Creating a cluster in a VPC

To create a cluster in a VPC

1. Set up a VPC.

   You can create your cluster either in the default VPC for your account, if your account has one, or a VPC that you have created. For more information, see Use EC2-VPC when you create your cluster. To create a VPC, see Create a VPC in the Amazon VPC User Guide. Make a note of the VPC identifier, subnet, and subnet's Availability Zone. You need this information when you launch your cluster.

   Note

   You must have at least one subnet defined in your VPC so you can add it to the cluster subnet group in the next step. For more information about adding a subnet to your VPC, see Adding a subnet to your VPC in the Amazon VPC User Guide.

2. Create an Amazon Redshift cluster subnet group to specify which subnet your Amazon Redshift cluster can use in the VPC.

   You can create a cluster subnet group using either the Amazon Redshift console or programmatically. For more information, see Amazon Redshift cluster subnet groups.

3. Authorize access for inbound connections in a VPC security group that you associate with the cluster.

   You can enable a client outside the VPC (on the public internet) to connect to the cluster. To do this, you associate the cluster with a VPC security group that grants inbound access to the port that you used when you launched the cluster. For examples of security group rules, see Security group rules in the Amazon VPC User Guide.

4. Follow the steps in Amazon Redshift provisioned clusters in the Amazon Redshift Getting Started Guide to create a cluster. Make the following modifications when creating your cluster:

   • To display the Additional configurations section, switch off Use defaults.

   • In the Network and security section, specify the Virtual private cloud (VPC), Cluster subnet group, and VPC security group that you set up.
