I mostly don't for new stuff (all in on Docker/ECS), however we have a lot of old stuff and things in the process of being migrated where it makes sense. There's also always the odd bird thing you use that needs to run on a regular host.
Example: How do you do "immutable" management of Mac OS machines? Taking what's typically described as such there, you've just turned a 30s deploy of software into a multi-hour "lets reimage the entire machine"?
(although that's of course not strictly "old stuff")
Were Macs in scope of the original post? I assumed it was server side stuff, rather than office hardware. For that, though, I'd use Jamf (Pro) or some other MDM option.
Even if you exclude "office hardware" from configuration management, our Mac OS build and test farm is "servers" I'd say. Not everyone running servers is doing so to run an online service on a platform of their choice.
I would have to suss out dependency chains on stuff that others built.
Rather than doing that I take a light touch approach with ansible that will suffice until we can dockerize (which would require the same work, but then it’s a dev project vs now when it’s just a devops thing)
