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!

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
38. Culture How we can encourage to collaboration and communication?
Automation Is there any repetitive, error prone work to automate?
Lean Focus on removing waste, delivering value in small batches
Measurement Provide feedback to everyone!
Sharing Share everything!
45. Would you made this change?
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.”
- Karl Lagerfeld
