Thanks, those are great instructions but I already have set up a Minecraft server on an Amazon Web Services (EC2) server. What I'm trying to figure out is how to leave that server running (so my friends can play anytime) without having to leave my computer running and connected to the AWS EC2 server. I thought that AWS would allow you to have a server running in the cloud by itself (independent of my computer). Is there some trick, setting or tool that I need to do to accomplish this?
