With this feature you can now access S3 directly as a private endpoint within your secure, virtual network using a new interface VPC endpoint in your Virtual Private Cloud. This extends the functionality of existing gateway endpoints by enabling you to access S3 using private IP addresses. API requests and HTTPS requests to S3 from your on-premises applications are automatically directed through interface endpoints, which connect to S3 securely and privately through PrivateLink.
Interface endpoints simplify your network architecture when connecting to S3 from on-premises applications by eliminating the need to configure firewall rules or an internet gateway. You can also gain additional visibility into network traffic with the ability to capture and monitor flow logs in your VPC. Additionally, you can set security groups and access control policies on your interface endpoints.
PrivateLink for S3 is available in all AWS Regions. AWS PrivateLink is available at a low per-GB charge for data processed and a low hourly charge for interface VPC endpoints. We hope you enjoy using this new feature and look forward to receiving your feedback. To learn more, check out the PrivateLink for S3 documentation.
