Definition
AWS PrivateLink is a technology that enables private connectivity to AWS services and on premises applications without exposing data to the public internet. It works by creating private endpoints in your virtual private cloud VPC that connect directly to specific AWS services or your own applications hosted elsewhere. This significantly enhances security and compliance by keeping traffic within the AWS network or your private infrastructure. For instance, you can use PrivateLink to access Amazon S3 or DynamoDB from your VPC without traversing the internet. Unlike VPNs or direct connects which establish network tunnels, PrivateLink offers a more streamlined and secure way to access services. This concept is frequently tested on AWS certification exams like the Solutions Architect Associate SAA C03.
