Azure Private Link architecture isolates API Management, Storage Account, Service Bus Namespace, and Function App within a development VNet (10.0.0.0/22) using dedicated Private Link endpoints and private DNS zones. Traffic flows privately between components—API Management to Storage Account, Function App to Service Bus and Storage Account—without traversing the public internet. This zero-trust network design eliminates data exfiltration risk, enforces least-privilege access via Network Security Group rules, and integrates with Azure Monitor, Key Vault, and Azure AD for compliance and observability.
