Management can be a some what deceiving term in the hosting world. Many hosts that offer a managed server mean they might login once a month and run a yum update or windows update, anything over and above that will cost you extra. In most cases an unmanaged server is all you need. Just make sure the host you choose can provide basic support for issues. You might also want to get a server with a control panel such as Cpanel to make basic administration simpler.
