Apple has offered an MDM service for years.
* Until your hidden-from-view postgre SQL db gets corrupted and stops working and all the solutions on the Apple support forums are "couldn't find a fix so just flatten and reinstalled... now moving to Jamf", so every thing in PM is treated like a faberge egg and you're using a kludge of package managers and such to fill in the gaps.
Your 2012 Mac Mini Server in a Sonnet Rackmac needs it's dying 5400rpm HDD switched over to SSDs, which, now you're also using 3rd party hardware + SAS PCIe controllers to connect to a RAID / Tape Drive to keep this thing going.
* Every OS X update is held off because you're trigger shy of the last time it broke OS X Server and your 3rd party SAS controller drivers.
Yet another server to manage on site and/or spend too much $$$ on a boutique "Mac Stadium" data center which is essentially a colo'd Mac Mini.
Jamf Pro is more like Jank Pro but fuck me, it's a million times better than PM.
First time I met our now current Apple Systems Engineer for my region, he laughed when I said I had used PM in the past and said "Uhhh, yeah, don't use Profile Manager in production."
