Management hate classic operation because it's too powerful, it's the operation part of the nervous system of a company, operation can't be managed nor segmented by the management, as a result many try to do their best to delete sysadmins from the scene. Results are that most end up on someone else system with some form of operation. Meaning the cloud. Now that costs skyrocket, issues piling up, no one seems to been able to create a damn full infra well, the push deflate. We have experienced many similar trends: - full stack virtualization on x86, sold as the future, a super-duper simplification, actually a way to allow third party selling pre-made images to those who have no operation or do not own the bare metal (VPS etc); - when people realize how big the overhead is paravirtualization became an old-new trend, mostly with k8s, now this model start to creak and the push toward owning back the infra and the iron start to be noisy I expect in a decade a mainstream NixOS/Guix System move as we had with Ansible/Salt before, the old CFEngine much before and so on, in 20 years probably companies will own back their machine room with a Plan 9 -alike model to just get redundancies and extra temporary resources.
