Expected Outputs

  1. Azure CLI Scripts:

    #!/bin/bash
# Create resource group
az group create \
  --name myapp-prod-rg \
  --location eastus \
  --tags Environment=Production Project=MyApp

# Create storage account

  --kind StorageV2 \
  --https-only true \
  --min-tls-version TLS1_2

  2. ARM Templates (when not using Terraform):

    {
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "resources": [
    {
      "type": "Microsoft.Storage/storageAccounts",
      "apiVersion": "2023-01-01",
      "name": "[parameters('storageAccountName')]",
      "location": "[parameters('location')]",
      "sku": {
        "name": "Standard_LRS"
      },
      "properties": {
        "minimumTlsVersion": "TLS1_2"
      }
    }
  ]
}

  3. Networking Architecture:

    # Azure Networking Design
VNet: myapp-vnet (10.0.0.0/16)
  Subnets:
    - app-subnet: 10.0.1.0/24
      - Network Security Group: app-nsg
      - Service endpoints: Microsoft.Storage
    - data-subnet: 10.0.2.0/24
      - Network Security Group: data-nsg
      - Private endpoints

  4. RBAC Configuration:

    # Assign role to managed identity
az role assignment create \
  --role "Storage Blob Data Contributor" \
  --assignee-object-id $IDENTITY_ID \
  --scope $STORAGE_ACCOUNT_ID \
  --assignee-principal-type ServicePrincipal

  5. Resource Naming Guide:

    # Azure Naming Convention
Resource Groups: {project}-{environment}-rg
Storage Accounts: {project}{env}storage (no hyphens, lowercase)
App Services: {project}-{environment}-app
Key Vaults: {project}-{environment}-kv
VNets: {project}-{environment}-vnet
Subnets: {purpose}-subnet

  6. Configuration Files:

    // appsettings.json for Azure integration
{
  "AzureAd": {
    "Instance": "https://login.microsoftonline.com/",
    "TenantId": "your-tenant-id",
    "ClientId": "your-client-id"
  },
  "Storage": {
    "ConnectionString": "UseManagedIdentity=true;AccountName=myappstorage"
  }
}

Best Practices

Azure Resource Organization

  1. Resource Groups: Logical grouping by lifecycle

    • Group resources that share same lifecycle
    • Use consistent naming: {project}-{environment}-rg
    • Tag with Environment, Project, CostCenter

  2. Subscriptions: Separate by environment or department

    • Dev/Test subscription (lower costs)
    • Production subscription (isolated)
    • Management groups for policy enforcement

  3. Regions: Choose based on data residency and latency

    • Primary: eastus, westus, westeurope
    • Secondary: For disaster recovery
    • Multi-region: Use Front Door or Traffic Manager

Networking Best Practices

  1. VNet Design: Plan address space carefully

    • Use RFC 1918 ranges (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16)
    • Leave room for growth
    • Document subnet purposes

  2. Network Security Groups: Least privilege

    • Deny all by default
    • Allow specific ports only
    • Use service tags (e.g., AzureCloud)

  3. Private Endpoints: For sensitive services

    • Storage accounts
    • Key Vault
    • Database services

Security Best Practices

  1. Managed Identities: Prefer over service principals

    • No credentials in code
    • Automatic rotation
    • Integrated with RBAC

  2. Key Vault: For all secrets

    • Never hardcode secrets
    • Use Key Vault references in App Service
    • Enable soft delete and purge protection

  3. RBAC: Least privilege principle

    • Use built-in roles when possible
    • Assign at lowest scope needed
    • Regular access reviews

  4. Encryption: Enable everywhere

    • Storage: Encryption at rest (default)
    • Networking: HTTPS/TLS only
    • Databases: Transparent data encryption

Performance and Cost Optimization

  1. Storage: Choose correct tier

    • Hot: Frequently accessed
    • Cool: Infrequently accessed (30+ days)
    • Archive: Rarely accessed (180+ days)

  2. Compute: Right-size resources

    • Start small, scale up if needed
    • Use autoscaling where possible
    • Consider reserved instances for production

  3. Monitoring: Track costs

    • Use Azure Cost Management
    • Set budget alerts
    • Tag resources for chargeback

Workflow

  1. Read Requirements: Understand Azure services needed
  2. Design Architecture: Resource groups, networking, compute, storage
  3. Create Naming Convention: Consistent resource naming
  4. Write Provisioning Scripts: Azure CLI or ARM templates
  5. Configure Networking: VNets, NSGs, private endpoints
  6. Set Up Identity: Managed identities, RBAC assignments
  7. Configure Security: Key Vault, encryption, HTTPS
  8. Add Monitoring: Application Insights, Log Analytics
  9. Document: Architecture diagram, naming guide, runbook
  10. Output Artifacts: Scripts, templates, configuration files

Critical Gotchas to Avoid

Gotcha #1: Storage Account Naming

Problem: Storage account names have strict requirements Solution: Follow Azure naming rules

# ❌ WRONG - Invalid storage account name
az storage account create --name my-app-storage-prod  # Hyphens not allowed

# ✅ RIGHT - Valid storage account name
az storage account create --name myappstorageprod  # Lowercase, no hyphens, 3-24 chars

Gotcha #2: Missing HTTPS-Only

Problem: Storage/services allow HTTP, security vulnerability Solution: Always enforce HTTPS

# ❌ WRONG - HTTP allowed (default in older versions)
az storage account create --name myappstorage

# ✅ RIGHT - HTTPS required
az storage account create \
  --name myappstorage \
  --https-only true \
  --min-tls-version TLS1_2

Gotcha #3: Public Network Access

Problem: Services exposed to internet by default Solution: Use private endpoints for sensitive resources

# ✅ Disable public network access
az storage account update \
  --name myappstorage \
  --resource-group myapp-rg \
  --public-network-access Disabled

# ✅ Create private endpoint
az network private-endpoint create \
  --name storage-pe \
  --resource-group myapp-rg \
  --vnet-name myapp-vnet \
  --subnet data-subnet \
  --private-connection-resource-id $STORAGE_ID \
  --group-id blob \
  --connection-name storage-connection

Gotcha #4: Hardcoded Credentials

Problem: Credentials in code or configuration files Solution: Use managed identities

// ❌ WRONG - Hardcoded connection string
var connectionString = "DefaultEndpointsProtocol=https;AccountName=...;AccountKey=...";

// ✅ RIGHT - Managed identity
var credential = new DefaultAzureCredential();
var blobClient = new BlobServiceClient(
  new Uri("https://myappstorage.blob.core.windows.net"),
  credential
);

Gotcha #5: Overly Permissive NSG Rules

Problem: Wide-open network security groups Solution: Specific ports and sources only

# ❌ WRONG - Allow all traffic
az network nsg rule create \
  --nsg-name myapp-nsg \
  --name allow-all \
  --priority 100 \
  --source-address-prefixes '*' \
  --destination-port-ranges '*' \
  --access Allow

# ✅ RIGHT - Specific ports and sources
az network nsg rule create \
  --nsg-name myapp-nsg \
  --name allow-https \
  --priority 100 \
  --source-address-prefixes 'Internet' \
  --destination-port-ranges 443 \
  --access Allow \
  --protocol Tcp

Gotcha #6: Missing Resource Tags

Problem: Cannot track costs or ownership Solution: Always tag resources

# ✅ Tag all resources
az group create \
  --name myapp-prod-rg \
  --location eastus \
  --tags \
    Environment=Production \
    Project=MyApp \
    CostCenter=Engineering \
    Owner=team@company.com
