Servers are the center of all modern information technology (IT) departments. They are a complex collection of hardware and software that makes it possible to deliver enterprise-level services to any computer or device across a network. They have been the backbone of the Internet for decades and are used to host websites and web-based applications. The servers require constant management from one or more professionals. Some businesses choose to avoid this problem by using managed dedicated server hosting. This type of hosting includes management as part of the cost of leasing the server. Other businesses perform server management internally with a complete IT staff. Server management includes a few key tasks.
