Rhino Use on Amazon EC2

I have a Rhino/Grasshopper task which is unusually large and thought to carry it out on an EC2 instance.

I am by no means competant in this area however have managed to creat a machine instance and installed Rhino 6 however when I enter my Key it takes me to the licensing website but doesn’t work. Do I need to use Zoo since it’s a server or is this just an impossible task…

Any advice appreciated,. Stay well
