How does AWS PrivateLink enhance security in VPC?
Within a VPC, AWS PrivateLink enhances security by creating a VPC Endpoint (Interface Endpoint) that places Elastic Network Interfaces (ENIs) with private IPs in your subnets. Your resources communicate with the service through these private IPs instead of traversing the internet.
This is why PrivateLink is often preferred over VPC Peering when the requirement is to securely access a specific service rather than establish full network connectivity between VPCs.
