How do VPS services
A VPS is a virtual machine. A switch adds more ports to a network. There's a virtual switch on the host machine, and each VM is "plugged into" it, getting its own public IP address just like a real machine. Also, the VMs aren't tied to the host and can actually be moved to another host while they're running. The host machine doesn't need a reverse proxy, public IP address, or even an operating system. It runs a hypervisor, which is responsible for creating and running VMs. Each physical server can fit dozens of VPSes, so the service provider has to buy a lot more IP addresses than servers. But to the network, there's no difference between a VPS and a dedicated server.
