Hello .
I saw your project by accident and after reading it, I decided to register on this site to help you solve the problem.
What you want to test is the relevance and feasibility between openvpn and Alibaba Cloud and the business.
Very coincidentally, my experience can almost help you.
I am an experienced IT practitioner myself, and often organize and use cloud servers myself.
At the same time I am a gamer and have spent some time using my own vps multinational games.
I find the cloud server myself, build software myself, and manage it myself.
Actually, I still use the Openvpn server I built recently.
The friends I meet in life usually rate me as modest, enthusiastic and very professional.
I think I know exactly what you want to find.
