Hi AgitatedDove14 , what I meant is that if it is possible to associate ec2 instances of the autoscaler to a IAM role in order to grant permissions to applications running on that instances, which could be for example the access to a s3 buckets that can be accessed only with a certain IAM role permissions. I'm not completely sure that what I'm saying makes sense, but I refer to something similar as it's specified here https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-ec2.html
