When you are running the Trifacta platform on an EC2 instance, you can leverage your enterprise IAM roles to manage permissions on the instance for the Trifacta platform. When this type of authentication is enabled, Trifacta 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.
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.
