Tips to maximize the Dedicated Server that you already have. Choose the right Operating System, this really depends on how complicated and sophisticated the system you want. In addition you should be aware of what the operating system needs and how it will support the website or application that will host on your server.
For example, the website built with ASP.NET then you should choose a web server windows. Other options such as system vulnerability resolution, security fixes and patches and kernel upgrades also need to be considered. In order to ensure the safety and security of servers, you need to know about application updates, security patches and service packs.
Select the bandwidth and connectivity from the server or data center you choose as the host. Usually you get 2 choices for bandwidth and connectivity, 10 Mbits or 100 Mbits with half-duplex and full duplex options. There are more 2 sub options for connectivity, one is fixed bandwidth, if you have 50 Gb of bandwidth allocated to your server then you will be able to exchange Total 50 Gb data in / out from your server, as over limit will incur additional charges or termination of service.
Second is unlimited bandwidth, for example you have 10 M bit full-duplex data assigned to your server, then you can use full capacity without worrying about the amount of bandwidth used. This option is used by sites with streaming or high traffic.
