It’s a well-known truth that Linux is one of the most basic operating systems, with low hosting costs and an open-source database. For hosting and other web application uses, the majority of people favour Linux servers.

But what distinguishes Linux from other operating systems is that in 2008, it was a $25 billion ecosystem. Linux has developed to become a computing force since its debut in 1991, powering everything from the New York Stock Exchange to mobile phones, supercomputers, and consumer gadgets.

Linux is an open operating system, which means that it is developed collectively rather than being solely the responsibility of a single business. The Linux economy encourages companies to share research and development costs with their partners and competitors. Individuals and businesses have contributed to its development, resulting in an efficient environment and software innovation.

System administration has become a must-have skill for any company that relies on a sound IT infrastructure. As a result, effective Linux administrators are in short supply. Each organization’s job profile may differ, since the role may take on additional tasks. A senior Linux administrator’s responsibilities include the following:
