2. Spoiler: It’s all about culture
3. The End

5. Our Adoption Story Evaluate Testing the Technology • 0-60 in no time • A little weird • Works great on my laptop • Hard to fit into existing environment Quick Win First Prod Service Traits of a successful first-time container • Easy • Stateless • Documentable Benefit Standardize Bring into the Fold • Getting support from others • Managing lifecycles • Dealing with variety • Enterprise-ready

7. Workflows Developer-centric
8. Build Developer builds app and environment into image locally Developers commit image to testing Test Developers deploy image to production Deploy
9. Where are the sysadmins?
10. Environment Developer builds app and environment into image locally Build Developers commit code to testing Test Developers deploy code to production Deploy Operations gets paged (and runs servers) Maintain Sysadmins create “blessed” base-images
11. Architectures Disposable & Info-centric
12. Musings on Architecture Image Registries!
13. Musings on Architecture Network Storage!
14. Musings on Architecture Jenkins! (CI/CD Servers)
15. Musings on Architecture Atomic Hosts! (or CoreOS)
16. Musings on Architecture Orchestration!
17. Musings on Architecture Bare Metal vs. Virtual Machines!
18. Musings on Architecture My (unsophisticated) tests: https://github.com/DockerDemos/vm-docker-bench Bare Metal vs. Virtual Machines!
19. Pitfalls and AH-HAs DISCLAIMER: I don’t have all the answers
20. Pitfalls • New and Strange • Storage is Hard • Everything is (too) Fast • ...and Complicated • We’re not all Rockstar Gurus
21. Ah-Ha! • Timescale is everything • Automation is everything The Lightbulb Moments
22. • Timescale is everything • Automation is everything Ah-Ha! Honorable Mention Monitoring & Logging (almost everything) The Lightbulb Moments
23. Getting back to Culture
24. Culture Containers cause: • Shift in Job Roles • Changes in Policy • New Workflows • Cross-Discipline Collaboration • Anxiety ( & Excitement!) Change
25. Our Current Organization Developers Sysadmins • Build customized servers • Configure environment • Work with developers • Setup monitoring/backups /storage Operations • Manages physical hardware • Gets paged • Remediates problems with runbooks • Escalate to sysadmins • Write and maintain the apps • Work with clients • Drive environment decisions
26. Our Future Organization (maybe) Developers Operations • Manages hardware • Gets paged & Remediates problems • Escalate to developers Perhaps ex-sysadmins who likes hardware & infrastructure • Write and maintain the apps • Work with clients • Build environment in images Perhaps ex-sysadmins embedded as the “systems person” Automation
27. Re-think what you have done
28. Containers are new Culture
