System Administration
System Administration is the practice of managing, configuring, and maintaining computer systems, servers, and networks to ensure their reliable and secure operation. It involves tasks such as installing software, monitoring performance, troubleshooting issues, implementing security measures, and managing user accounts. System administrators (sysadmins) are responsible for the day-to-day operation of IT infrastructure in organizations.
Developers should learn system administration to gain a deeper understanding of the underlying infrastructure their applications run on, enabling them to build more robust, scalable, and secure software. It is essential for roles like DevOps, site reliability engineering (SRE), or when deploying and managing applications in production environments, such as on-premises servers or cloud platforms. Knowledge of system administration helps in troubleshooting deployment issues, optimizing performance, and ensuring compliance with security best practices.
