Azure Private Link is a service that enables customers to access Azure PaaS services (e.g. Azure Storage, Azure SQL, Azure Cosmos DB) over a private endpoint in their virtual network.
This provides the following benefits:
- Secure connectivity: By using private endpoints, all network traffic between the customer’s virtual network and the Azure PaaS service stays within the Microsoft network, reducing the attack surface and reducing the need for a VPN connection or ExpressRoute.
- Compliance: By using private endpoints, customers can meet compliance requirements by keeping all data within their own virtual network.
- Reducing egress data costs: By using private endpoints, customers can reduce or eliminate data transfer costs when accessing Azure PaaS services from their virtual network.
- Improved performance: By using private endpoints, customers can improve the performance of their applications by reducing the network latency and reducing the number of network hops.
Additionally, Azure Private Link also allows customers to expose their own Azure services over private endpoints, allowing other customers to access their services over a private link. This enables customers to share their services with others in a secure and controlled way.
Overall, Azure Private Link is a service that enables customers to access Azure PaaS services over a private link in their virtual network, providing security, compliance, cost reduction and performance improvement.
