Install a MRPG - Massive Role Play Game server through the Control Panel (Servers → Select your server → Game servers → Add Game Server → MRPG - Massive Role Play Game)
I've been using Scalacube for a month to host a Minecraft server for my Twitch community. So far I've had no stability issues or lag, everything has been running smoothly! I'm very new to hosting servers so I've been confused a couple times but all support tickets I've sent when I got lost were answered in a timely manner as well. I recommend using them for your server :)
