What is the difference between DevOps engineer Vs DevOps consultant Vs DevOps architect?

Considering Role wise & Salary wise & Seniority wise & job demand wise, etc.

An architect is somebody who thinks and creates designs.

A consultant is somebody who gets hired for things like "Teach us how to do so and so", or to answer questions like "What's your opinion about this design?".

An engineer is the one who is objective oriented and pragmatic, something along the lines like "How can I get that design (created by the architect, and validated by the consultant) implemented and make it work"?.

Their salaries may vary (there are cheap and expensive ones), same for seniority (there are juniors and seniors, while everybody starts as junior, not all of them ever make it to senior). And job demand is pretty variable (by region, over time, economical factors, depending on hypes, etc).

BTW, it doesn't really matter what the actual "subject" is, it could be "IT", it could be "Road Construction", or it could even be "DevOps" ...

PS: What's in a name (or jobtitle), how about a DevOps BA, as shown in this post ...

    @Newtopian merci for the comment, though I'm not sure what "Nitpicking" means (and I don't have a dictionary handy ...). About Object Oriented: that's like in OOP, aka Object Oriented Programming, whereas the "Object" is to get the "Programming" done ... (the definition I was ever given by an old school mainframe programmer ...). – Pierre.Vriens Aug 31 '17 at 14:54

    nitpicking --> "pinailler", "Trébucher sur les fleurs du tapis", "Chercher des poux" etc as in I was the one doing the nitpicking here pointing this out. I see now what you meant with Object Oriented and it makes perfect sense. Might I suggest Objective Oriented as to disambiguate from the programming paradigm OOP towards which my first thoughts went to when I read your post. – Newtopian Aug 31 '17 at 15:03

    Hey @Newtopian : please go ahead and suggest an edit to my post (I'll probably approve it) ... PS, I found my dictionary ... you mean "muggezifterij" (your turn to go find a Dutch dictionary if you want to QA-test my translation ...) – Pierre.Vriens Aug 31 '17 at 15:06

    Merci @Newtopian ... also for the suggested edit ... as you may have noticed: I just issued the final (only in this case ...) approval of it. – Pierre.Vriens Aug 31 '17 at 15:20

You might want to check the accepted answer to this question: Why shouldn't I try to hire a 'DevOps Engineer'?

Or maybe the article "7 DevOps roles you need to succeed", which includes these (critical?) roles:

  1. DevOps evangelist
  2. Release manager
  3. Automation architect
  4. Software developer/tester
  5. Experience assurance (XA) professional
  6. Security engineer
  7. Utility technology player
  • Hey Mr. "J" ... the article you linked to doesn't mention a role like "BA for DevOps", any idea why not? And/or what such "BA for DevOps" actually means? – Pierre.Vriens Aug 31 '17 at 14:28
  • Links are helpful, but it's encouraged that you provide context and quote relevant sections, plus add your own commentary. See: Your answer is in another castle: when is an answer not an answer? for the current guidelines for answering with a link. – Aurora0001 Aug 31 '17 at 15:05
  • Hey Mr. "J" (again) ... please QA-review the edit I applied to your post, trying to address the comment (and possibly downvote?) from @Aurora0001 ... feel free to rollback if you don't like my edit at all ... PS: where is the DevOps "Manager" in that article (= the one who doesn't have to do anything, if everybody else does his/her job, except from approving budgets and things like that)? – Pierre.Vriens Aug 31 '17 at 15:16
  • Hi @Pierre.Vriens - thanks for editing. PM might be quite unrelated to DevOps context. DevOps BA is sth I would like to establish. Give me 15 minutes to add two relevant links here. In short, BA (Business Analyst) in scrum terms means product owner, e.g. CI/CD infrastructure is an internal organizational product. – Peter Aug 31 '17 at 17:33
