The document then discusses the history of approaches like Agile, Scrum, and Continuous Integration that influenced DevOps.

Hello I’m mr. DevOps!
• No it’s not a single person!
• No it’s not a role!
• No it’s not a title!

7. 7 14/10/14
DevOps-team!
No it’s not a “yet-another-new-team” in the company!

8. 8 14/10/14
Automated testing IS NOT DevOps
It’s called Continuous Integration!
Automated infrastructure IS NOT DevOps
It’s called Infrastructure As Code!
Automated deployment IS NOT DevOps
It’s called Continuous Delivery & Deployment!

2000- From product to service shift

21. When consumer buys a car (product) he
wants that it has all possible features, but…
…when he uses taxi (service) it doesn’t
matter what features it has,
just that it takes him from A to B

24. New requirements for developers and operations
• Fast, tested, fail safe, small changes continuously
deployed to production
• Measure, share visibility and provide feedback of
users to business, continuously.
• Small experiments, test assumptions, fail fast and
learn!
• Capability to pivot rapidly and often

And that’s what it’s all about

26. Three ways
System thinking
Culture Ops
Feedback
(customer)
Dev
(business)
By Gene Kim

27. Think your whole development process as a
system where single change is the item.
How can you make the process
better, faster, smooth and error safe?
-System thinking

28. If you don’t measure, you cannot improve.
It’s like driving car eyes blinded!
-Feedback

29. Understanding that repetition and
practice is the prerequisite to mastery!
-Culture of continuous experimenting and learning

It’s not free, but worth it in long term.

46. “Reinvent new combinations of what you
already own. Improvise. Become more
creative. Not because you have to, but
because you want to. Evolution is the
secret for the next step.”
