To me the disparities aren't "how you run your containers". They're "how you resolve the impedance mismatch between managed services that replace systems you have to babysit." Even something as "simple" as SQS is really, really hard to replicate, and attempting to use other cloud providers' queueing systems has impedance mismatch between each other (ditto AMQP, etc., and when you go that route that's just one more thing you have to manage). Running your applications was a solved problem long before k8s showed up.
