I use Fly.io, it’s not serverless at all, it’s a PaaS that manages your servers for you via its own automations and cli. Fly also already supports postgres (I use this too) so I’m not sure why I would use this? To me the whole point of Fly is minimal work :)

When you say it like that, nothing really is serverless. Everything is running on some computer.

Serverless architectures are provided by servers.

Serverless is like AWS lambda, when you don’t have an explicitly running VM that you pay per time; instead your code is run in “a cloud” and you pay per invocation.

This is nothing new! “Serverless” is well defined and understood for years and years!

This is actually what Fly machines do under the covers. When you use it as a PaaS, the client CLI sets all this up for you, and then our proxy starts/stops things as needed.
