A VPS is a Virtual Private server. Just like you can have a virtual machine on your PC, it is possible to rent server space for a virtual machine from an internet hosting service (IHS). That is called a VPS. You choose a VPS just like you would choose a PC. You decide on an operating system (OS); for running nodes on Partisia Blockchain, you choose Linux-based OS (In this guide, we used Ubuntu). Your VPS is physically capable of running the node if you align it with the recommended machine specs.
