I am managing all my Azure infrastructure using Terraform. So I can destroy module by module...
I have created an hierarchy with several levels of Management Group. From Geographical Zones (Europe, Americas, Asia, ...) to environment (production, staging, ...)
Then I have Subscription for each Business Unit. Each BU could deliver from one to many applications. I am grouping all resources (VNet, Route Tables, AKS, Load Balancer, Database, ...) for each application in a single Resource Group. Meaning that for each BU with only 1 application (almost all BU use case...), I have a 1-to-1 relation between my Resource Group and my Subscription.
I know it's not a problem but I'm wondering if there is a solution to attach more value to the Resource Group. What kind of logic could I implement at that level while I have already split in Geographical Zones, Environment and Business Unit.
Do you see anything that could be relevant here to group resources? Or is that just a last layer that is not really needed in my case?
Thanks
