Install a TestPackPleaseIgnore 2 server through the Control Panel (Servers → Select your server → Game servers → Add Game Server → TestPackPleaseIgnore 2)
I've had no problems whatsoever running a server under this platform. It has never lagged (When the right GB is bought for the server) and support has always been quick to answer to any questions I may have had. Would recommend for anyone looking for a stable server with multiple access to different variety of mods and modpacks, or just plain old minecraft.
