For demo purposes and coding examples I created a while ago BestelMobiel.net
The site is a fully working front + backend allowing you to take an order at a bar / restaurant which are discovered using the Google Places API.
The Site is fully operational and based on a front- end using a restfull (a la swagger) API.
Most of my domains are registered with a provider in NL, but DNS is handled by AWS Route53.
The main reason for using AWS is scripting, all domains have been scripted and ssl is maintained with certbot.
It's just an generic DevOps example ;-)
PS: I love infrastructure as a code, but I hate too much typing !
