3. What is DevOps?
DevOps is
..for practitioners, by practitioners.
..a knowledge-based movement.
..decentralized and open for everyone.
..not an product or job title.

4. But why?
• Is DevOps a hype?
• Does DevOps even exist?
• Should we simply do something because everyone else is talking
about it?
DevOps Heaven
Let’s step back and see how we reached here..

5. Waterfall Model
But this Traditional Process:
50%
done?
Not this

6. Please note…
It is a model about
real people working
to build software

2. Business Analysts

5. Testers
6. Operations

9. Agile to the rescue!!

10. Applying Lean Principles to Software Development
A better way of doing the same
End-to-End small
slices of work
