1. The document discusses how to configure a Network Load Balancer (NLB) with a PrivateLink endpoint to provide private access to services within a VPC. 2. Key steps include creating an Elastic Network Interface (ENI) in each Availability Zone, associating the ENIs to the NLB, and specifying the PrivateLink endpoint DNS name to route traffic privately. 3. PrivateLink allows networking interfaces and resources to be accessed privately without an internet gateway, NAT device, VPN connection or AWS Direct Connect.
