Help with deciding on a server

Hello, I am in the early stages of developing a side scroller 2d MMO in Unity with a couple other developers. We are looking to purchase a physical server for the meanwhile to support the game (upto 5 players at a time). Would anyone with experience mind recommending us something or at least tell us what we should be looking for? Thanks

 

Don't know what kind of advice you're exactly looking for but for my game which utilizes new Unity networking, I use dedicated server from this guys serverpronto.com and it works great!
Just be sure to get Ubuntu because I spent like a week trying to run it on CentOS, then switched to ubuntu and it worked out of the box..
Hardware-wise, it really depends on the game, run the server on your PC and check what you need (you can even do that with task manager)..

 

I have not much experience, but I'll also suggest 2 possibilities: Amazon ECM, or self-hosting.
And yep, other people will suggest other things. Just cause there are many possibilities.
