

### Zero-Downtime Deployment (Optional)

For production with zero downtime, use deployment slots:

1. **Create Staging Slots**:
   ```bash
   az webapp deployment slot create \
     --name $BACKEND_APP_NAME \
     --resource-group $RESOURCE_GROUP \
     --slot staging
   
   az webapp deployment slot create \
     --name $FRONTEND_APP_NAME \
     --resource-group $RESOURCE_GROUP \
     --slot staging
   ```

2. **Use Advanced Pipeline**:
   - Use `azure-pipelines-slots.yml` instead
   - Deploys to staging first
   - Swaps to production after verification

**See `docs/AZURE-PIPELINES.md` for complete setup guide.**
