Hey all; been ramping up on Pulumi this week and I have one code organization question that hasn't quite been satisfied by the examples code repo. Let's say you have a stack with - a Queue resource, which has - an IAM role group associated, - and an onEvent lambda callback, - which in turn depends on a Table The Table and Queue are used elsewhere. Are there emerging best practices about how to structure your stack into folders and modules to make maintaining these sorts of interconnected systems simpler?
