> AWS is NOT cheap.

I've realised that cloud costs are a "wave". (App is app/service/business)

- cheap to run as a small app

- costly to run as a bigger app, cheaper to self-host

- cheaper than running all infra for a much bigger app

- extremely costly compared to running all infra for a much-much bigger app

- probably on par with running your own infra (but then you're getting into tens/hundreds of millions of customers)
