This is determined by lots of factors, but we have tried to make it simpler to choose.
Your choice should be mainly affected by these factors:
- Server Usage
- Player Count
- Amounts of Plugins or Mods
Server Usage
By server usage, we mean how your server will be used. If you are buying your server to play Survival with a couple of friends then the following applies will be fine, 1GB for 1.8-1.12, 3-4GB for 1.14, and 2GB for 1.15. But if you are going to use it for high-paced pvp battles with crazy enchantments we would recommend a custom server.
Player Count
This is determined by how many players you are expecting to have on your server. The more players you are expecting the more RAM you will need on your server.
Amount of Plugins or Mods
The amount of plugins or mods heavily impacts the amount of RAM your server uses. Mods generally use a lot of RAM, for a modded server we recommend at least 6GB of RAM for your server if you are running a modpack. However, this differs for every modpack.
The amount of RAM plugins used differs a lot for each plugin, however, a general rule of thumb would be 30 plugins per GB of RAM, This can have exceptions if you are using small or big plugins.
We hope this can give you a better view of what plan you should pick, but if you still don't know, don't hesitate to reach out to us.
Please note: The rules of thumb given here are a raw estimate, not a guarantee that it will work.
