**AWS PrivateLink** is the technology behind **interface VPC endpoints**: elastic network interfaces with private IPs in your [subnets](https://www.itwonderlab.com/aws-subnets/) that connect to an AWS service, a partner service or an application that another VPC exposes behind a Network Load Balancer. Traffic stays in the AWS network and needs no [Internet gateway](https://www.itwonderlab.com/aws-internet-gateway/) or [NAT gateway](https://www.itwonderlab.com/aws-nat-gateway/).

Gateway endpoints are a different, free mechanism, only for [S3](https://www.itwonderlab.com/aws-s3/) and [DynamoDB](https://www.itwonderlab.com/aws-dynamodb/).

Interface endpoints are charged per hour per Availability Zone and per GB processed. See [VPC endpoints with Terraform](https://www.itwonderlab.com/terraform-aws-vpc-endpoints/).
