what is devops?
a cross-functional community of practice
dedicated to the study of
building, evolving and operating
rapidly changing resilient systems at scale
you can’t just hire in cultural change

experimentation / improvisation
we create and evolve systems and knowledge
we pursue clearly defined stretch goals
how well do we cultivate knowledge?
safe to fail

retrospective prime directive
“Regardless of what we discover, we understand and truly believe that everyone did the best job they could, given what they knew at the time, their skills and abilities, the resources available, and the situation at hand.”

standards
“For DiRT-style events to be successful, an organization first needs to accept system and process failures as a means of learning… We design tests that require engineers from several groups who might not normally work together to interact with each other. That way, should a real large-scale disaster ever strike, these people will already have strong working relationships”

what is devops?“I’ll tell you EXACTLY what devops means.
Devops means giving a shit about your job enough to not pass the buck. Devops means giving a shit about your job enough to want to learn all the parts and not just your little world.
Developers need to understand infrastructure. Operations people need to understand code. People need to fucking work with each other and not just occupy space next to each other.”
