This is a zero content, generic fluff piece. It could be about any methodology! For example, replace devops with agile (or any other methodology) and devops-engineer with scrum-master. This is an insult to the reader.
I stopped reading at the point that an article trying to tell us how to effectively implement DevOps started talking about “DevOps Engineers”. I also got that little bit closer to getting “DevOps isn’t a job title” stickers made.
