As use goes up serverless gets more expensive. If you have 20 connections per month, you have to pay for the VM or container running all month even though it's getting no traffic 99% the time. If you have many millions of connections a month and the service is always on and responding, non-serverless will be much cheaper. You could draw a curve of where those two points intersect for each cloud platform. I wonder if anyone has done that. Would be a nice visual. Another drawback of serverless is that it is new so the tooling around it is not as mature as VMs or containers. Stuff like debugging can be pretty rough.
