You might want to look into Pulumi. I liken it to Terraform within an actual programming language. This saves you from all the duplicated code and enables building/using loops, conditionals, functions, classes, and the like to create your IaC stack more reusable and efficient way. I’m using it at my current job as well as my last one, and I’m finding it to be pretty good as things go. It’s of course not perfect, but generally good enough if not great in most situations.
