3.3.3. App Service and Azure SQL Network Integration

💡 First Principle: PaaS services like App Service and Azure SQL have unique networking considerations because they're multi-tenant by default. Network integration options vary by service tier.

App Service Network Integration

FeatureStandard/PremiumIsolated (ASE)
VNet Integration (outbound)YesYes
Private Endpoint (inbound)YesYes
Deploy directly in VNetNoYes

⚠️ Exam Trap: Thinking you can deploy a Standard tier App Service directly into a VNet subnet. Only the Isolated tier (App Service Environment) can be deployed directly into a VNet. Standard tier uses VNet Integration for outbound and Private Endpoints for inbound.

Azure SQL Managed Instance

  • Deployment: Directly into a VNet subnet
  • Requirement: Dedicated subnet with specific delegation
  • Network security: NSGs applied to the subnet
