The DevOps Transformation

DevOps promises to transform the way we work. By creating reliable, secure distributed systems that can also be rapidly evolved in response to user feedback, we can create lasting competitive advantage. In this talk Jez will describe how to implement devops principles and practices, how to overcome typical obstacles, and the outcomes DevOps enables.

1. @jezhumble | #jenkinsworld | august 31, 2017 the devops transformation
2. @jezhumble core principles and practices the problem (why devops matters) how does devops help? how to get there common obstacles agenda
3. @jezhumble “the enterprise” Project A Project B Project C DBAs Infrastructure team Service desk Value stream Operations Engineering Business Ping!
4. @jezhumble Project A Project B Project C DBAs Infrastructure team Service desk Value stream Operations Engineering Business Ping! Project D Let’s create a new product enterprise projects
5. @jezhumble Project A Project B DBAs Infrastructure team Service desk Project D We’re going agile! Oh no! Oh no! Value stream Operations Engineering Business
6. @jezhumble Project A Project B DBAs Infrastructure team Service desk Value stream Operations Engineering Business Project D Our test-driven code follows SOLID principles Shame it doesn’t work Change management
7. how devops helps
8. @jezhumble devops movement a cross-functional community of practice dedicated to the study of building, evolving and operating rapidly changing, secure, resilient systems at scale
9. @jezhumble what is continuous delivery? The ability to get changes—features, configuration changes, bug fixes, experiments—into production or into the hands of users safely and quickly in a sustainable way.
10. @jezhumble the iron triangle

12. @jezhumble time to restore service lead time for changes release frequency change fail rate it performance http://bit.ly/2014-devops-report

14. @jezhumble the alignment trap “Avoiding the Alignment Trap in IT,“ David Shpilberg, Steve Berez, Rudy Puryear and Sachin Shah MIT Sloan Management Review Magazine, Fall 2007.
15. @jezhumble how quickly can I get a critical fix to users? how quickly can i get feedback? how quickly can I restore service? how quickly can I validate if a feature is valuable? why lead time is important
16. @jezhumble “Evaluating well-designed and executed experiments that were designed to improve a key metric, only about 1/3 were successful at improving the key metric!” do less Kohavi et al, “Online Experimentation at Microsoft” | http://stanford.io/130uW6X
17. core devops principles and practices
18. scrum- fall water-
19. @jezhumble build quality in “Cease dependence on mass inspection to achieve quality. Improve the process and build quality into the product in the first place” W. Edwards Deming
20. Mainline Server Develop Build Build pull Local Workstation Build push ✔ Done!
21. Mainline Server Develop Build Build pull Local Workstation Build push ✔ Done! Everyone Commits To the Mainline Every Day
22. @jezhumble continuous integration at scale Jason Leyba | http://queue.acm.org/blogposting.cfm?id=78323
23. John Penix | “Large Scale Continuous Testing in the Cloud” | http://bit.ly/1BYMf70
24. @jezhumble deployment pipeline
25. @jezhumble different types of testing Functional acceptance tests Showcases Usability testing Exploratory testing Unit tests Integration tests System tests Non-functional acceptance tests (performance, scaling, ...) Business facing Technology facing Critique project Support programming AUTOMATED AUTOMATED MANUAL MANUAL / AUTOMATED
26. @jezhumble infrastructure-as-code
27. common obstacles
28. it’s about culture and architecture not process, tools, organizational structure
29. @jezhumble high trust culture Westrum, “A Typology of Organizational Cultures” | http://bmj.co/1BRGh5q how organizations process information
30. @jezhumble internet architecture Success on the web depends on “the ability to consistently create and deploy reliable software to an unreliable platform that scales horizontally” Jesse Robbins, “Master of Disaster” @ Amazon| @jesserobbins | http://oreil.ly/1HRKUVE
31. @jezhumble unreliable platform resilience, security, scalability, deployability, testability are architectural concerns

34. @jezhumble strangler application
35. You build it, You run it werner vogels, cto, amazon | http://bit.ly/11UJjmN
36. Project A Project B Project C DBAs Infrastructure team Service desk Value stream Operations Engineering Business Treat these services as if they were products
37. @jezhumble think product Service desk Value stream Operations Products / Services Ping! PaaS Ops management
38. @jezhumble talk to other teams agree and communicate measurable business goals give teams support and resources to experiment keep going achieve quick wins and share learnings the journey “6 Steps To Survive A DevOps Transformation” | http://ubm.io/1dKJajR
