AWS PrivateLink¶
What it is¶
AWS PrivateLink exposes AWS services and customer-operated services as interface VPC endpoints that can be consumed from a consumer VPC over the AWS private network — no internet egress, no NAT, no VPN required.
Role in sovereign-failover topology¶
Named as "the secure cross-partition communication" primitive in the prescribed topology:
"Networking requires isolated Transit Gateways, separate Amazon Route 53 DNS zones, and secure cross-partition communication using AWS PrivateLink." (Source: sources/2026-01-30-aws-sovereign-failover-design-digital-sovereignty)
PrivateLink is the "how do two partitions' VPCs talk to each other's service surfaces over a controlled, policy-enforceable, non-public path" answer, composed with the three cross-partition connectivity options (typically IPsec VPN or Direct Connect under the hood) plus cross-partition auth and cross-signed PKI for the application layer.
