Dr. Reclaimlove or: How I learned to Stop Worrying and Love Devops.

One of the best things (besides the /giphy function in Slack) about getting some time each month to work for Reclaim Hosting is how it has put tasks at my “traditional” full-time IT job into perspective; contrasting my full-time IT environment, which is pretty old fashioned (physical stuff), with an environment that relies heavily on Devops, virtual IT, and cloud administration. Fundamentally, Reclaim is really a model example of how to effectively run a lean startup, manage virtual IT, and stay mostly hands off, and it’s been a good introspective experiment for someone like myself who still grips precariously upon the edge of physical infrastructure and an old-school IT background.

Devops is kind of a contentious term for many “traditional” (read: mostly this means hands-on) IT people, because it represents a massive shift in the way IT work is defined and performed. Since people, especially IT people, are often prone to some degree of change-averseness (guilty) and paranoia (doubly guilty) about their precious hardware racks, “if my infrastructure goes away then my job will go away” is not an entirely unreasonable conclusion to arrive at. We are looking at a fairly unprecedented degree of change in our industry and at blazing speed. Our jobs, though not the same as they were 10 or 15 years ago, did not start becoming substantially different until about 3-4 years ago. Neckbeard the Elder would probably be a high performer at most existing IT generalist jobs in 2013 and 2014…maybe 2015, too. The next generation of IT generalists (and IT generalists will still exist) will not rely upon Neckbeard the Not-Quite-Elder (that’s us) unless we decide, right now, to acknowledge that these changes are happening and that we will perish if we don’t adapt.

So how do we embrace the changes if we’re in traditional IT and not Devops IT? First, we have to acknowledge what Devops actually means…and since the “real” definition of Devops is still up for some discussion, let’s try to define it in the context of traditional IT work:

Devops is a collection of hands-off methodologies designed to reduce the need for physical infrastructure in favor of virtual, managed infrastructure over a hosted medium.

I.E., “use the cloud, and write some scripts.” This is in comparison to the Wikipedia definition of Devops:

DevOps is a software development method that stresses communication, collaboration, integration, automation, and measurement of cooperation between software developers and other information-technology (IT) professionals.”

“Woah woah woah. I’m in IT. I’m not a software developer. I don’t want to have to deal with them.”

This sort of makes it sound like you have to be a software developer in order to be successful in IT, which is not entirely true, but I will stress this: if you want to be successful in IT in 2015+, you need to know something about how to code. Your code doesn’t have to be flashy, and you don’t need to be an expert, but it should be effective and reasonably efficient. And in “code” I recommend learning Bash, Python, or Powershell (if you are in a Windows-heavy environment). I dabble in all three of these languages, and though I am not terribly good, I understand some of the thought processes that developers go through when iterating on their previous code and it helps me “get into the head” of a developer a bit. It’s also a huge opportunity for me, and it can be for you too.

If you’re like me, you are an overworked, overstressed IT admin. I have began to embrace Devops because it gives me an avenue for working less…if I commit to the avenue. Basically, I don’t really want to do any work. I would rather be doing other things that are more fun, but I still need to have a job so I can do those other fun things. Some of those fun things are actually “work” but they’re not really “work” to me but I still get paid to do them? Anyway, I can turn this into a win-win using Devops, and I am actually going to use a very Windows-centric example because it’s the easiest to understand, and because most software developers I know do not use Windows and I am trying to keep something of a line there.

Setting up Active Directory and doing it well is difficult. Setting up AD well using Microsoft Azure is less difficult because I don’t have to worry about unscalable and unstable hardware, vendors, CALs, incredibly obtuse licensing, etc. So what is the opportunity? Setting up AD (in the cloud), integrating it with VMM (in the cloud), and creating a “developer hook” (could be as simple as a batch file run from the requestor’s desktop) so developers in the correct AD groups can request the creation of dev and staging machines (and having those machines created for them) without me having to really touch AD anymore, except also “literally” touch it because that hardware doesn’t exist in my universe. There is nothing for developers to break because if the OS gets completely destroyed somehow they can just request a new virtual machine. Microsoft does a lot of the “devops” work for you in this example because of their integration tools, but you could also Powershell a lot of that work away, intelligently, and then maybe you could even have a real lunch break! By the way, the work you do linking Azure (or AWS, or Google) VPN to your network? That will not be work software developers are going to be doing in the foreseeable future.

I am not some Microsoft fanboi, but this is a simple example of how “thinking” in a Devops way can be hugely beneficial and not so scary at all because it illustrates the need for traditional IT expertise with the development and automation expertise. Few of these opportunities existed even 5 years ago. (OK, so that is a little scary.) If you are reading this blog, you might be thinking “well, he’s preaching to the choir a bit,” but I promise you, based on the things that I have seen and heard, I’m not. If you’re not convinced, look around at what some IT specialists are doing on LinkedIn. IT needs to “get real” on these things soon, and start getting their people trained to think in a way that fosters collaboration and automation.

Instead of being wary of Devops, make it work for you, as we are doing at Reclaim. I’m currently deploying a network and server monitoring solution in the cloud for Reclaim (also a “traditional IT” task) and am creating an opportunity for myself to script or program away the SNMP configuration of hosts I’d like to add to the monitoring solution and making it as close to “zero-touch” as possible. In a more advanced environment, you could do something like this using Chef or Puppet, but for this task in particular, I don’t even really need that solution. I am greatly expanding on my Bash/Shell skills (Dev) while incorporating my security, file transmission, service configuration, and permissions skills (Ops). When the prep work is done, the operator will be able to go through a simple series of conditionals that will copy the SNMP config file over to the machines to be monitored, with no additional input needed from “the IT guy.” This is not scary. Self service is good service. Eventually we may even get to the point of auto-discovery. But that’s TNG, we’re still in Star Trek. 🙂

Jim and Tim have built the powerful engine of Reclaim Hosting using simple, powerful DevOps methodologies and thought processes. In doing so, they can focus on the customer and not let the hardware get in their way, and that is the essence of an effective business. “Think Devops” can be the essence of your IT infrastructure, support organization, and even your sanity, if you learn, as I have, how to embrace these changes and live by this mantra. If you can’t commit yet, just start with “think automation.”

I will post more, in the coming weeks, about the monitoring platform, what we are doing, and I will also post some sample config files either here or on Github that you can port right into your own Linux machines if you’d like to start experimenting with the SNMP daemon. Until then, happy reclaiming!
