Step 3: Configuring the Redshift Cluster


The Additional Configuration page allows you to define a parameter group and encryption settings, set your networking options, and associate a security group with your cluster. For the purposes of this tutorial, we’ll leave most of the default settings as-is.

We'll be focusing on the Configure Networking Options and Security Groups sections.

Configuring networking options

About VPCs...
Every AWS account created after December 3, 2014 includes a default VPC, along with a default publicly acdessible cluster subnet and security group. You do not have to create a VPC if you're fine with using the default.

If you want to use your own, check out Amazon’s Getting Started with VPC guide for a walkthrough. When creating your VPC, remember that Stitch requires a publicly accessible subnet.

First, look at the Choose a VPC option. For the purposes of this tutorial, we're setting this to the default VPC that's included with our account. If you created your own for use with Stitch, select it from the dropdown.

When you select a VPC, the rest of the settings you need to define (don't worry, they're listed below the image) will display. The page should now look like this:

In this section, you need to define these settings:

  • Cluster Subnet Group - Set this to a public subnet in your account - it has to be public for the connection to be successful. The default VPC included with all new AWS accounts also includes a default public subnet, which is what we're using here.
  • Publicly Accessible - This must be set to Yes for Stitch to access your instance.

Selecting security groups

The last step to configuring your cluster is to select a security group to associate with the cluster.

Select the security group that has access to this cluster. Remember, for this tutorial we're using the default security group that's included with all new AWS accounts. We'll edit the access rules for this group in the next section of this tutorial.

When finished, click the Continue button.

What do I do now?

That's it! Note that cluster creation can take a few minutes - the status in the Cluster Dashboard page will change to ‘available’ when the process completes.

The next step in setting up your Redshift cluster is to configure the cluster's authorization, or firewall, settings. In the next section, we'll edit the access rules for the security group associated with this cluster.
