Private IP Access to PaaS with Private Endpoint

What a Private Endpoint Is

A private endpoint is a network interface that utilizes a private IP address from an Azure Virtual Network (VNet) subnet to connect securely and privately to a service powered by Azure Private Link.

How It Meets the Requirements

• Keeps traffic off the internet: By projecting the target PaaS service (such as Azure Storage or Azure SQL) directly into the virtual network, communication travels over the Microsoft backbone network rather than traversing the public internet.
• Assigns a private IP: The private endpoint allocates a specific private IP address from your subnet's address range to the destination resource.
• Enhances compliance: Secures sensitive data exchange and meets stringent regulatory isolation standards by eliminating the need for public IP addresses or public internet gateways.

Key Advantages and Capabilities

• Data exfiltration protection: Restricts traffic specifically to the mapped resource instance rather than opening broad access to the entire multi-tenant service.
• Seamless DNS integration: Integrates smoothly with Azure Private DNS zones to resolve standard fully qualified domain names (FQDNs) to the assigned private IP address.
• Hybrid connectivity: Allows on-premises workloads connected via VPN or ExpressRoute to securely reach Azure PaaS resources using internal routing.
• Granular access control: Can be governed with approval workflows across different subscriptions and Microsoft Entra tenants.

Why This Is Optimal

A private endpoint is specifically architected to provide private, non-internet-exposed network connectivity for Azure PaaS resources into a virtual network, making it the standard and optimal architecture for strict corporate security policies.
