What is AWS PrivateLink?
AWS PrivateLink enables private access to AWS services, SaaS applications, and your own services via VPC endpoints. Traffic stays entirely in the AWS network and does not pass through the public internet.
PrivateLink solves security and compliance requirements where internet exposure is not acceptable. It also simplifies network architecture since no VPN or peering is needed.
Core Features
- Interface Endpoints: Private IP addresses for AWS services in your VPC
- Gateway Endpoints: Free endpoints for S3 and DynamoDB
- Endpoint Services: Offer your own services via PrivateLink
- VPC Endpoint Policies: Granular access control at service level
- Cross-Account Access: Secure service connection between accounts
Typical Use Cases
AWS Service Access: Access S3, DynamoDB, Lambda, ECR, and other services without Internet Gateway. Meets compliance requirements for isolated workloads.
SaaS Integration: Many SaaS providers in the AWS Marketplace support PrivateLink. Integrate Snowflake, Datadog, or other services without public endpoints.
Multi-Account Architectures: Central services in a Shared Services account can be securely made available to other accounts via PrivateLink.

Interface Endpoints are billed per hour and per GB of data processed, with tiered pricing above certain monthly volumes. Gateway Endpoints for S3 and DynamoDB are free. Current prices are listed on the official pricing page.
How does PrivateLink improve security?
