  • 1. #unidevops Software Operability, Run Book Collaboration, and DevOps Matthew Skelton 27th February 2014 DevOps Summit, London, UK www.devopssummit.com @matthewpskelton softwareoperability.com
  • 2. • Software Operability • Run Book Collaboration • Making Operability Work • Questions #unidevops Agenda
  • 3. • Software systems since 1998 • Continuous Delivery specialist, DevOps enthusiast, Operability nut • London Continuous Delivery meetup group - londoncd.org.uk • Experience DevOps workshops • PIPELINE Conference #unidevops Background
  • 4. #unidevops Software Operability
  • 5. • • • • Definitions Examples Why focus on operability? How DevOps can help #unidevops Software Operability
  • 6. #unidevops Operability?
  • 7. • Cognates: – Opera – Operate – Operational – Inter-operability #unidevops Etymology of Operability?
  • 8. #unidevops
  • 9. • Operability: the properties of a system which make it work well in Production #unidevops Software Operability
  • 10. Since 1929, Mallorca, Spain #unidevops Operable Systems
  • 11. • David Copeland (@davetron5000): “How your software runs in production is all that matters. The most amazing abstractions, cleanest code, or beautiful algorithms are meaningless if your code doesn’t run well on production.” • http://www.naildrivin5.com/blog/2013/06/16/production-is-all-that-matters.html #unidevops Software Operability
  • 12. • • • • • • • • • Deploy Monitor Diagnose Debug Query Control Inspect Clear ... #unidevops Operational Criteria
  • 13. #unidevops “Non-Functional”
  • 14. • Hooks (internal APIs) for: – Logging – Monitoring – Diagnostics – Health checks – Data clear-down – Service / daemon / container control #unidevops Shaped by Operability
  • 15. #unidevops Ops Folk are Users Too!
  • 16. #unidevops
  • 17. • Deploy more rapidly, frequently • High cost of Production outage • Systems now more complicated #unidevops Why focus on Operability?
  • 18. #unidevops Outages are Embarrassing!
  • 19. #unidevops Operational considerations
  • 20. #unidevops Operational considerations
  • 21. #unidevops Operational considerations
  • 22. • DevOps is one way to address poor operability • Improved collaboration and communication between Dev teams and Ops teams • Example: Run Book Collaboration #unidevops How DevOps can help
  • 23. #unidevops Run Book Collaboration
  • 24. • Feedback loops and learning • What is a run book? • How can run book collaboration help operability? #unidevops Run Book Collaboration
  • 25. Gene Kim: http://itrevolution.com/the-three-ways-principles-underpinning-devops/ #unidevops Feedback Loops
