Where do you host apps you built with ChatGPT/Codex once they start getting real traffic?

A developer, having built web apps with ChatGPT/Codex, is seeking advice on hosting solutions as their applications gain real traffic. They are considering options like larger VPS, Ryzen dedicated servers, or cloud platforms such as AWS/GCP. The developer is also interested in the community's perspective on self-managing servers versus paying for managed infrastructure.

This post moves the discussion from initial AI-assisted development to the practicalities of scaling and infrastructure choices once an application gains real-world usage.
