Any reason to use this instead of Ansible? The video shows that this package or script needs to be transported to the host machine before it could be executed or perhaps I understood it wrong.

(Edit) So, I checked out the repository, I personally wouldn't use it or recommend it to anyone. It's a collection of bash scripts, it'd be a pain to debug, log and fix. Ansible playbooks are a much better option. You should be able to version control your deployments and configurations these days.
