DevOps and the industrial revolution
- 1. DevOps: how the Industrial Revolution got us here Jonathan Fletcher Enterprise Architect, Technology and Platform Lead v1.1
- 2. Me • Jonathan Fletcher • Architect in Hiscox Group IT since 2012 • Ex Dev • Ex Ops • http://enterprisedevops.blogspot.com • http://www.devops.com • @FletcherJofanon 2
- 3. The 1700’s 3
- 4. The industrial revolution • Occurred in England some time in the mid- 1700’s • Largely in response to textile competition arising from India 4
- 5. Boring…so what? • Led us from hand manufacturing techniques to machines • Led to new processes including increased specialisation of roles and new ways of scaling production 5
- 7. Luddites 7
- 9. Now 9
- 10. IT today 10 I’m a business analyst I’m a DBA I’m a developer I work in support I’m an infrastructure engineer I’m a business stakeholder I’m a release manager I’m a security consultant
- 11. Common complaints • “Throw it over the wall” behaviour - it’s not my problem • Lack of holistic understanding of the software delivery lifecycle • Slow pace of change • Expensive cost of change • Late discovery of issues in the project lifecycle • Unaligned goals and incentives – pulling in different directions 11

Alignment of goals Moreprocessreviews Morechangecontrolreviews Moredeploymentfreezes Morestandardscontrolboards Morefrequentchanges Lowertoleranceforoutage Morecomplexapplications Morecomplexdeployments Do more! Do less! RFC’s CAB Deployment guide Rollback guide Daily status calls Staff availability Issue tracking Environment booking Escalation processes Emergency processes Small change processes etc etc Mr. Dev Mr. Ops
- 13. Is DevOps the right name? • Why do we think the issue of working well together and aligning goals is limited to Development and Operations? • Shouldn’t everyone involved in the change process should work together to accomplish shared goals? • DevTestBizThingyOps DevTestBizThingySecOps should be the real name © J.Fletcher
- 14. DevOps – so what is it? 14 • “Bad behaviour arises when you abstract people away from the consequences of their actions” – Jez Humble • DevOps is a culture of empathy, shared goals and incentives
- 16. Shared goals, incentives, empathy & transparency 16
- 17. Automation benefits • 150 deployments in the last 3 days in one application alone • The week before go-live on our biggest ever change program we reduced 17.5 man days of effort to about 10 minutes • Help enable changing a 10 week change cycle down to 2 weeks • We went from 1 person knowing how to do to do a release to thousands (kind of!) 17
- 18. DevOps has visibility at the highest levels 18 Project Sponsor My Boss
- 19. DevOps – how? 19 1. Employ the right people in the right team structure (and yes that includes you security chaps!) 2. Empower the team – let them make the right decisions 3. There are processes and tools that help align working practises to achieve empathy and shared goals (such as increasing the pace of change) 4. Commonly large amounts of automation is prevalent in a DevOps environment to create metrics, reduce manual wasted effort and increase the pace of change

- Ned Ludd. Low skilled cheap labour fears
