You can now use Amazon Redshift’s Enhanced VPC Routing to force all of your COPY and UNLOAD traffic to go through your Amazon Virtual Private Cloud (VPC). Enhanced VPC Routing supports the use of standard VPC features such as VPC Endpoints, security groups, network ACLs, managed NAT and internet gateways, enabling you to tightly manage the flow of data between your Amazon Redshift cluster and all of your data sources. In particular, when your Amazon Redshift cluster is on a private subnet and you enable Enhanced VPC Routing, all the COPY and UNLOAD traffic between your cluster and Amazon S3 will be restricted to your VPC. You can also add a policy to your VPC endpoint to restrict unloading data only to a specific S3 bucket in your account, and monitor all COPY and UNLOAD traffic using VPC flow logs.
