Configure IAM authentication

Configure AWS Identity and Access Management (IAM) authentication and create a minimal Amazon IAM policy for both the EC2 role and Redshift role.
For instructions, see the following How-to-Library article: Configuring AWS IAM Authentication
Note: When you use a serverless runtime environment, you cannot configure IAM authentication.
