Amazon Transcribe and interface VPC endpoints (AWS PrivateLink) - Amazon Transcribe

Amazon Transcribe and interface VPC endpoints (AWS PrivateLink)

You can establish a private connection between your VPC and Amazon Transcribe by creating an interface VPC endpoint. Interface endpoints are powered by AWS PrivateLink, a technology that enables you to privately access Amazon Transcribe APIs without an internet gateway, NAT device, VPN connection, or AWS Direct Connect connection. Instances in your VPC don't need public IP addresses to communicate with Amazon Transcribe APIs. Traffic between your VPC and Amazon Transcribe does not leave the Amazon network.

Each interface endpoint is represented by one or more Elastic Network Interfaces in your subnets.

For more information, see Interface VPC endpoints (AWS PrivateLink) in the Amazon VPC User Guide.
