A system administrator, or sysadmin, is a person who is responsible for the upkeep, configuration, and reliable operation of computer systems; especially multi-user computers, such as servers.

The system administrator seeks to ensure that the uptime, performance, resources, and security of the computers he or she manages meet the needs of the users, without exceeding the budget.

To meet these needs, a system administrator may acquire, install, or upgrade computer components and software; automate routine tasks; write computer programs; troubleshoot; train and/or supervise staff; and provide technical support.

Related fields[edit]

Many organizations staff other jobs related to system administration. In a larger company, these may all be separate positions within a computer support or Information Services (IS) department. In a smaller group they may be shared by a few sysadmins, or even a single person.

In some organizations, a person may begin as a member of technical support staff or a computer operator, then gain experience on the job to be promoted to a sysadmin position.

Training[edit]

Unlike many other professions, there is no single path to becoming a system administrator. Many system administrators have a degree in a related field: computer science, information technology, computer engineering, information systems, or even a trade school program. On top of this, nowadays some companies require an IT certification. Other schools have offshoots of their Computer Science program specifically for system administration.

Some schools have started offering undergraduate degrees in System Administration. The first, Rochester Institute of Technology[1] started in 1992. Others such as Rensselaer Polytechnic Institute, University of New Hampshire,[2] Marist College, and Drexel University have more recently offered degrees in Information Technology. Symbiosis Institute of Computer Studies and Research (SICSR) in Pune, India offers Masters degree in Computers Applications with a specialization in System Administration. The University of South Carolina[1] offers an Integrated Information Technology B.S. degree specializing in Microsoft product support.

As of 2011, only five U.S. universities, Rochester Institute of Technology,[3] Tufts, Michigan Tech, and Florida State University [4] have graduate programs in system administration.[citation needed] In Norway, there is a special English-taught MSc program organized by Oslo University College [5] in cooperation with Oslo University, named "Masters programme in Network and System Administration." There is also a "BSc in Network and System Administration" [6] offered by Gjøvik University College. University of Amsterdam (UvA) offers a similar program in cooperation with Hogeschool van Amsterdam (HvA) named "Master System and Network Engineering". In Israel, the IDF's ntmm course in considered a prominent way to train System administrators.[7] However, many other schools offer related graduate degrees in fields such as network systems and computer security.

One of the primary difficulties with teaching system administration as a formal university discipline, is that the industry and technology changes much faster than the typical textbook and coursework certification process. By the time a new textbook has spent years working through approvals and committees, the specific technology for which it is written may have changed significantly or become obsolete.

In addition, because of the practical nature of system administration and the easy availability of open-source server software, many system administrators enter the field self-taught. Some learning institutions are reluctant to, what is in effect, teach hacking to undergraduate level students[citation needed].

Generally, a prospective will be required to have some experience with the computer system he or she is expected to manage. In some cases, candidates are expected to possess industry certifications such as the Microsoft MCSA, MCSE, MCITP, Red Hat RHCE, Novell CNA, CNE, Cisco CCNA or CompTIA's A+ or Network+, Sun Certified SCNA, Linux Professional Institute among others.

Sometimes, almost exclusively in smaller sites, the role of system administrator may be given to a skilled user in addition to or in replacement of his or her duties. For instance, it is not unusual for a mathematics or computing teacher to serve as the system administrator of a secondary school[citation needed].

Skills[edit]

Some of this section is from the Occupational Outlook Handbook, 2010-11 Edition, which is in the public domain as a work of the United States Government. The subject matter of system administration includes computer systems and the ways people use them in an organization. This entails a knowledge of operating systems and applications, as well as hardware and software troubleshooting, but also knowledge of the purposes for which people in the organization use the computers.

Perhaps the most important skill for a system administrator is problem solving—frequently under various sorts of constraints and stress. The sysadmin is on call when a computer system goes down or malfunctions, and must be able to quickly and correctly diagnose what is wrong and how best to fix it. They may also need to have team work and communication skills; as well as being able to install and configure hardware and software.

System administrators are not software engineers or developers. It is not usually within their duties to design or write new application software. However, sysadmins must understand the behavior of software in order to deploy it and to troubleshoot problems, and generally know several programming languages used for scripting or automation of routine tasks.

Particularly when dealing with Internet-facing or business-critical systems, a sysadmin must have a strong grasp of computer security. This includes not merely deploying software patches, but also preventing break-ins and other security problems with preventive measures. In some organizations, computer security administration is a separate role responsible for overall security and the upkeep of firewalls and intrusion detection systems, but all sysadmins are generally responsible for the security of computer systems.

Duties[edit]

A system administrator's responsibilities might include:

In larger organizations, some of the tasks above may be divided among different system administrators or members of different organizational groups. For example, a dedicated individual(s) may apply all system upgrades, a Quality Assurance (QA) team may perform testing and validation, and one or more technical writers may be responsible for all technical documentation written for a company. System administrators, in larger organizations, tend not to be systems architects, system engineers, or system designers.

In smaller organizations, the system administrator might also act as technical support, Database Administrator, Network Administrator, Storage (SAN) Administrator or application analyst.
