DevOps was a reasonable idea, but it rarely actually manifested. If a company had an actual "DevOps group" separate from the developers, by definition they weren't doing DevOps.
Conversely, there are lots of folks who love ops type problems and are not well suited to building apps. So, it makes sense to put them on separate teams where they can each do the thing that they're best at, rather than fumble through the parts of the jobs they hate. But yes, at this point it's not really DevOps anymore, it's just ops.
Some places do have really well built out platforms where logging, instrumentation, databases, deployment methodologies, IaC, etc have well-built happy paths that exclude a bunch of accidental complexity.
I think a lot of other places are either too small or grow too quickly with the wrong set of values and admit too much into their "platform" which had very little design to begin with.
Having the maintenance/ops requirements directly feed back into the design and engineering of the product is genuinely powerful. Especially for certain kinds of products, if executed with discipline you can get really good engineering reaction time with no degradation of quality, and often with much cheaper infra costs.
The problem is what you said though. People with both skillsets are rare, and combining them is legitimately a third skill on its own. And even "both" skillsets is a simplification once you start accounting for data, security, compliance, large scaling DB work etc.
It was mostly a dead end for these reasons but it was worth exploring for its potential. And some genuinely good engineering techniques went mainstream out of it, not a total waste.
I've found that "ops" has become far too overabstracted and jargony. Their moat is endless "certifications". Their "experts" are the dogmatic personality types who try everything in their power to prevent their feet from ever touching the ground like it's lava. They lack the kind of dev or sysadmin experience where you have to stand under your own constructions like a Roman engineer.
Any formerly-known-as "full stack" dev who kept at it for the last decade and a half would run circles around anyone in ops. That's every senior dev working right now who doesn't like to manage people.
It used to be that the ones who went SRE just wanted a pay bump for a bullshit job of relatively light coding puzzles and parroting stuff in meetings, but I guess that well has dried up with "AI".
But if you have the budget and connections to hire a department of people with these skills and experience, and a problem interesting enough to keep them engaged in the day to day building, and a leader capable and charismatic enough to align them all into the business's goals... you should do that.
It turns out about as well as if you set the Ops team to shipping features.
Eg I’ve seen more than one full stack dev team build a synchronous RPC-over-message-bus framework because they can’t figure out how to make HTTP or actual RPC calls reliable. It is hands down the most poorly and overengineered thing I have ever seen on a service that takes single digit qps.
The ops teams fight that shit tooth and nail because if it blows up, they’re the ones who get called. And it is 100% too late to fix it by then. Ripping it out will take months, and the dev team will say they’ll do it, but they never will because the VP is leaning on them about some feature.
You either say no early, or you are forever on the hook for whatever abomination the intern has cooked up.
You’re so right. This is the key, whether a team is doing devops or not.
One of my major contributions when I took on a CTO role was getting dev, ops, and support teams to talk about the pain points. There were so many easy wins to make things run better because the teams didn’t understand the difficulties the other teams were going through.
Some of the best meetings I setup were with head of the CX (Customer Experience).
The reason is SREs typically work on Infra/Product, but rarely see the pain customers endure outside of major incidents.
Where it worked well is the "devops" or sre/sysadmin would sit in the same team and take away the rough edges of the infra.
conversly they would also keep an eye on the web people and see what they are doing and why, learning the tooling they use and try and rationalise it so they don't install 50 messaging queues.
Exactly this was the idea: persons in a DevOps role have skills in both areas, i.e. are very wide skill set, so that one can assign them to very diverse tasks for more flexibility. Additionally, these persons can implement synergies to make things more efficient in areas that intersect both development and operation.
In the early days of devops it was primarily focused on supporting developer productivity (CI/CD) but quickly morphed into sysadmin once cloud computing took off.
Your comparison might work better for a dev with no testing experience. Write the code and throw it over the wall. But I fail to see how an application engineer should need to worry about the intricacies of, say, setting up virtual private gateways.
That’s not to say you can’t have operations experts or ops-only roles. You can. But if the developers don’t participate in operations at all, they are doing themselves and the business a disservice.
It’s exactly like having a chef who doesn’t taste food, or a car mechanic that doesn’t drive. Some savants exist who can do good work even then, but they’re vanishingly rare.
To my understanding, this _is_ DevOps in the original sense of the word, and the version where they are a separate team is an offshoot bastardization.
At my last job, it was somewhere in-between where we had DevOps specialists who were regular software engineers who allocated the bulk of their time to building / running infra via Real Code (Pulumi vs. TF, minimal YAML wrangling etc) and built paths for app devs to self-service as much as they could. That, I felt, was a really excellent setup.
