CreateCluster

Creates a new cluster with the specified parameters.

To create a cluster in Virtual Private Cloud (VPC), you must provide a cluster subnet group name. The cluster subnet group identifies the subnets of your VPC that Amazon Redshift uses when creating the cluster. For more information about managing clusters, go to Amazon Redshift Clusters in the Amazon Redshift Cluster Management Guide.
