Linux Server administration is essential for many companies, yet the cost of a full-time Linux System Administrator can be prohibitive for small to medium enterprises. Paying high charges for tasks like installations and upgrades is common, and the unavailability of administrators when needed is a challenge. Proactive system monitoring is crucial for uptime, but not all companies have dedicated IT staff for these tasks. Businesses prefer to allocate IT professionals to more productive work like application development.
Linux, conceived by Linus Torvalds and collaborators, debuted on September 17, 1991. Its key strength lies in being open-source, allowing programmers to tailor their own OS using the Linux Kernel. This flexibility fosters innovation and customization in operating system design.
Linux is a dominant force in computing, powering web servers, mobile devices, PCs, supercomputers, and cloud servers. The role of a Linux systems administrator involves overseeing system operations, including maintenance, user management, backups, and utilizing command-line tools.
