PrivateLink

AWS PrivateLink enables private connectivity between VPCs and AWS services (or partner services) without exposing traffic to the public internet. Traffic traverses the AWS backbone network through VPC endpoints, eliminating the need for internet gateways, NAT gateways, or public IP addresses for service-to-service communication.

PrivateLink is essential for meeting data sovereignty requirements, reducing internet exposure of sensitive service endpoints, and connecting SaaS services into customer VPCs securely.
