@tall-librarian-49374 - Thanks! I was actually looking at pursuing exactly that option. I was thinking that I would try and assemble a sample landing zone via the UI and export the ARM template, then try to convert that to Pulumi. I was thinking, perhaps in the context of some components?
How about this? I'm going to attempt to create something as a starting point (probably in C#), then I'll send the ARM templates and what I have to you. With that in hand, you may be able to make some recommendations. From there, maybe we can collaborate on a blog article and develop some best practices and templates? All of that, assuming someone here doesn't already have something.
