Redshift enhanced VPC routing

  • When you use Redshift Enhanced VPC Routing, Redshift forces all COPY and UNLOAD traffic between your cluster and your data repositories through your VPC.

  • By using Enhanced VPC Routing, you can use standard VPC features, such as VPC security groups, NACLs, VPC endpoints, VPC endpoint policies, internet gateways, and DNS servers.

    • You use these features to tightly manage the flow of data between your Redshift cluster and other resources.

  • If Enhanced VPC Routing is not enabled, Redshift routes traffic through the Internet, including traffic to other services within the AWS network.
