Resource Orchestration Service (ROS) allows you to check the compliance of a template before you use the template to create resources.
When you use a template to create a stack, the ROS console selects managed rules that match the resources specified in the template to check whether the configuration items of the resources are compliant. For more information, see Create a stack.
