Inside the World of System Administrators (and What They do)

Amid the rapid pace of digitalization, computer systems have become the heartbeat of nearly every organization. From small businesses to large enterprises, everyone relies on these systems for seamless operations and communication. But just as a bustling kitchen needs a skilled chef to keep things running smoothly, every organization needs a system administrator (sysadmin) to ensure their technology functions without a hitch.
Sysadmins are the unsung heroes working behind the scenes, meticulously maintaining and managing an organization’s IT infrastructure. They possess a unique blend of technical expertise and problem-solving skills, enabling them to keep servers, networks, and systems up and running. Their role is akin to a chef controlling the kitchen, making sure every component works together flawlessly to deliver a perfect dish—in this case, a perfectly running IT environment. In this blog, we explore the world of system administrators, their key responsibilities, the essential skills they bring to the table, and how you can become one.
What Does a System Administrator do?
System administrators, or sysadmins, are the backbone of an organization’s IT infrastructure. Furthermore, their core responsibilities encompass a wide range of tasks, ensuring that systems operate efficiently and securely. Here are the key duties of a system administrator:
1. Monitor System Performance
System administrators regularly check system logs, CPU usage, memory usage, and network performance to ensure optimal functioning. Moreover, they analyze performance data and trends to identify potential issues before they escalate, maintaining system health and efficiency.
2. Perform Security Audits and Backups
Sysadmins conduct regular security audits to identify vulnerabilities and ensure compliance with security policies. Additionally, they manage daily security backups and periodically test restore processes to ensure data integrity and prevent data loss.
3. User Administration
Managing user accounts, permissions, and access rights, system administrators create, modify, and delete user accounts as needed. Further, this ensures appropriate access to resources and maintains security across the organization’s IT infrastructure.
4. Install and Configure Software and Hardware
IT system administrators set up new hardware, including servers and workstations, and install and configure operating systems, applications, and software updates. Much like a chef ensuring the kitchen has the right ingredients, this ensures all devices and systems are up-to-date and functioning properly.
5. Network Maintenance
Overseeing network components such as routers, switches, and firewalls, a network systems administrator ensures that network file systems are correctly configured and accessible to authorized users. Thus, this maintains reliable and secure connectivity across the organization.

6. Troubleshoot Issues and Outages
A network administrator quickly diagnoses and resolves system issues and outages to minimize downtime. Similar to an orchestra conductor harmonizing a sudden change in the music, they work collaboratively with other IT professionals to address complex problems and ensure continuous system availability.
7. Patching and Updating
Regularly updating firmware and software, IT system administrators protect systems against vulnerabilities. Additionally, they test and deploy patches carefully to minimize disruption to users, ensuring system security and stability.
8. Documentation and Internal Wiki Maintenance
Sysadmins maintain comprehensive documentation of system configurations, procedures, and changes. Further, they use internal wikis to document processes, best practices, and troubleshooting guides, ensuring information is accessible and up-to-date.
9. Database Administration
System administrators also manage database servers and ensure data availability and security. Most importantly, they perform regular backups, recovery, and maintenance tasks to keep databases running smoothly and protect against data loss.
10. Backup and Disaster Recovery Planning
Network administrators develop and implement backup strategies to safeguard critical data. For this reason, creating and maintaining disaster recovery plans ensures quick recovery from data loss events.

Essential Skills of a System Administrator
As a network systems administrator, you need to develop a core set of skills that ensure the computer systems in your organization run smoothly. Here are the top skills you want on your resume:
1. In-depth Knowledge of Operating Systems
Whether it’s Windows, Linux, or Mac, hiring managers look for competency in administering the operating system used in their company. Windows and Linux operating systems are widely embraced and are good systems to start with. Hence, it’s a good idea to check if your industry favors one over others.

Being able to set up and maintain Local Area Networks (LAN) and Wide Area Networks (WAN), in addition to configuring network security features such as firewalls, is often expected of a network admin. This is particularly true at smaller companies, where IT professionals are required to wear many hats.
5. Communication and Interpersonal Skills
In addition to working on a team, system administrators often help other employees who lack the same technical knowledge. Moreover, providing help desk support and other means of assistance requires strong communication skills, making this an essential part of a sysadmin’s successful day-to-day tasks.
6. Problem-Solving and Analytical Thinking
System administrators must be adept at identifying and resolving issues promptly. As a result, analytical thinking helps in diagnosing problems accurately, while strong problem-solving skills ensure that solutions are effective and efficient.
