No, not following. I understand how master based provisioning management systems had their time and place, but we've largely moved beyond that to baking images, whether containers or VMs. Running a master based system comes with a whole house of other issues. Ansible is now relegated to a better system than based for installing packages and configuring the baked image. The time of booting a vanilla imstamce and then installing software when a scaling events happens is over.

By the way, what does ansible do to help with scaling applications?
