Connect to Amazon KMS through a VPC endpoint

You can connect directly to Amazon KMS through a private interface endpoint in your virtual private cloud (VPC). When you use an interface VPC endpoint, communication between your VPC and Amazon KMS is conducted entirely within the Amazon network.

Amazon KMS supports Amazon Virtual Private Cloud (Amazon VPC) endpoints powered by Amazon PrivateLink. Each VPC endpoint is represented by one or more Elastic Network Interfaces (ENIs) with private IP addresses in your VPC subnets.

The interface VPC endpoint connects your VPC directly to Amazon KMS without an internet gateway, NAT device, VPN connection, or Amazon Direct Connect connection. The instances in your VPC do not need public IP addresses to communicate with Amazon KMS.
