Firstly, it is very "weak", and secondly, if you start using the "free" VPS from Amazon, after 2 or 3 months they will start to write off money from your card for overcapacity. So it is better to immediately run node ZOLD on a normal paid server.
You're right. I probably will. Only I want to wait for the wallet for Windows to exit and then launch my ZOLD node. I do not know how to use Linux.
I believe it does work for Windows, but may have some issues. You are welcome to experiment and tell us what doesn't work. Just report any bugs you find to our GitHub repository and we will try to fix them:
