Linux Administration

Linux administration skills are essential for managing and maintaining Linux-based servers, which are commonly used in web hosting, cloud computing, and other areas of IT infrastructure.  According to a survey by the Linux Foundation, Linux is the dominant operating system for servers, with a market share of over 90%. Linux administrators need to be familiar with various aspects of Linux system administration, including Linux OS installation and configuration, file system management, user and group management, package management, network configuration, web server administration, database administration, and virtualization. The course is also suitable for individuals who want to pursue a career in DevOps.

The tuition fee for the specialty Linux Administration is 1450 AZN.
