Sysadmin 101: Automation

This is the second in a series of articles on systems administrator fundamentals. These days, DevOps has made even the job title "systems administrator" seem a bit archaic, much like the "systems analyst" title it replaced. These DevOps positions are rather different from sysadmin jobs in the past. They have a much larger emphasis on software development far beyond basic shell scripting, and as a result, they often are filled by people with software development backgrounds without much prior sysadmin experience. In the past, a sysadmin would enter the role at a junior level and be mentored by a senior sysadmin on the team, but in many cases currently, companies go quite a while with cloud outsourcing before their first DevOps hire. As a result, the DevOps engineer might be thrust into the role at a junior level with no mentor around apart from search engines and Stack Overflow posts.
