Amazon Comprehend Medical and interface VPC endpoints (AWS PrivateLink)

You can establish a private connection between your VPC and Amazon Comprehend Medical by creating an interface VPC endpoint. Interface VPC endpoints are powered by AWS PrivateLink, a technology that you can use to privately access Amazon Comprehend Medical 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 Comprehend Medical APIs. Traffic between your VPC and Amazon Comprehend Medical does not leave the Amazon network.

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