Hello I’m mr. DevOps! • No it’s not a single person! • No it’s not a role! • No it’s not a title!

DevOps-team!

No it’s not a “yet-another-new-team” in the company!

Automated testing IS NOT DevOps It’s called Continuous Integration!

Automated infrastructure IS NOT DevOps It’s called Infrastructure As Code!

Automated deployment IS NOT DevOps It’s called Continuous Delivery & Deployment!

2000- From product to service shift

When consumer buys a car (product) he wants that it has all possible features, but…

…when he uses taxi (service) it doesn’t

matter what features it has, just that it takes him from A to B

2009: Lean Startup - Minimum Viable Product - Build – Measure – Learn - Continuous Deployment - Split Testing - Actionable Metrics 22

Minimum Viable Product

23

New requirements for developers and operations • Fast, tested, fail safe, small changes continuously deployed to production • Measure, share visibility and provide feedback of users to business, continuously. • Small experiments, test assumptions, fail fast and learn! • Capability to pivot rapidly and often

TADAA! And that’s what it’s all about

Three ways

Feedback

System thinking

Culture Ops (customer)

Dev (business)

By Gene Kim

Think your whole development process as a system where single change is the item.

How can you make the process

better, faster, smooth and error safe? -System thinking

If you don’t measure, you cannot improve.

It’s like driving car eyes blinded! -Feedback

Understanding that repetition and practice is the prerequisite to mastery!

-Culture of continuous experimenting and learning

DevOps “Gives capability to do rapid and experimental business, safely”

Where should we start?

33 Group up, share knowledge

Understand Your processes

Pinpoint the bottlenecks and pain points

Take small steps, together

Culture How we can encourage to collaboration and communication? Automation Is there any repetitive, error prone work to automate? Lean Focus on removing waste, delivering value in small batches Measurement Provide feedback to everyone! Sharing Share everything!

REMEMBER: It’s not just deployment

How much does it cost?

Would you made this change?

It’s not free, but worth it in long term.
