yes Yes YES! One thousand times yes! I previously worked at a SaaS mobile device management company (apperian) that took the on-prem plunge to score big enterprise / government contracts. The ops / support team quadrupled and there were so many headaches. This article nailed it.
Just wait until you're attempting to support a distributed ML system through some fucking idiot sysadmin (well, "sysadmin") who god only knows how he still has a job, but HE CANNOT RELIABLY USE SSH. Because of their security requirements (ie no internets for you, including package servers), getting updated packages onto their 4 year old redhat installs were a nightmare. And they wanted to run very high cpu requirement distributed solvers inside 4gb single processor vms. The fun was just endless.
