Amazon S3 simplifies private connectivity from on-premises networks

Virtual Private Cloud (VPC) interface endpoints for Amazon S3 now offer private DNS options that can help you more easily route S3 requests to the lowest-cost endpoint in your VPC. With private DNS for S3, your on-premises applications can use AWS PrivateLink to access S3 over an interface endpoint, while requests from your in-VPC applications access S3 using gateway endpoints. Routing requests like this helps you take advantage of the lowest-cost private network path without having to make code or configuration changes to your clients.
