You see this is too complicated and "If you do it right" imply you can get it wrong and go bankrupt. I prefer to use dedicated server with dedicated bandwidth and Kubernetes on top of that. This makes me sleep comfortably at night. I tried the cloud and this was just too much anxiety for me to handle.
It is absolutely not complicated compared to running Kubernetes yourself. You don't have to use serverless and infinite scaling. For things like Azure App Services you don't autoscale to start with and if you want autoscaling it looks like this:
Yes, just like driving, if you doing it wrong you got to the hospital or die, if you doing it the right way you get from A to B. Personal responsibility does not go away because you are using the cloud.
