Auto-scale using AWS instances using Ansible-Pull with master and slave configuration

Question

I am currently working with AWS instances and want to transfer the entire configuration that is currently running on the AWS master node to several AWS subordinate nodes with only Ansible. Slave nodes may be 2 or 3 or may be larger. Is it possible for the model to ansible-pullautomatically scale the AWS instance when the “Disposal” of the slave node goes down or up?

How can I assign an AWS cluster of nodes?
