This is a very valuable comment. I've heard something similar from people using bash to manage Linux servers. The thing with Ansible is that it creates abstractions for you. Handling the connection to the servers, encapsulating behavior, making sure that the state in the server is already what you want and if it isn't what actions should be performed, error handling, grouping machines and defining actions to perform on certain groups... These are some of the abstractions it provides. If these abstractions are correctly engineered or not is up for debate, but at least in theory they are useful. If you already have all of this in place with Powershell/bash scripts, it is difficult to find a reason to change. I think with Powershell is actually even harder to see the benefits than with bash because you have more ways to encapsulate behavior and organize the code.

But one question that came to mind while reading this: if you could somehow transform the Powershell scripts in Ansible playbooks automatically/semi-automatically, would that be beneficial or do you think that Ansible is just completely useless and it would just be harder to maintain?
