Amazon Elastic Container Service (ECS) and Amazon Elastic Container Registry (ECR) now have support for AWS PrivateLink. AWS PrivateLink is a networking technology designed to enable access to AWS services in a highly available and scalable manner, while keeping all the network traffic within the AWS network. When you create AWS PrivateLink endpoints for ECR and ECS, these service endpoints appear as elastic network interfaces with a private IP address in your VPC.
