Frequently Asked Questions
- What is the difference between Private Link and VPN?
- Private Link provides private access to specific cloud services within the cloud provider network. VPN creates encrypted tunnels between networks (typically on-premises to cloud). Private Link is simpler and lower-latency for accessing cloud-native services.
- Does Private Link encrypt traffic?
- Private Link keeps traffic on the cloud provider private backbone, which is inherently isolated. For additional encryption, you can layer TLS on top. The key benefit is that traffic never touches the public internet.
