Once you have enabled CloudyCluster in the AWS Marketplace, you can launch CloudyCluster without using Cloud Formation. You can create your own IAM role and select it when you launch the AMI from the EC2 Console.  The IAM role needs to be created with the following permissions (you can just paste these in when you create the role).
