We both agree that orchestration is critical. Yet orchestrators are fairly new, the docker hype was strong long before they were viable, or existed at all.

You'll forgive me but implying that one one should just use an orchestrator points to one ignoring their history -or lack thereof-.

I have seen entire clusters taken out by a regression. Sadly, even the best orchestration cannot do much better than the core it is running on. You can google "docker in production" to get more substance.
