[I just wanna lead this article out by saying that _I do not have all the
|
|
answers here_. I really wish I did, but I also feel that I shouldn't have to
|
|
have an answer in mind in order to raise a question. Please also keep in mind
|
|
that this is coming from someone who has been working in devops for most of
|
|
their career.](conversation://Cadey/coffee)

## Or: The Social Quandry of Devops
|
|
|
|
Technology is the cornerstone of our society. As a people we have seen the
|
|
catalytic things that technology has enabled us to do. Through technology and
|
|
new and innovative ways of applying it, we can help solve many problems. This
|
|
leads some to envision technology as a panacea, a mythical cure-all that will
|
|
make all our problems go away with the right use of it.
|
|
|
|
This does not extend to social problems. Technical fixes for social problems are
|
|
how we end up with an inadequate mess that can make the problem a lot worse than
|
|
it was before. You've almost certainly been able to see this in action with
|
|
social media (under the belief that allowing people to connect is so morally
|
|
correct that it will bring in a new age of humanity that will be objectively
|
|
good for everyone). The example I want to focus on today is the Devops
|
|
philosophy. Devops is a technical solution (creating a new department) that
|
|
helps work around social problems in workplaces (fundamental differences in
|
|
priorities and end goals), and in the process it doesn't solve either very well.
|
|
|
|
There are a lot of skillset paths that you can end up with in tech, but the two
|
|
biggest ones are development (making the computer do new things) and systems
|
|
administration (making computers keep doing those things). There are many other
|
|
silos in the industry (technical writing, project/product management, etc.), but
|
|
the two main ones are development and systems administration. These two groups
|
|
have vastly different priorities, skillsets, needs and future goals, and as a
|
|
result of this there is very little natural cross-pollenation between the two
|
|
silos. I have seen this evolve into cultural resentment.
|
|
|
|
[Not to say that this phenomenon is exclusive to inter-department ties, I've
|
|
also seen it happen intra-department over choice of programming language.](conversation://Cadey/coffee)
|
|
|
|
As far as the main differences go, development usually sees what could be. What
|
|
new things could exist and what steps you need to take to get people there. This
|
|
usually involves designing and implementing new software. The systems
|
|
administration side of things is more likely to see it as a matter of
|
|
integrating things into an existing whole, and then ensuring that whole is
|
|
reliable and proven so they don't have to worry about it constantly. This causes
|
|
a slower velocity forward and can result in extra process, slow momentum and
|
|
stagnation. These two forces naturally come into conflict because they are
|
|
vastly different things and have vastly different requirements and expectations.
|
|
|
|
Development may want to use a new version of the compiler to support a language
|
|
feature that will eliminate a lot of repetitive boilerplate. The sysadmins may
|
|
not be able to ship that compiler in production build toolstack because of
|
|
conflicting dependencies elsewhere, but they may also not want to ship that
|
|
compiler because of fears over trusting unproven software in production.
|
|
|
|
[This fear sounds really odd at first glance, but this is a paraphrased version
|
|
of a problem I actually encountered in the real world at one of my first big
|
|
tech jobs. This place had some unique tech choices such as making their own fork
|
|
of Ubuntu for "stability reasons", and the process to upgrade tools was a huge
|
|
pain on the sysadmin side because it meant retesting and deploying a lot of
|
|
internal tooling, which took a lot longer than the engineering team had patience
|
|
for. This may not be the best example from a technical standpoint, but things
|
|
don't have to make sense for them to exist.](conversation://Cadey/coffee)
|
|
|
|
This tension builds over a long period of time and can cause problems when the
|
|
sysadmin team is chronically underfunded (due to the idea that they are
|
|
successful when nothing goes wrong, also incurring the problem of success being
|
|
a negative, which can make the sysadmin team look like a money pit when they are
|
|
actually the very thing that is making the money generator generate money). This
|
|
can also lead to avoidable burnout, unwarranted anxiety issues and unneeded
|
|
suffering on both ends of the conflict.
|
|
|
|
So given the unstoppable force of development and the immovable wall of
|
|
sysadmin, an organizational compromise was made. This started out as many things
|
|
with many names, but as the idea rippled throughout people's heads the name
|
|
"devops" ended up sticking. Devops is a hybrid of traditional software
|
|
development and systems administration. On paper this should be great. The silos
|
|
will shrink. People will understand the limits and needs of the others. Managers
|
|
will be able to have more flexible employees.
|
|
|
|
Unfortunately though, a lot of the ideas behind devops and the overall
|
|
philosophy really do require you to radically burn down everything and start
|
|
from scratch. This tends to really not be conducive to engineering timetables
|
|
and overall system stability during the age of turbulence.
