This document discusses ScrumOps, which combines Scrum and DevOps practices. It defines DevOps as enabling organizations to quickly and safely develop, test, deploy, and operate software through collaboration between development and operations teams. Key DevOps principles discussed include continuous integration, delivery, feedback, and improvement. The document recommends practices like infrastructure as code, automation, and measurement to establish a collaborative culture between Dev and Ops.

Malaysia, Singapore, Indonesia, Hong Kong, Saudi Arabia, Dubai and Philippines.
Strength – Knowledge about Scrum, Kanban and Scaling Agile (LeSS, Nexus,
Spotify). Hands-on TDD, BDD, CI/CD, DevOps, Emergent Design and Agile
Testing Automation
Weakness – Don’t go by book and don’t like prescriptive frameworks

3. DevOps
Enables organizations to create a safe system of work, where
teams are able to quickly and independently develop, test, and
deploy code and value quickly, safely, securely, and reliably to
customers.
By adding the expertise of Dev, QA, IT Operations and Infosec
into delivery teams and automated self-service tools and
platforms, teams are able to use that expertise in their daily
work without being dependent on other teams.
Allows organizations to maximize developer productivity, enable
organizational learning, create high employee satisfaction, and
win in the marketplace.

Tools
Process
People

6. DevOps History
Patrick Debois and Andrew Shcafer presented paper in Agile
Conference, Canada in 2008. They talked about applicability of
Agile Principles in Infrastructure.
John Allspaw and Paul Hammond gave the seminal “10 deploys
per Day: Dev and Ops cooperation at Flickr during Velocity
conference in 2009
Patrick Debois got inspired by above idea and created the first
DevOpsDays in Ghent, Belgium in 2009. There the term
“DevOps” was coined.

7. Dev or Ops?
Software deployed but server showing all red (CPU, RAM etc.)
Software deployed but email not working
There is issue with the build. Code is not building.
Software deployed in QA but testers not able to login
Software deployed but HTTPS not working
Breaking in production but unable to reproduce on my
system

8. Looks familiar?
I spent 70%
time in waiting
I don’t have
spare capacity
Test System are
not realistic

How to
escalate?
I am constantly
fighting fires
What is IT
doing?

10. So what is DevOps?
Source – Wikipedia. Venn diagram showing DevOps as the intersection of development (software
engineering), operations and quality assurance (QA)
NO. This is not DevOps

11. So what is DevOps?
Methods for Improving
Communication CollaborationIntegration
Between DEV and OPS

12. Collaboration Benefits

13. Processes Vs Values
Business Failure
Useless Stuff
Business Success
Technical Debts
Technical Practices
Build it Right
Build the Right Product

14. Collective Ownership of Delivery
Engineering Practices like TDD, BDD, Pair Programming,
CI/CD, Agile Testing and DevOps etc.

15. DevOps and Agile?
Code Build Test Release Deploy Operate
Popular Agile Methods
DevOps

16. DevOps Principles
The Three Ways
System Thinking
Amplify Feedback Loop
Continuous Improvement
CAMS
Culture – People,
Process, Tool
Automation –
Infrastructure as Code
Measurement -
Everything
Sharing – Visualization,
Feedback

17. Shifting Left

18. Smaller Batch Size
Large batch size create bottleneck and takes more time to
complete work
Small batch size helps in reducing waiting time so increase
throughput
Release daily vs Monthly release
