Are you a developer? Do you like buzzwords? Do you want higher wage? Learn some automation tools and Linux server administration skills, call yourself DevOps expert. You’re welcome.
Jokes aside, DevOps (again, I’m still not sure what that means) is a pretty popular term to throw out these days. As far as I (and Wikipedia) know, the term itself doesn’t refer to a job title, or a description, but it refers to a practice of collaboration and effective communication between IT and software developers.
