Why would you commingle development and customer resources? A k8s cluster is just a control plane, that specifically controls where things are running, and if you specify they can’t share resources, that’s the end of that.

If you say they share the same control plane is commingling… then what do you think a cloud console is? And if you are using different accounts there… then I hope you are using dedicated resources for absolutely everything in prod (can’t imagine what you’d pay for dedicated s3, sqs) because god forbid those two accounts end up on the same machine. Heh, you are probably violating compliance and didn’t even know it!

Sigh. I digress.
