It's JSON, not YAML
Yes. But the cloudformation designer will convert it automatically if it is valid JSON. It does if I enclose the current JSON with {}. Even the JSON linter needs it.
It's not a full cloudformation script, only a partial snippet. You have to fit it into a bigger one
InternetFacingRouteTable and many other resources are missing

Looks awesome, very simple to port to Terraform as well.
Are there any lessons learned from the pattern? At time of this comment no revisions have been made and it's been over a year since publication. In any-case this is a great example of clean infrastructure provisioning. Thank you for your contribution.
