Some resource providers in WrzasqPl-CForm are data providers. It means they do not manage resources but instead load data about existing ones (you can think of them in similar way as in Terraform). CloudFormation doesn't provide such a concept, so they are implemented as regular resource providers and defined as regular resources in your templates, but they do not create anything and will not cause any changes - instead it accesses information about existing resources. Only parameters that the data provider accepts is the resource identifier.

Keep in mind that whenever possible, you should use outputs of your managed records (if you access properties of different stack resources you should use cross-stack references ). Data providers are implemented for properties that are not exposed by default resources.
