multiple servers on one pc

I would like a lot of help, I currently serve two different clinics remotely I have a server installed on each machine in my house, but I would like to know if I can serve these two clients with just one server, or if I can install more than one server per PC .
I currently use linux mint


You can run multiple instances at once. I would recommend using docker and docker-compose to make this as easy as possible. The only thing you need to be aware of is you will need to run them on different ports ie: 1 instance on 4242, 1 instance 4243 etc…

To install Docker on Ubuntu & Mint - To install Docker-compose

And a great resource for how to run orthanc in Docker and here is an example of running multiple instances
