With so many organizations today embracing all the latest technologies out there, having a solid IT infrastructure matters more than ever. Not only is downtime an inconvenience to organizations, but it can easily drive them out of business altogether. According to a study by Gartner, the average cost of IT downtime is $5,600 per minute. This is why organizations need system administrators to keep all their business applications running and up to date.
System Administrator - Overview
A system administrator is responsible for maintaining the entire IT infrastructure of an organization. Their work ranges from maintaining servers to updating software and everything else in between. They are the first point-of-contact for any technical problems that employees face. When no one in an organization faces any issue while doing their job, this means that systems administrators have done their job well.
System Administrator - Roles and Responsibilities
The roles and responsibilities of a system administrator can vary widely from one organization to another. Here are the four types of system administrators based on their roles and responsibilities:
Network administrators manage the entire network infrastructure of an organization. They design and install computer systems, routers, switches, local area networks (LAN), wide area networks (WAN), and intranet systems. They also monitor the systems, provide maintenance and troubleshoot any problems when they arise.
Database administrators (DBA) set up and maintain databases used in an organization. They may also be required to integrate data from an old database into a new one or even create a database from scratch. In large organizations, there are specialized DBAs who are only responsible for managing databases. In smaller organizations, the roles of DBAs and server administrators can overlap.
Server or web administrators specialize in maintaining servers, web services and operating systems of the servers. They monitor the speed of the internet to make sure that everything runs smoothly. They also analyze a website’s traffic patterns and implement changes based on user feedback.
Security Systems Administrators
Security systems administrators monitor and maintain the security systems of an organization. They develop organizational security procedures and also run regular data checkups - setting up, deleting and maintaining user accounts.
In large organizations, all these roles may all be separate positions within one department. In smaller organizations, they may be shared by a few system administrators, or even one single person.
System Administrator - Skills
Since maintaining an entire IT infrastructure is not an easy feat, system administrators need to have a mixture of hard and soft skills. Here are a few skills that companies look for in system administrators.
- Knowledge of different operating systems (Microsoft, Unix, Linux, etc.)
- Hardware knowledge
- Attention to detail
- Problem solving mindset
- Critical thinking
The most important skill for a system administrator is the ability to solve problems under pressure. Since every minute is critical for the success of a business, a system administrator should be able to quickly diagnose what is wrong and how best to fix it.
System Administrator - Educational Qualification
The basic requirement for a system administrator is a bachelor’s degree in Computer Science, IT, IT systems management, or any other related field. However, you can also opt for certification programs with a core emphasis on hardware, computer networks, and system administration. An updated professional certification is the quickest tool that employers can use to check your skills.
