- VPS the Hard Way - Title slide What is a VPS? It stands for Virtual Private Server. Basically you get access to a virtual machine running with dozens of others in a rack in a server room somewhere with fast internet. Since it’s a virtual machine you can run whatever you want. It’s cheap, it’s unsupported, and it’s all yours. Riddle me this! Why? What good is it? Think back to when you first discovered the internet.
