I have a free account in AWS cloud for 1 year for $750$ hours. How to run Mathematica in AWS cloud? And is Mathematica chargeable in AWS cloud?
Install version 11.3 of the player, write your
wolframscript -f script.wl
If you want a GUI check https://github.com/mmatera/iwolfram and run jupyter remotely. On AWS VM run
jupyter-notebook --no-browser --port=7000 then on you local machine
ssh -NfL localhost:7000:localhost:6001 <IP>)
