Somebody needs to choose version of k8s, underlying Linux kernel, system options for this kernel, etc. It is still THE THING, if you try to earn some money and don't have VC money to burn before Google buy you. For example, in place where I work (as developer) operations found good combination of kernel, driver version, NIC chip revision and sysctls, which allows us to use 20% less hardware for our typical load (or allow us to serve 20% more clients on existing hardware without buying new one), and it is substantial for us. Yes, I, as developer, don't need to be system administrator, for me it is containers and CI and automatic deployment, infra as a code, and all this stuff. But somebody NEEDS to build & support this infra. And change faulted SSDs.