|
|
|
|
[What's the problem with burning everything down? Fire cleanses all things and
|
|
purifies away the unworthy!](conversation://Numa/delet)
|
|
|
|
[Not when you're the one being burned!](conversation://Cadey/angy)
|
|
|
|
[Wait, so what actually happens then? Does it just end up being a sysadmin team
|
|
made up out of coders?](conversation://Mara/hmm)
|
|
|
|
[Yeeeeeeeeep.](conversation://Numa/stare)
|
|
|
|
Yeah, in practice this ends up being a "new team" or a reboot of an existing
|
|
team in ways that is suddenly compelling or sexy to executives because a new
|
|
buzzword is on the scene. Realistically, devops did end up getting a proper
|
|
definition at a buzzword conference level (being able to handle development and
|
|
deployment of services from editor to production), but in practice this ends up
|
|
being just some random developers that you tricked into caring about production
|
|
now while also telling them that they're better than the sysadmins.
|
|
|
|
[Two jobs for the price of one!](conversation://Numa/delet)
|
|
|
|
This ends up shafting the sysadmin team even harder because the new fancy devops
|
|
team has things they can talk about as positives for their quarters, so people
|
|
can more easily make a case for promotion. As a sysadmin, your "success" case is
|
|
"bad things didn't happen", which means success can't stand out on reviews.
|
|
Consider "scaled production above the rate of our customer acquistion rate"
|
|
against "set up continuous delivery to ensure velocity on our team, saving 50
|
|
hours of effort per week". Which one of those do you think gets you promoted?
|
|
Which one of those do you think gets headcount for new hires?
|
|
|
|
This has human costs too. At one of my past jobs doing more sysadmin-y things
|
|
(it was marketed as a devops hybrid role, but the "hybrid" part was more of
|
|
"frantically patch up the sinking ship with code" and not traditional software
|
|
development). Sleep is really essential to helping you function properly to do
|
|
your job. During the times when I was pager bitch, there was at least a 1/8
|
|
chance that I would be woken up in the middle of the night to handle a problem.
|
|
I had to change my pager tone 15 times and still get goosebumps hearing those
|
|
old sounds nearly a decade later. This ended up being a huge factor in my
|
|
developing anxiety issues that I still feel today. I ended up getting addicted
|
|
to weed really bad for a few years. I admit that I'm really not the most robust
|
|
person in the world, but these things add up.
|
|
|
|
[I guess "addicted to weed" isn't totally accurate or inaccurate here, it's more
|
|
that I was addicted to the feeling of being high rather than dependence on the
|
|
drug itself. Either way, it was bad and weed was my cope. It also probably
|
|
really didn't help that I was also starting hormone replacement therapy at the
|
|
time, so I was going through second puberty at the time as well. This is the
|
|
kind of human capital cost when dealing with dysfunction like this. I've always
|
|
been kind of afraid to speak up about this.](conversation://Cadey/coffee)
|
|
|
|
However, there are real technical problems that can only really be solved from a
|
|
devops perspective. Tools like Docker would probably never have happened in the
|
|
way they did if the devops philosophy didn't exist.
|
|
|
|
|
|
|
|
In a way, Docker is one of the perfect examples of the devops philosophy. It
|
|
allows developers to have their own custom versions of everything. They can use
|
|
custom compilers that the sysadmins don't have to integrate into everything.
|
|
They can experiment with new toolstacks, languages and build systems without
|
|
worrying about how they integrate into existing processes. And in the process it
|
|
defaults to things that are so hilariously unsafe that you only really realize
|
|
the problems when they own you. It makes it easy to ship around configurations
|
|
for services yes, but it doesn't make supply chain management easy at all.
|
|
|
|
[Wait, what about that? How does that make any sense?](conversation://Mara/wat)
|
|
|
|
Okay, let's consider this basic Dockerfile that builds a Go service. If you
|
|
start from very little knowledge of what's going on, you'd probably end up with
|
|
something like this:
|
|
|
|
```Dockerfile
|
|
FROM golang:1.17
|
|
|
|
WORKDIR /usr/src/app
|
|
|
|
COPY go.mod go.sum ./
|
|
RUN go mod download && go mod verify
|
|
|
|
COPY . .
|
|
RUN go build -v -o /usr/local/bin/app ./...
