Issue details

As FinOps practice are entering the industry, would be great to be able to extend the Pulumi preview to also show prospective costs of the infrastructure that is about to deploy. Integrating that with CD pipelines would be incredibly useful; complementing that with policy as code and maximum budgets per team will enable FinOps systems to control costs.

I do not see much out there integrating with the Pulumi exports, I saw this: https://cloudcostify.app/, but it's closed source and still private access and this https://www.infracost.io/ for Terraform.

Affected area/feature

I believe this should be part of the different providers (as each cloud will have its own cost API), or a separate extension for each.

Thank you.

Also looping in @ripom who brought this up in a previous conversation.

This has come up a few times internally. We've done some investigation into using policy packs for this, but something more first-class might make sense here as well.

There's an issue to add support for Pulumi on the Infracost side: infracost/infracost#187

Personally, I don't have a preference whether first-class support in Pulumi or extending Infracost makes more sense. 🙂
However, I do miss not having the FinOps capabilities I know from Terraform in Pulumi.
Whenever I have to defend Pulumi, I have to admit that the lack of cost estimation is its weakness and maybe the last big thing missing. 😕
