I am using Photon Server on my Windows machine. I am using a free license. Can I create two game servers on one computer so that each have 100 CCU? Sorry, English is not my native language and I can not find the answer.
You can't use the free license in production, it's for development and testing only. You will have to buy one.
Also, each server (being bare-metal or virtual) requires a license. So, you will need to buy another license if you decide to scale horizontally and put another GameServer up.
