Is that still the case with cloud-first, software-defined infrastructure, and IAAS? Even in non-cloud environments you have pets vs. cattle, with the cattle hopefully out-numbering pets. So your data sits off in a storage device, and gets attached to containers running on an OS that is built from a kickstart or similar install. In that case you can spin up VMs running any OS version, make sure you can deploy your containers on it, test it, and off you go. The days of having a fleet of servers that were carefully hand-crafted and evolved over the years are hopefully coming to a close.
