Question: tools, workflow, etc. for authoring cfn / template.yaml

[pfeilbr]

This is a great example to look at for composing many services together for a non-trivial solution. I've learned a lot from it. Thank you.

When I see cfn templates like template.yaml that composes together many services, I always wonder the development workflow. What tools, workflow, etc. for authoring cfn? Do you use intellisense? A cfn gui? Use something to validate? For the the inline mapping templates, step fn def, is your dev cycle add in cfn, deploy, test, and iterate (seems like it'd be a slow dev/test cycle)? Or do you dev standalone, extract code, and then add to cfn template? Maybe you are very familiar/experienced with cfn and hand code it, but thought I'd ask.

Sorry for all the questions and thank you for this example!
