I'm using AWS free tier and try to create a Redshift cluster, when I select free trial while I'm creating the cluster, I can't attach an IAM role or a security group to the Redshift cluster. Is that meaning I can't do this in the free trial?

CodePudding user response：

The AWS Free Tier for Amazon Redshift provides 750 DC2.Large node hours per month for 2 months.

The "Free trial" configuration in the Amazon Redshift console provisions a matching cluster. You are correct that it offers minimal configuration options. However, you can modify the cluster after it is launched and attach an IAM Role and change Security Group.

Alternatively, launch the cluster via the Production option and simply make sure that you have selected a dc2.large node. You will not be billed for the first 750 node hours per month for two months.
