Managing cluster subnet groups using the console

You can manage your cluster subnet groups using the Amazon Redshift console. You can create a cluster subnet group, manage an existing one, or delete one. All of these tasks start from the cluster subnet group list. You must select a cluster subnet group to manage it.

You can provision a cluster on one of the subnets that you provide the subnet group. A cluster subnet group enables you to specify a set of subnets in your virtual private cloud (VPC).

Creating a cluster subnet group

You must have at least one cluster subnet group defined to provision a cluster in a VPC.

To create a cluster subnet group

  2. On the navigation menu, choose Configurations, then choose Subnet groups. The list of subnet groups is displayed.

  3. Choose Create cluster subnet group to display the create page.

  4. Enter information for the subnet group, including which subnets to add.
