Agree, I would never want to go back to the old bad days of managing a real rack at a datacenter, with exactly the same guarantees of a single region deployment inside any cloud. BUT it is true that all the multi region/AZ guarantees + logs + dashboards + network services @ AWS costs tend to skyrocket in a couple of years. And here is where k8s really shines, in my opinion: allowing you to abstract your deployment away from a cloud even on cheap hosting. All the rest outlined in the article is just reinventing the wheel.

Usually those aren't the same engineers that manage the racked stuff in a datacenter and those that deploy the appps.

Last time I was working on prem, we would just buy a new 2U hypervisor server once in a while. Apps were all running on VMs anyway so the complexity was not seen by the same people. Storage were a multiple years deal. The biggest issue was storage estimation and paying from day 1 a storage that would be used fully only on year 5. But I don't think it was that expensive, just an accountability gymnastic comparing to a pay as you go system. And hyperconvergence was kind of meant to solve that although I didn't really had the chance to experiment with it in virtualized environments on prem.
