What people don't get about salt, is that its literally kubernetes (as in orchestrator) for your infrastructure.
It takes the "operator" concept to a very new level: You can tell it to react automatically and enlarge a disk in a machine due to space constrains, reschedule workloads according to load, configure a loadbalacner according to rules you write once, create resiliency rules, deploy new machines or containers...
It scales ridiculously, i have seen 30000 minions to a master.
Why you would use it via ssh other than bootstrapping is beyond me...
btw: you can run ansible via the salt bus transport = salstack in the ansible.cfg, be amazed.
