For me it used to be like that about 4 years ago - everything was built with puppet (ruby). Now people seem to have moved on to ansible.

Perl is nowhere to be seen. Bash still crops up occasionally.

Yeah, that's definitely true, and it depends on the composition of the shop in question. I see Ansible mostly in smaller shops with simpler needs. I see Chef more often once those needs grow a little bit (granted, I also endorse Chef when asked, because I'd rather have a real programming language to better express my intention--Puppet has the same issue). But I see most of that Ruby outside of the CM, dealing with the billion little glue problems involved in cloud crap. Bash too, of course, for obvious reasons.

Now that RedHat bought Ansible and is integrating it with Satellite it's going to be a tough sell in our office if someone wants to use something other than Python for DevOps projects.
