PrivateLink, on the other hand, provides a simpler setup as it only requires the creation of an interface endpoint in the VPC and an endpoint service in the customer&#39;s network.</p> <p><strong>Cost-effective:</strong> PrivateLink pricing is based on the number of requests made to the endpoint service, whereas VPN tunnels are charged based on data transferred over the connection. For customers with large amounts of data transferred, PrivateLink can be a more cost-effective option.</p><div style="clear:both;"></div>
