Ask HN: How can I start a Paas like Heroku?

1 points by MarvelousWololo ↗ HN
Even though it sounds silly I'm legitimately curious how can someone start a business like Heroku. I'm not an expert on DevOps but I'd love to have a proof of concept running. Maybe something like Heroku Postgres could be a fun start. I mean the technical details. Is it run on VMs with Kubernetes on something like AWS/GCP/Azure? Thanks!

It's probably just docker and lots of shell scripts to create/configure/delete containers automatically. Well, that's what I'd make if I were trying to recreate heroku. Their system may well be more complex.

Thanks! Do you think it's safe to run production databases on docker containers? I think I've read elsewhere that is not, but as I said I'm a total beginner on DevOps stuff.

I'm getting mixed results from a quick Google search, so either containers have improved for DB use, or there's some specific way you have to use them (maybe both!)
