[TriLUG] Dev/Ops research

Wed Mar 27 20:31:39 EDT 2019

Ron,

I am in a DevOps transformation team. We work with software delivery teams
in our company to help them transform to DevOps methods and practices. I
also coach and train DevOps, and I hold an ICAgile
<https://www.icagile.com/> DevOps certification
<https://www.icagile.com/Learning-Roadmap/DevOps>. As the other folks have
said on this thread, there are about as many different definitions as there
are practitioners. It started as a way to fight night and weekend work for
development and operations teams, and I still consider that the "holy
grail" of DevOps - everything safely completed between 9-5 M-F.

I recommend reading *The Phoenix Project*
<https://itrevolution.com/book/the-phoenix-project/>, *The DevOps Handbook*
<https://itrevolution.com/book/the-devops-handbook/> and *Accelerate*
<https://itrevolution.com/book/accelerate/> by the folks at the DORA
<https://www.devops-research.com/> - Gene Kim <http://www.realgenekim.me/>, Jez
Humble <https://itrevolution.com/faculty/jaz-humble/>, Nicole Forsgen
<https://nicolefv.com/>, et al. Their approach to DevOps could be summed up
as "the application of Agile-Lean methodologies to entire value streams."
Whereas Agile is usually found within software development teams,
"Agile-Lean DevOps" should happen at every step from customer request to
customer use in production. The "Three Ways
<https://itrevolution.com/the-three-ways-principles-underpinning-devops/>"
- Flow, Continuous Feedback, and Experimentation - echo Lean Development
principles, especially identifying and removing bottlenecks and waste by
visualizing flows and limiting work in progress (WIP).

All of that nonsense up there ^^^, in reality, looks like lots of
automation, collaborations between developers and ops/infosec/QA, and
"shifting left" so that testing/security/configuration is handled as code
by developers using CI/CD principles. Look for teams that keep test cases
and configuration under source control. Look for commits to trigger builds,
tests, packaging so that every commit potentially creates a tested,
deployable release. Look for ops teams that relish deploying to production
because it's so damned easy and low risk. That's DevOps in practice. Oh,
and nobody ever works nights or weekends.
