6.4 Billing for PrivateLinks

There are no surcharges for using Query PrivateLinks for Highly Available DB Systems when compared to standalone DB Systems. In contrast, when creating an Egress PrivateLink for high availability target DB System(s), you are billed for three Egress Endpoints because an Egress PrivateLink is comprised of three VPC Endpoints inside HeatWave on AWS.

Also note that when Configuring the Network Infrastructure for an Egress PrivateLink, enabling Cross-Zone Load Balancing for your Network Load Balancer may incur surcharges for your AWS account.
