Install an Atonement: Sins of the Past server through the Control Panel (Servers → Select your server → Game servers → Add Game Server → Atonement: Sins of the Past)
I have had my Minecraft server for me and my girlfriend for a couple of months now via Scalacube hosting, and I have had no issues with the server. Any small problems or setting changes have been easily resolved, and I am overall satisfied with what Scalacube has to offer.
