Private Link
Private Link is a cloud networking service that enables secure, private connectivity between virtual networks and services without exposing data to the public internet. It allows resources like virtual machines, databases, or storage to be accessed privately over a Microsoft-managed backbone network, enhancing security and reducing data exfiltration risks. This service is commonly offered by cloud providers, such as Azure Private Link, to facilitate hybrid and multi-cloud architectures.
Developers should use Private Link when building applications that require secure, low-latency access to cloud services without public internet exposure, such as in financial, healthcare, or government sectors with strict compliance needs. It is ideal for scenarios involving sensitive data transfers, hybrid cloud integrations, or connecting on-premises resources to cloud platforms while maintaining network isolation and reducing attack surfaces.
