I'm use to Saltstack and I'm interessted now by Ansible.
But among all the questions I have, I didn't find anything regarding the Highstate (in Salt terminology). I use it to ensure my infrastructure is always at the desire state and to detect any anomaly if it's not.
What is the equivalent concept for that with Ansible ?
Salt's states system is very similar to Ansible's approach.
Is Ansible's playbook suitable for you? You can define highstate.yml playbook and apply necessary changes.
