2 years ago There is usually one but sometimes a couple of providers in large-terraform infrastructure. It does not make a lot of sense to move them outside unless there is a large amount of code. I don't think it has to be described in the book.

If you have to specify many aws regions as aliases, you will get lost with where the actual work is (the modules down below).
Reconsider where to put the provider blocks; eg, new file called providers.tf
