aztfy VS terraforming

Aztfy is a tool developed by Microsoft that allows you to bulk import resources, it has some configuration so you can specify what to import, the names to import and so on. After spending some time with the tool, I quickly realized it may be a no-go. The problem I had with this tool is twofold:

Azure Terrafy is a tool that makes it easy to import your existing Azure resources into Terraform modules. Suppose you're an Azure user looking to manage your infrastructure with the power of Terraform. In that case, Azure Terrafy can save you time and effort by automating the process of incorporating your existing resources into your Terraform configuration. This is especially useful for those who have a "brownfield" environment, where their infrastructure already has a number of existing resources that need to be brought under the management of Terraform. It can save you a lot of time and effort. Without Terrafy, you would need to manually create a Terraform configuration file for each resource you want to manage. This can be tedious and error-prone, especially if you have many resources.

If that existing infrastructure happens to be in Azure, look into aztfy, it's helped me build some structures to replace first-generation hand-deployed resources.

Terraforming

I would also strongly recommend an iterative triage process: don't feel that you need to solve everything all once. It's a huge amount of progress if you can get to a stage where you understand the relationships between services, have enough monitoring to identify failures, and can iteratively move services to more granular IAM policies even if it's all still running in one big account. Simply using a tool like terraformer or terraforming to move the manual configuration into an IaC workflow is an accomplishment, especially since it helps you both make changes more confidently and identify where new changes are still being made. Depending on the politics, that last part might be important: you'll be unpopular if you take away everyone's rights but you'll probably have better luck first nudging people to make them using a sensible flow rather than by hand.

Haven't tried this but if I ever find myself in your situation I'll give it a spin https://github.com/dtan4/terraforming

There are a couple of tools to automate creating terraform configuration and prepopulate state from existing resources, like terraforming, terraformer or cf-terraforming. But it is still cumbersome and laborious and in my experience, it's usually way easier to just recreate everything within terraform from scratch wherever that's possible.

🧪 Terraforming export existing AWS resources to Terraform style (tf, tfstate).
