This is why I don't use those serverless setup.

$4 hetzner vps can serve tons of request if you put cloudflare in front of it

I host my own runners for CI and artifcat building on Hetzner VPS (spun on demand).

People are easily lured by pay as you go plans on serverless and other cheap to get started managed services and end up racking huge bills.

This is same reason I don't use stack driver or cloud monitoring and prefer to use graphana + loki + Prometheus setup

My setup cannot be misconfigured and end up racking huge bills.
