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

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
