Infrastructure Security

  • Amazon QuickSight is delivered as a web application, hosted on dedicated Amazon EC2 hosts, separate from AWS virtual private clouds (VPCs). 
  • Amazon QuickSight is accessed through Regional public endpoints. 
  • The database server, which is QuickSight’s data source, must be accessible from the Internet and allow inbound traffic from QuickSight servers.
  • You can create a VPC connection in QuickSightby by adding an ENI to your VPC. This feature is available on EE only.
    • This will allow cross-region or cross-account connection through:
      • VPC Sharing
      • Transit Gateways
      • Private Link
  • For QuickSight to connect to an Amazon Redshift instance, the Amazon Redshift must have in its SG inbound rule that allows the public CIDR IP of QuickSight in that region.
