What is DevOps and why should I care?
‫‏‬The Development team (Dev) is responsible for building solutions to support rapidly
changing business needs with high quality.
‫‏‬Compress delivery cycles — Experiment and Learn
‫‏‬The Operations team (Ops) is held accountable for response times, stability and
efficiency, and is focused on how to reduce business disruptions.
‫‏‬Institute controls — Tightly govern change
Why does it take so long to get a new requirement into production?
The ROI/business case that we started with no longer exists!

‫‏‬Strive to produce work
while compressing
delivery cycles.

DevOps is applicable to all delivery models
• Leveraging automation and DevOps
principles can drive better outcomes
• Key benefits of DevOps are realized in areas
like integration testing, UAT, etc.
• DevOps is critical to maintaining quality at
the higher pace of an Agile model

Continuous integration and deployment is at the heart of DevOps
• Developers write code locally.
• Developers commit their changes to
a centralized code repository

• Get metrics on the newest build and
deployment
• Stakeholders receive real-time notifications
• Learn and prioritize
Measure and learn
• New code is detected and kicks off an
automated build
• Generated build errors are automatically
published
Build
• The newly created build is automatically
tested
• Automated testing can include unit,
integration and other types of tests
Test

Infrastructure automation
• Standardized environments allow for
“copy/paste”-like functionality
• Automated deployments can reduce the chance
of errors and save time
• Infrastructure is developed like code and can
be iterated on and leveraged for new versions

Testing automation
• Automated unit tests can reduce the number of
defects early in the software lifecycle
• Interface-based development supports testing in
isolation
• Change tolerance is important given ever-changing
requirements
• Automated regression testing verifies that quality is
a quickly changing environment

Potential benefits:
 ‫‏‬Reduce negative side-effects
 ‫‏‬Integration issues are fixed early
 ‫‏‬Real-time health checks

Early warnings and insight
Tool-based monitoring and alerting
‫‏‬Tools monitor infrastructure and application performance and automatically notify operations when there is
an anomaly:
• Application Performance Monitoring (APM) tools facilitate monitoring of application performance and the
interaction with other systems
• Collect and analyze massive streams of generated machine data

• Establish the need
• Build new skills that are required
• Begin planning for automation
• Communicate and cooperate
• Employ‫‏‬a‫“‏‬services”‫‏‬thinking‫‏‬mentality
• Get experts on board.
• Commit—both business and IT
Where do you start?
Bottom line
By arming IT with the tools to automate and integrate their core disciplines, real-time DevOps has the opportunity to
profoundly impact the IT shop—accelerating IT delivery, improving quality and better-aligning IT with the business
