I'm thinking more about the following:
1. No sane person is going to pay money to run POV-Ray on Amazon when
they could just run it locally on their own PC for free.
2. I have a vague recollection that attempting to do this contravines
the POV-Ray license.
3. If you *were* going to pay money for a POV-Ray rendering engine, you
wouldn't want to log in, start up a VM, copy all your files onto the
server, configure all of POV-Ray's options, set it running, and check it
three times a day to make sure it hasn't finished. (You'll still be
charged if you don't shut it down as soon as the render is done.)
What you'd *actually* want is a button in POV-Ray that says "submit to
server" and it grabs all the files, INI files, etc., zips them into a
big bundle, uploads it, adds it to the server render queue, and emails
you the result when it's finished or something.
As far as I can tell, it's not possible to do this. Or at least, it's
not possible to use DevPay to do this. You'd have to have an instance
running constantly, and you'd have to pay for it whether there's work to
do or not.
