That's a fair remark. I think the biggest scale I've operated at was maybe a few million customers, consumer and business, for Flight Centre, which is a travel agent that serves pretty much the entire of Australia and overseas too. A few big banks too. None of them used K8s at the time and operated fine. Might have drank the kool aide by now, though.

I think scale has less to do with how many customers you're serving and more to do with how much data you're processing. Streaming video to 10,000 people is much more data-intensive than exposing a CRUD interface to 1M.

Also k8s is not, in and of itself, a complication. You're going to have to worry about the same set of problems whether or not you use k8s. Deployments, load-balancing, self-healing, etc. It's not like ops teams didn't do anything before k8s came along.

Not necessarily true, the complication that k8s brings isn't the same that other implementations bring. More moving parts in a highly pluggable architecture brings with it more opinions and optimisations and overhead. Also managed services exist which means several specific issues don't exist. The ops teams simply do something else.

I’ve yet to find a problem that two servers and a load balancer can’t resolve — see the above scales I’ve worked at. All simple setups.
