Hi all, I'm looking for something that will help me model the financial impact of making changes to cloud infrastructure. So for example, in AWS, looking at my group's database estate, wondering if there is an easy way to model (based on the existing infrastructure) what would introducing RDS proxy across all RDS instances do to my monthly bill? Or moving databases to serverless? I might have to do it with a lot of time spent with spreadsheets to do the modelling, but wondering if there's something out there that does this already for me!

Infracost might be worth a shot if you're using Terraform

That's great, and we're actually using it internally already - but I really want to be able to model the change before defining it in Terraform?

What do you mean by modeing? Which visual or textual language? Terraform itself is a model of your infrastructure.

Maybe let's take a concrete example. I have 100 AWS RDS databases which are single AZ, with different engines, instance classes, etc. And all provisioned through Terraform. Let's say I'm looking to enhance my DR posture - so I want to switch half of them to multi-AZ. I'm looking to understand whether there's an easy way to model that financially.
