AWS PrivateLink and VPC Endpoints

AWS PrivateLink

AWS PrivateLink is a VPC-based service that creates a private connection between VPCs, AWS services, and on-premises resources in an AWS Region. Using PrivateLink, we can connect services in one AWS account, different accounts, and AWS partner-supported services. It uses the AWS private network for communication, so the traffic never goes to the public internet. We don’t need a NAT gateway, IGW, or AWS Direct connection to connect to the resources in a private subnet.
