The cPanel Store offers cPanel & WHM licenses for VPS (Virtual Private Server) and Dedicated (physical) servers. Licenses compatible with VPS are Cloud licenses. Licenses compatible with dedicated servers are Metal licenses.
Answer
There are four different licenses to choose from which dictate on the number of cPanel accounts (users) on a server. A cPanel account is able to manage as many domains or websites as the root user stipulates. Server resources will also be a factor to consider in this regard.
