Where to start with a mess?

• terraformer

  CLI tool to generate terraform files from existing infrastructure (reverse Terraform). Infrastructure to Code

  

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.
