AWS Quick elastic network interface

The AWS Quick elastic network interface is a logical networking component in a VPC that represents a virtual network card. Quick creates at least two of these network interfaces to use with a VPC connection based off of the subnets that are attached to it. Then you add the VPC connection to each AWS Quick Sight data source you create. The Quick network interface alone doesn't give Quick direct access to your databases. The VPC connection works only for the AWS Quick Sight data sources that are configured to use it.

When you use the AWS Quick Sight data source to query a database or other instance within your VPC, all the network traffic from AWS Quick originates from this AWS Quick network interface. Because the AWS Quick network interface exists inside your VPC, traffic originating from it can reach destinations within your VPC by using their private IP addresses. Each AWS Quick network interface gets its own private IP address that comes from the subnet you configure. The private IP address is unique for each AWS account, unlike the public IP range.
