This article explains what a Virtual Private Server (VPS) is to a user. Running the Gala Node software requires a stable internet connection and enough computing resources to run the software. Rather than buying a computer and dedicating it to running the Gala Node software, they can rent a VPS as a computer. A good VPS provider can provide up to 100% guaranteed uptime. 

A VPS is a virtual computer that people can rent for a fixed monthly price.  A VPS provider splits a large, powerful computer into smaller, less powerful virtual computers. People can customize their computer based on the needs of the node network.  

It is often more cost effective to rent a VPS, rather than spending the money to buy a dedicated machine for each machine running the Gala Node software. Pricing can vary based on provider, but a reputable provider can offer much better uptime than hosting at home. Many providers guarantee 99% uptime, some even as much as 100% uptime. This is because there’s a large infrastructure in place to keep the servers running, even through a power outage. Some node license owners may have bad internet connection or inconsistent power, so using a VPS may be the best option.
