Started Guide. Make a note of the VPC identifier, subnet, and subnet's availability zone.You will

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. If you use the VPC Wizard, a subnet for your VPC is

automatically created for you. For more information about adding a subnet to your VPC, go

to Adding a Subnet to Your VPC.

2. Create an Amazon Redshift cluster subnet group that specifies which of the subnets in the VPC can

be used by the Amazon Redshift cluster.

You can create cluster subnet group using either the Amazon Redshift console or programmatically.

For more information, see Amazon Redshift Cluster Subnet Groups (p. 36).

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

cluster.

To enable a client outside the VPC (on the public Internet) to connect to the cluster, you must 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, go to Security Group Rules in the Amazon

Virtual Private Cloud User Guide.

4. Launch a cluster in your VPC.

You can use the procedure described in the Getting Started to launch the cluster in your VPC. For

more information, see Step 2: Launch a Cluster. As you follow the wizard, in the Configure Network

Options of the ADDITIONAL CONFIGURATION page, specify the following information:

• Choose a VPC Select the VPC from the drop-down list.

• Cluster Subnet Group Select the cluster subnet group you created in step 2.

• Publicly Accessible Select Yes if you want the cluster to have a public IP address that can be

accessed from the public internet, select No if you want the cluster to have a private IP addressed

that can only be accessed from within the VPC. If your AWS account allows you to create

EC2-Classic clusters, the default is no, otherwise the default is yes.

• Choose a Public IP Address Select Yes if you want to select an elastic IP (EIP) address that you

already have configured. Otherwise, select No to have Amazon Redshift create an EIP for your

instance.

• Elastic IP Select an EIP to use to connect to the cluster from outside of the VPC.

• Availability Zone Select No Preference to have Amazon Redshift select the availability zone that

the cluster will be created in. Otherwise, select a specific availability zone.

• Select the VPC security group that grants authorized devices access to the cluster.

The following is an example screen shot of the Configure Networking Options section of the

ADDITIONAL CONFIGURATION page.
