I have website with a domain name pointed to my VPS, do I need a new domain name and a new server or I can use what I already have

Hello everyone,

I have a web application with a domain name that’s pointing to my VPS where the app is deployed.

Inside the app, I have already integrated Jitsi. But, now I would like to self-host it.

Can I do the hosting on the same VPS?
Do I need a new domain name or can I use the app domain name that I already have?

Thank you.

You better do it with separate one like, meet.yourdomain.com
