It always make me both roll my eyes and smile a little when i see someone daft enough to think they need some obscene setup - you dont. You never have. You are not Amazon, Microsoft, Google, etc. If you get to the point where you need that kind of setup you're already employing a dev ops team thats telling you that.

Stick whatever you're working on onto a ~$5/mo cheapo vps from someone like Hetzner, Digitalocean, etc and just get on with building your thing.
