Personally I'd much rather see a GUI that can help string together snippets of Terraform/CFN and Ansible/Chef/Puppet/Salt/whathaveyou. A visual IDE for infrastructure automation, if you will.
So the idea is that you would choose your changes in the GUI, but instead of actually changing the target, it spits out the required code to do it for you in a repeatable way? I would definitely find that useful for Terraform and Cloudformation. Searching for it, I see that AWS has a tool targeted at that: Cloudformation Designer. https://aws.amazon.com/blogs/aws/new-aws-cloudformation-desi... https://docs.aws.amazon…
To be really useful, it should have some kind of snippet options (insert a vpc with all the usual subnets, routing, etc in one go), or some "fill in the blanks" functionality.
