“yet” is the keyword there for sure. It’s not a matter of if, but a matter of when. Even if they’re flushed with cash and grossly over provision their systems, sooner or later, a huge vulnerability will roll around and someone will need to setup / update the OS, ensuring quorum is available for their cluster, fail over traffic during update windows, etc etc etc.
The stacks are getting so insurmountably huge, it’s not possible to just drop a new cluster at their described scale without significantly increasing the workload for an existing team.
