When you are running the Designer Cloud Powered by Trifacta platform on an EC2 instance, you can leverage your enterprise IAM roles to manage permissions on the instance for the Designer Cloud Powered by Trifacta platform. When this type of authentication is enabled, Alteryx administrators can apply a role to the EC2 instance where the platform is running. That role's permissions apply to all users of the platform.
IAM roles
Before you begin, your IAM roles should be defined and attached to the associated EC2 instance.
NOTE: The IAM instance role used for S3 access should have access to resources at the bucket level.
