AWS PrivateLink: Private Service Access

The problem with VPC peering and NAT

Accessing a SaaS service or AWS API from a private VPC traditionally required either a NAT Gateway (internet-bound traffic, metered at $0.045/GB) or VPC peering (requires non-overlapping CIDRs, no transitive routing, full VPC exposure).

AWS PrivateLink solves both: traffic stays entirely on the AWS private network, works with overlapping CIDRs, and only exposes the specific service — not the provider's entire VPC.
