No one
needs k8s. Bringing up their infrastructure in a k8s troubleshooting how-to was a weird thing to do in the first place. It's comparing apples and chandelier - makes no sense.
They have a typical vertically scaled infrastructure, most services have just two nodes, one active. The biggest ones are databases which in many companies are handled in "the classic way" anyway. Clearly it's not designed as microservices and doesn't need dynamic automation at all. Why on earth would they even bring k8s up in their plans?
