Are those the same Pulumi "project" but different Stacks?

This one. If it’s the same infrastructure but different configs (dev, prod, etc) it’s one project and different stacks. A different project would be something that stands up completely different resources

Well I mean, I am standing up completely different resources, they just both solve the same problem

Right. I think that they both solve the same problem is the key

That's fair

I also don’t work for Pulumi so don’t let me speak for them 😄

ofc 🙂 I feel like there are pros and cons to both approaches

Ya, but to me maintaining two different versions of the same thing of the same thing is easier in one project than it is in two. I’m sure there is some overlap between the two?

No, they're completely different - peep https://github.com/ruheapp/hasura-docker/blob/azure-prod/infra-dev/index.ts vs https://github.com/ruheapp/hasura-docker/blob/azure-prod/infra-prod/index.ts

Ya, stuff like

pguser

and

pgname

etc
