Probably the easiest thing would be to create an AWS template that anyone could then tweak and run to get a fully working environment. Same with Azure as well.
Of course, however, a Node-RED working environment on a public global cloud would likely need to include a full "virtual datacentre" style configuration with a network, edge security, identity management configuration, optimising proxy, ....
Thank you for the reply. I was wondering aloud more than actually looking for an AWS offering.
I was more thinking of the consequences should AWS bring out a AWS branded Node-RED. It would certainly bring more attention to Node-RED but would also suck a lot of air away from the ecosystem around Node-RED.