|
|
|
|
CMD ["app"]
|
|
```
|
|
|
|
This allows you to pin the versions of things like the Go compiler without
|
|
bothering the sysadmin team to make it available, but in the process you also
|
|
don't know what version of the compiler you are actually running. Let's say that
|
|
you have all your Docker images built with CI and that CI has an image cache set
|
|
up (as is the default in many CI systems). On your laptop you may end up getting
|
|
the latest release of Go 1.17 (at the time of writing, this is version 1.17.8),
|
|
but since CI may have seen this before and may have an old version of the `1.17`
|
|
tag cached. This would mean that despite your efforts at making things easy to
|
|
recreate, you've just accidentally put [an ASN.1 parsing
|
|
DoS](https://github.com/golang/go/issues/50165) into production, even though
|
|
your local machine will never have this issue! Not to mention if the image
|
|
you're using has a glibc bug, a DNS parsing bug or any issue with one of the
|
|
packages that makes up the image.
|
|
|
|
[So as a side effect of burning down everything and starting over you don't
|
|
actually get a lot of the advantages that the old system had in spite of the
|
|
dysfunction?](conversation://Mara/hmm)
|
|
|
|
[Yep! Realistically though you can get around this by using exact sha256 hashes
|
|
of the precise Docker image you want, however this isn't the _default_ behavior
|
|
so nobody will really know about it. There are ways to work around this with
|
|
tools like Nix, but that is a topic for another day.](conversation://Cadey/coffee)
|
|
|
|
This is what the devops experience feels like, chaining together tools that
|
|
require careful handling to avoid accidental security flaws in ways that the
|
|
traditional sysadmin team approach fundamentally avoided by design. By
|
|
sidestepping the sysadmin team's stability and process, you learn nothing from
|
|
what they were doing.
|
|
|
|
[This is all of course assuming that at the same time as you go devops, you also
|
|
avow the grandeur of the cloud. Statistics say that these two usually go hand in
|
|
hand as the cloud is sold to executives as good for
|
|
devops.](conversation://Cadey/coffee)
|
|
|
|
As for how to get out of this mess though, I'm not sure. Like I said, this is a
|
|
_social_ problem that is trying to be solved through a _business organizational_
|
|
fix. I am a technical solutions kind of person and as such I'm really not the
|
|
right person to ask about all this. I don't want to propose a solution here.
|
|
I've thought out several ideas, but I got nowhere with them fast.
|
|
|
|
I remember at one of my jobs where I was a devops I ended up also having to be
|
|
the tutor on how fundamental parts of the programming language they are using
|
|
work. This one service that was handling a lot of production load had issues
|
|
where it would just panic and die randomly when a very large customer was trying
|
|
to view a list of things that was two orders of magnitude larger than other
|
|
customers that use that service. I eventually ended up figuring out where the
|
|
issue was but then I had an even harder time explaining what concurrency does at
|
|
a fundamental level and how race conditions can make things crash due to
|
|
undefined behavior. I think it ended up being a 3 line fix too.
|
|
|
|
I guess the thing that would really help with this is education and helping
|
|
people hone their skills as developers. I understand that there's a learning
|
|
curve and not everyone is going to become a programming god overnight, but every
|
|
little bit sets off butterfly effects that will ripple down in other ways. Any
|
|
solution that requires everyone be a programming god isn't viable for anyone,
|
|
including programming gods.
|
|
|
|
[This whole mentorship thing only really works when the company you work for
|
|
doesn't de-facto punish you for mentoring people like that. If you aren't
|
|
careful about how you frame this, doing that could make it difficult for you to
|
|
prove yourself come review time. "Helped other people do their jobs better"
|
|
doesn't really look good for a promotion committee.](conversation://Numa/delet)
|
|
|
|
[Yeah but what are you supposed to do if that kind of mentorship is what really
|
|
helps motivate you as a person and is what you really enjoy doing? I don't
|
|
really see "mentor" as a job title on any postings.](conversation://Mara/hmm)
|
|
|
|
[There's always getting tired of trying to change things from within and then
|
|
writing things out on a publicly visible blog, building up a bunch of articles
|
|
over time. Then you could use that body of work as a way to meme yourself into
|
|
hiring pipelines thanks to people sharing your links on aggegators like the
|
|
orange site. It'd probably help if you also got a reputation as a shitposter,
|
|
usually when people are able to openly joke about something that signals that
|
|
they are pretty damn experienced in it.](conversation://Numa/stare)
|
|
|
|
[You're describing this blog aren't you.](conversation://Cadey/facepalm)
|
|
|
|
Like I said though, this is hard. A lot of the problems are actually structural
|
|
problems in how companies do the science part of computer science. Structural
|
|
problems cannot be solved overnight. These things take time, effort and patience
|
|
to truly figure out and in the process you will fail to invent a light bulb many
|
|
times over. Devops is probably a necessary evil, but I really wish that
|
|
situations weren't toxic enough in the first place to require that evil.
