Description
An Amazon Redshift cluster consists of nodes. Each cluster has a leader node and one or more compute nodes. The leader node receives queries from client applications, parses the queries, and develops query execution plans. The leader node coordinates the parallel execution of these plans with the compute nodes and aggregates the intermediate results from these nodes. It then finally returns the results back to the client applications. It was detected that the Redshift cluster {AwsRedshiftCluster} does not use enhanced VPC routing. Enhanced VPC routing forces all COPY and UNLOAD traffic between the cluster and data repositories to go through your VPC. You can then use VPC features such as security groups and network access control lists to secure network traffic.
