My talk at AgileNOIDA

1. DevOps: Process, Tool or
Mindset?
Tathagat Varma
Founder & CEO, ThoughtLeadership

2. 2014:
Founded “Thought
Leadership”
2015:
Wrote “Agile Product
Development”
(2016):
Agile Cultures

3. The journey so far… Developers built and
ran the systems
Developers
built the
systems
Operators
ran the
systems
Developers built
the systems
Testers tested the
systems
Sys Admin
managed the
systems
Operators ran the
systems
???

4. We “created” silos...
Developers Testers OperaTons
Code SoUware Service

5. …and the problems ensued!
SoUware was (almost) always late
If/when delivered, deployment was a major risk
When deployed, soUware would invariably underperform
Changes were episodic, and way too risky
When problems were found, “Us Vs They” blame game
Time/cost to find issues was huge, to fix is even more
…

6. …and then “Agile” happened in
Development teams!
But some silos conTnued…
Developers OperaTons

7. The Wall of Confusion: One Company,
Two Mindsets…

hai?”

9. Modern-day Business Challenges
• Deployments @scale Faster
• Systems @scale Be_er
• Performance @scale Cheaper

10. So, what is Devops?
The term was coined by Patrick Debois in 2009. He wanted to
extend Agile principles into sys admin and ops.
Enable collaboraTon between all teams involved in building,
shipping and managing a feature
Developers don’t just focus on funcTonality. Performance and
Reliability are just as important.
OperaTons don’t get involved only towards the end, but
throughout the development lifecycle.
Tools might help, especially for large deployment, but culture
comes tops.

11. DevOps for ExecuTves
It's a way to smooth the process of developing and releasing code – how to make it easier.
Hiring DevOps engineers helps you streamline the process and make it easier for developers to
work on the code they care about.
It’s not a posiTon, it’s a collabora5on mindset between individuals that want clean, quality
code development that works as it should. TIP, or Test in ProducTon is an agile property of quick
consistent release. Also keep CAMS in mind: customer service, automaTon, measurement, and
sharing.
A process where development and produc5on are integrated with a lot of things in producTon
specified by developers and vice versa. It's a real-Tme feedback loop.
What good teams have been doing for a long Tme. DevOps uses communica5on to solve
problems.

22. From Mindset to Tools!
Mindset
Culture
Process
Methods
Tools
The crux!!!

23. Conclusions
Just wriTng good code is not enough anymore!
Infrastructure is the new code!
System performance can’t be an aUerthought
Despite a perfect code, “perfect storms” happen
DevOps tools can help if there is a mature process
DevOps process can help only if there is right mindset
