Recently I had paid for a Minecraft hosting service called Apex. A hosting service is a company that hosts a Minecraft server on their desktop computer. When you buy a service for a server, you can choose different types. For example, I chose the 2GB server because I am only going to use it for a plain survival world. If you wanted a server for a ton of plugins (plugins change the game to whatever they are supposed to do, for example, this is a plugin that makes it, so only one person has to go to bed instead of everyone who is on the server go to bed.) Then you would probably want to buy the 3GB or the 4GB if you will have a lot of people. The reason I had purchased the server is that I wanted to play on it with some friends on the server instead of a realm that I was playing on because there were about 11 of us, and the realm could only hold ten players, but the server can hold about thirty players.
