SL#154 - AWS Services (37/120) - AWS PrivateLink: Endpoints vs Endpoint Services, and a Service Exposed Cross-Account With No Internet Path

PrivateLink is one-way, per-service connectivity: the consumer gets a network interface in its own subnet, the provider gets a load balancer nobody can route to. We will expose a service from a VPC that has no internet gateway, no NAT and no peering, reach it from another VPC, and cost it. Plan for about 45 minutes and under one dollar.
