The insider's guide: 40 must-follow IT ops leaders

Nicole Forsgren, Co-founder, CEO and Chief Scientist, DORA

There has been much ado lately about the DevOps movement—the software development and delivery methodology that is revolutionizing the way that organizations deliver value as software eats the world. And yet so much attention is heaped onto the traditional rock stars of the movement: the developers who change their coding practices to embrace continuous integration, who understand their code needs to be scalable, who embrace failure and fast feedback...

Don't get me wrong. Every movement needs its rock stars out front, but what about the superheroes that are often overlooked, because they do their work so well they remain in the background, largely unnoticed, while keeping our increasingly complex infrastructures up and running? After all, this movement would just be Dev___ without some visionary, pioneering, enterprising ops people, willing to partner and experiment and improve right along with the devs. Without cooperation from both camps, this work would fail. (Sure, there are a handful of places that can do NoOps, but many would argue those are special cases and not applicable to all organizations, such as those with certain regulatory requirements.)

And so I bring you a list of 40 fantastic and influential IT operations professionals to follow online. Sure, there was another list earlier, and the individuals on that list are more than worthy of recognition, but many of them are not in IT operations. In my mind, this distinction is important, because IT operations professionals should be recognized and celebrated for the work they do—not forgotten as we celebrate the rock stars out front.

It may be worth clarifying exactly what IT operations is, and relatedly, what it means to be on this list. IT operations is the work used to keep infrastructure and services up and running—so we're talking about the people who currently manage, or at some point have managed, infrastructures (including public, private, or hybrid clouds), virtualization, containers, likely including configuration management, networking, and several *aaSs. Anyone who has not managed a serious infrastructure, no matter how smart and influential he or she may be, will not show up on this list. I also only included people who are relatively active online (so you can actually follow them), and people who largely tweet about ops, though many of them drift into DevOps at times.

The timing is also perfect, as this week is the 40th anniversary of the USENIX LISA (Large Installation System Administration) Conference, which is being held in Washington, D.C., this year. (@usenix #lisa15).

1. * * * * *

Your own unsung or invisible IT ops person or team. To quote Nathen Harvey, someone who is connected to innumerable IT operations communities, "Unfortunately, it's very difficult to follow the best IT Ops people on twitter....if they were doing less tweeting, they'd be better IT Ops people." So let's not forget the people keeping our own systems up and running. In fact, let's all mark July 29 on our calendars—it's Sysadmin Day! ("Sysadmin" is the old-fashioned term for IT operations, doncha know.) If they aren't on Twitter, go say hi on occasion. Make sure your latest deploy didn't set something on fire.
