Server Operating Systems

A number of well-liked operating systems for servers - such as FreeBSD, Solaris, and Linux  are derived from or are alike to UNIX. UNIX was initially a minicomputer operating system, and as servers regularly replaced conventional minicomputers, UNIX was a logical and capable choice of operating system for the servers. UNIX-based operating systems, many of which are free in both senses, are all the rage.

Server-oriented operating systems be apt to have definite features in common that make them more appropriate for the server situation, such as

  • GUI not accessible or optional,
  • capability to reconfigure and update both hardware and software to various extent without restart,
  • advanced backup facilities to let regular and regular online backups of critical data,
  • transparent data move between different volumes or devices,
  • flexible and advanced networking ability,
  • automation capabilities such as daemons in UNIX and services in Windows, and
  • tight system security, with advanced user, resource, data, and memory guard.

Server-oriented operating systems can in numerous cases interrelate with hardware sensors to notice conditions such as overheating, processor and disk failure, and accordingly alert an operator and/or take remedial actions itself.

Because servers have to supply a limited range of services to perhaps many users while a desktop computer must perform a wide range of functions necessary by its user, the necessities of an operating system for a server are unusual from those of a desktop machine. While it is probable for an operating system to make a machine both offer services and react quickly to the requirements of a user, it is common to use different operating systems on servers and desktop machines. a number of operating systems are supplied in both server and desktop versions with related user interface.

The desktop versions of the Windows and Mac OS X operating systems are deployed on a minority of servers, as are some proprietary mainframe operating systems, for instance z/ OS. The dominant operating systems between servers are UNIX-based and open source kernel distributions.

The increase of the microprocessor-based server was make possible by the development of Unix to run on the x86 microprocessor structural design. The Microsoft Windows family of operating systems in addition runs on x86 hardware, and since Windows NT have been obtainable in versions appropriate for server use.

Though the role of server and desktop operating systems remains separate, developments in the consistency of both hardware and operating systems have unclear the difference between the two classes. nowadays, many desktop and server operating systems share comparable code bases, conflicting mostly in configuration. The shift towards web applications and middleware platforms has as well lessened the  require for expert application servers.
