I've heard about "CloudFormer" tool, to automatically generate a base template from existing resources on the cloud. https://medium.com/@ridmag/how-to-use-aws-cloudformer-e8d848cfafe1
I can't find this tool in aws! Perhaps this is a old tool that has been removed?
I've heard about another not-Amazon product named "terraform.io" as well. Can Terraform do this? Can it produce a template (in its proprietary format and/or in the cloudformation format) as well?
