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.
Benefits
- No internet exposure for sensitive workloads
- Simplified network architecture without VPN or peering
- Granular access control with Endpoint Policies
- Gateway Endpoints for S3 and DynamoDB are free

Frequently Asked Questions
What is AWS PrivateLink?
AWS PrivateLink enables private access to AWS services, SaaS applications, and your own services via VPC endpoints. Traffic stays in the AWS network and does not traverse the internet.
What is the difference between Interface and Gateway Endpoints?
Interface Endpoints use PrivateLink with private IP addresses in your VPC. Gateway Endpoints are free for S3 and DynamoDB and route traffic via route tables. Interface Endpoints cost per hour.
Can I offer my own services via PrivateLink?
Yes, with Endpoint Services you can offer your applications to other AWS accounts or the AWS Marketplace via PrivateLink. The consumer creates an Interface Endpoint in their VPC.
How does PrivateLink improve security?
Traffic stays in the AWS network without internet exposure. You can prevent data exfiltration through VPC endpoint policies and control access to services granularly.
