Adrian Cockcroft’s article about NoOps at Netflix ignited a controversy that has been smouldering for some months.

What is DevOps?

John Allspaw’s detailed response to Adrian’s article makes a key point: What Adrian described as “NoOps” isn’t really. Operations doesn’t go away. Responsibilities can, and do, shift over time, and as they shift, so do job descriptions. But no matter how you slice it, the same jobs need to be done, and one of those jobs is operations. What Adrian is calling NoOps at Netflix isn’t all that different from Operations at Etsy. At a recent lunch, John noted that back in the dawn of the computer age, there was no distinction between dev and ops. The arrival of minicomputers in the 1970s and PCs in the ’80s broke down the wall between mainframe operators and users, leading to the system and network administrators of the 1980s and ’90s. But somebody has to keep the infrastructure running, including the increasingly important websites.

So infrastructure had to become code. Devops: what it is and why you should be doing it. This could be brogramming.

Devops: what it is and why you should be doing it

It's not devops. Devops is a big deal nowadays, and there’s a variety of ways people describe it and its benefits. Here we’ll move past the fluffy characterization involving developers and operations working together joyously—not to mention the outright wrong characterization of one superrole that does it all—and get to the heart of what devops is really about. DevOps: Adapt or Die. Two bloggers have stimulated a flurry of activity in Sysadmin and DevOps communities recently with their similar conclusions about the ongoing fall of traditional system administration and the arrival of (you guessed it!)

DevOps: Adapt or Die

DevOps. First Chris Siebenmann, a well known blogger and "herder of Unix", wrote in response to Julian Dunn's "Chef, devops, and the death of system administration" (and the subsequent update on his views) His basic argument was that what many people today perceive as sysadmin work is "scutwork" - connecting cables, racking servers, restoring files for people, installing OSes, etc.

His response to the death of system administration was "good". Less boring grunt work and more creative contributions to the organization's prosperity. Then Phil Hollenback hollered back. :) "Like all dinosaurs, we have a choice: adapt or die," agreed Hollenback. The answer is DevOps. Finally, the blogging came full circle when Chris Siebenmann responded to Phil Hollenback. DevOps Zone.

La communauté « DevOps » nous invite à repenser la frontière classique de nos organisation, séparant d’un côté les études, i.e. ceux qui écrivent le code (le “Build”) et de l’autre côté la production, i.e. ceux qui déploient et exploitent ces applications (le “Run”). 2 groupes se retrouvent dans le mouvement DevOps et apportent un peu de fraicheur dans ces réflexions aussi anciennes que les DSIs : les agilistes qui ont levé la « contrainte » côté développement, et sont maintenant capable de « livrer » beaucoup plus souvent du logiciel valorisé par le client…mais regrettent que « la prod ne suive pas »des experts ou des managers de la « prod » des grands du web (Amazon, Facebook, LinkedIn…) partageant leurs retours d’expérience sur leur façon d’envisager cette frontière Au delà des fractures organisationnelles, les préoccupations des études et de la production sont bien distinctes et respectivement louables.

Puppet, Cfengine ou Chef & devops. Pour faire suite à l’article d’introduction sur le mouvement des DevOps, nous pressentons que, dans leur lourde tâche, nos héros vont devoir s’appuyer sur un certain outillage leur permettant de fluidifier la phase de Mise En Production ; qui dit fluidification dit appli déployée plus vite et le business traduit ça par : « la fonctionnalité va arriver bien plus vite au client ».

What Is This Devops Thing, Anyway?

Let's face it - where we are right now sucks. In the IT industry, or perhaps to be more specific, in the software industry, particularly in the web-enabled sphere, there's a tacit assumption that projects will run late, and when they're delivered (if they’re ever delivered), they will underperform, and not deliver well against investment. What is DevOps not? I’ve spent the last two weeks at conferences, and for some reason people keep assuming that I work in operations. Jedi - le blog de Patrick Debois. While working on the Devops Cookbook with my fellow authors Gene Kim,John Willis,Mike Orzen we are gathering a lot of "devops" practices.

For some time we struggled with structuring them in the book. I figured we were missing a mental model to relate the practices/stories to.
