Azure Private Link with Virtual WAN
Securely connect your Azure Virtual WAN to Azure PaaS services and on-premises networks without exposing traffic to the public internet.
What is Azure Private Link?
Azure Private Link provides the ability to access Azure PaaS Services (for example, Azure Storage and SQL Database) and Azure hosted customer-owned/partner services over a private endpoint in your virtual network.
Traffic between your virtual network and the service travels the Microsoft backbone network, eliminating exposure to the public internet.
How Azure Private Link Integrates with Virtual WAN
Azure Virtual WAN offers a unified hub-and-spoke architecture for managing network connectivity across your Azure and on-premises environments. Private Link enhances this by enabling:
- Secure Access to PaaS Services: Connect to services like Azure SQL Database, Azure Storage, and Azure Key Vault directly from your Virtual WAN hub or connected virtual networks, bypassing the need for public IP addresses or complex NAT configurations.
- Simplified Network Design: Reduce the complexity of managing firewall rules and network security groups when accessing private services.
- Enhanced Security: Maintain traffic within the Microsoft network for improved data protection and compliance.

- End-to-End Security: Traffic stays on the Microsoft backbone.
- Simplified Management: Integrate seamlessly with Virtual WAN constructs.
- Scalability and Reliability: Leverage the robust Azure network infrastructure.
Common Use Cases
Accessing Azure PaaS
Connect private applications in your spoke VNETs or on-premises to PaaS services without public internet exposure.
Secure Data Access
Enable secure data ingestion and retrieval for services like Azure Blob Storage or Azure Data Lake Storage.
Hybrid Cloud Connectivity
Extend private access for PaaS services to your on-premises applications via Virtual WAN VPN or ExpressRoute connections.
Getting Started
To implement Azure Private Link with Virtual WAN, you typically need to:
- Deploy an Azure Virtual WAN hub.
- Create a Virtual Network Link from your spoke virtual network to the Virtual WAN hub.
- Deploy a Private Endpoint in your spoke virtual network or a dedicated network for Private Link.
- Configure DNS resolution to point to the private endpoint.
