If your plan is to just hire software engineers, you're going to have confused applicants, if your plan is to hire sysadmins, they probably will have a different skillset than you need. Most real companies hire DevOps engineers because that's the way to get the people with the skillsets you need.
Being so purist about this sounds to me like useless debate, but maybe you have better suggestions.
At my current place we stopped hiring DevOps and started hiring SREs + software engineers for specific internal teams, but for a few years there between 2010-2020, good luck getting people with DevOps skills without actually advertising DevOps roles.
What's DevOps skills in your opinion?
If you could write complex shell or perl scripts, and you knew how to dig into performance metrics on the fly, you were a god. (Yeah, capturing and displaying system metrics was in its infancy, and most shops simply didn't know how to do it)
While some systems were built to be "horizontally scalable", you were lucky if you worked with systems that weren't SPOFs. You were happy with redundancy via active/passive failover (and that was probably a manual affair). Maybe if you were really lucky, you worked for a SaaS that served a monolithic website via a fleet of webservers behind an F5 loadbalancer. "Wooooah!". But you still set up those F5 VIPs and pools manually.
The modern systems engineer rarely has to do anything like this, even though the underlying technology is similar. These days everything you care about is in git, and is mostly testable on git push. Modern companies, including tiny 4-person SaaS startups, can have infrastructure-as-code, configuration-as-code, packer configs, dockerfiles, container orchestration, CI/CD, metrics collection, USE/RED metric graphs for every system with alerting, pager, incident handling runbooks...
At some point over the last 25 years, the term Systems Engineer could mean that you're an expert in the old ways or the new ways. When you advertised for a DevOps engineer, it left no doubt that you were looking for the modern variety and expected that experience and skillset.
On another note, how amazing it is to define our systems so we can more systematically iterate on them and improve. I love it when developers get integrated into the process as well.
The general consensus where i work is that everyone does DevOps, you develop the app, you make sure you deliver the app, if there's any issues you debug. You ain't done until your ticket is in production, and you can't point to other to solve it for you, only help you.
Where does the DevOps engineer fit in there?
Improving pipelines. Dealing with downtime on the CI. Improving performance of the CDN. Writing better tooling for the devs to deliver value even faster.
I asked for alternative suggestions and offered what we use. If you have suggestions of alternative titles you've successfully used to hire without slowing things down I'm all ears.
> What's DevOps skills in your opinion?
The most important skill is knowing to not fall for the bait that is this question so that you can actually work.
I think the only reason to advertise for it as a role, is when your tooling is too complex and you've given up looking for Software Engineers that could do it on the side. Which is fair enough, I guess, though providing a Golden Path nowadays is probably more popularly done by hiring Platform Engineers.
The analogy with agile is pretty good here. Sure you could have an Agile Engineer, that works primarily with making sure the agile process is actually used and help facilitating that. Normally that would not be a position itself though, especially not an engineering one.
Never had someone tell me I dont understand my own conclusion to my own article before. Thats a first.
If you are out there interviewing for a DevOps job and you hear things like this: run. Every meeting you have with this person will be a living hell. Endless debates on semantics and definitions while your project is due today.
Those who can manage to surpass that though can get great productivity from it though.
DevOps is great, but it's not a title. It's beautifully summarized in "The DevOps Handbook" and it's fictional counterpart "The Pheonix Project". It's about culture.
Some people might feel different and want to re-evaluate due to so many company adapting it in a similar vein many companies want to adapt agile. But make no mistake, you can't define it then, since then the context of the company defines the word. Thus sadly the word is slowly loosing its meaning.
This is likely due to lots of management people wanting to adapt the buzzword without understanding it. This since it has have had such a great success in many companies that actually know what it is, have taken the DevOps culture to heart and implemented processes in line with it.
