4. Anti Pattern #1 - Config Mgmt = DevOps

Tools
Process
Culture

5. Anti-Pattern #2- Rebranding Ops as the DevOps team or Creating separate team
5
(Yet Another Silo)
Act as a change agent

6. Anti-Pattern #3 - Sell it as a buzzword

7. 7
Anti-Pattern #4 – Deploy Software Manually

8. 8
Anti-Pattern #5 - Manual Configuration of Production Environments

9. 9
Anti-Pattern #6 - Believe chef/puppet will solve all your problems 

10. Anti-Pattern #7 - Deploy to production after testing in Dev without testing in Production-Like

12. Traditional Dev and Ops Model
12
They don’t have common goals.
They don’t use the same tools
No visibility into one others’ processes
Characteristics of traditional Dev and Ops teams:
Development Teams
• Driven by change
• Focus is to deliver value
executing projects on
time and within budget
• Measured by improved
business capability and
agility
• Higher frequency of
releases
• Rapid pace of innovation
in tools and technologies Different implementation methodologies
Operations Teams
• Driven by stability
• Focus is to keep the
enterprise running with
less to zero downtime
• Measured by uptime and
stability of the production
system
• Encourage fewer releases
• Typically small teams
consumed by fire-fighting

13. Symptoms and causes
13
The project was kicked off last week. The dev environment isn’t ready
yet.
There are multiple tracks in the project. Build is broken more often than
not. Takes a lot of time to identify the issue.
Application is deployed to QA environment successfully. But I can’t login
to the application.
Tedious testing cycle. Takes too much time to setup test bed, execute test
cases, report results and even more time to repeat this cycle.
Takes too much time to follow the release notes and deploy the
application.
No easy way to
spawn

14. Agile is needed in all the phases of SDLC. Not just in development.

Continuous Build
and Integration
• Key part of Agile
development
• Integrate code from
multiple tracks/modules
as early as possible
• Unit tested build delivered
• Assign build version before
deploying to QA
Continuous
Testing
• QA the code for functional
and non-functional
aspects in a prod-like
environment
• QA reports defects on a
specific build version
• Dev fixes the defects and
delivers another build.
This loop continues till QA
certifies the build
• Improves confidence in
the entire team if code is
being tested regularly
Continuous
Deployment
• Objective is to get the
system to the users’ hands
as often as possible
• Deploy the QA certified
build in prod
• Build tools to automate
the deployment
• Opportunity for Ops to
provide feedback to Dev
on the structure of the
build early in the life cycle
• Continually deploying
code will improve the
quality of tools and make
the deployment seamless
Continuous
Monitoring
• Use monitoring tools to
measure system and
application health
• Opportunities to identify
bottlenecks and issues
early
• Communicate
performance/scalability
issues to dev early
Continuous Delivery
