LINUX SYSTEM ADMINISTRATORS FAQ

What is Linux system administration?

Linux is an open-source operating system (OS) that’s easier to secure, update, and maintain than closed-source offerings such as Windows. Because Linux is the most popular OS for servers, Linux system administrators have access to a lot of developer resources.

Here’s a quick overview of the skills you should look for in Linux system administration consultants:

  • Linux system administration
  • Linux distros (e.g., Ubuntu, Unix)
  • IT automation
  • Database technologies (e.g., MySQL, PostgreSQL)
  • Systems languages (e.g., C, C++, Golang)
  • Back-end languages (e.g., Java, PHP)
  • Application technology stacks such as LAMP (Linux, Apache, MySQL, PHP)

Why hire Linux system administrators?

The trick to finding top Linux system administrators is to identify your needs. Are you switching from a cloud-based infrastructure to a physical IT infrastructure for the first time? Do you require an admin familiar with DevOps to implement continuous integration and a continuous delivery pipeline? The cost of your project will depend largely on your scope of work and the specific skills needed to bring your project to life.

How much does it cost to hire a Linux system administrator?

Rates can vary due to many factors, including expertise and experience, location, and market conditions.

  • An experienced Linux system administrator may command higher fees but also work faster, have more specialized areas of expertise, and deliver higher-quality work.
  • A contractor who is still in the process of building a client base may price their Linux system administration services more competitively.

Which one is right for you will depend on the specifics of your project.
