Refactoring of terraform project

[Joerg-L]

Hi,
I have a terraform project where refactoring starts to make sense.

Current situation: I have created a module, which deploy all resources to azure for a specific project.

Resources are

• network with subnet and nsgs
• Service bus with queus
• db Server and multiple databases
• aks
• additional vmss
• monitoring
• multiple keyvaults, keys and secrets
• many role assignements

In total round about 400 objects.

This module is used by 4 root modules, one for each environment.

So, I want now to rewrite it, but I'm not sure what the right approach would be.

I guess to implement

• terragrunt or
• terramate or
• combine terragrunt with terramate
  Makes sense related to deployment dependencys.

What are your expirience?
Thanks Jörg
