I once took a job that involved managing Ansible playbooks for an absolutely massive number of servers that would run them semi-regularly for things like bootstrapping and patching. I had used Chef before for a similar task, and I loved it because it's just ruby and I could easily define any logic I wanted while using loops and proper variables.

I understand that Ansible was designed for non-programmers, but there is no worse hell for someone who is actually familiar with basic programming than being confined to the hyper-verbose nonsense that is Jinja templating of Ansible playbooks when you need to have a lot of conditional tasks and loops.
