Demystifying DevOps - it's not Agile, but they're friends
DevOps aims to help organizations rapidly produce software by improving the interdependence between software development and IT operations. While DevOps has been around for a long time, there is still confusion about what it means. True DevOps culture focuses on shared ownership and a philosophy of fast feedback, customer focus, and optimizing for speed and quality rather than specific roles. Good DevOps looks like simple communication, co-location of teams when possible, and infrastructure defined as code.

Editor's Notes
- #3 DevOps things for 10yrs Work for ThoughtWorks in SF Eating my way round the world, solving problems for clients in various industries
- #6 using “rapidly” and forgetting “quality” is dangerous, but I like “response”.. means it’s answering a problem that existed, but wont necessarily always exist.
- #7 DevOps has been around for years as a discipline, and coined “DevOps” for 5years ref: Patrick Debois - of DevOpsDays fame. - 2009 Poll: who feels they have a grasp of what devops is and isnt?
- #8 Every employer is calling for DevOps (even ThoughtWorks). But what do they mean? LinkedIn is headhunting us by word searching! …which is great (for us!) but it’s not helping the situation
- #9 Gives rise to: DevOps experts exist as heroes exist and counteract shared ownership Also, needing a pipeline doesn't mean you need a DevOps specialist
- #10 Other people are frustrated…or at least confused, people saw the blog post right? “How ‘DevOps’ is Killing the Developer” so it’s not just me.
- #11 Specialism is good but Devs being more Ops-minded - GOOD! Ops folk being more Devvy - SURE! Coding Puppet isn’t DevOps - thats infra coding - but it’s a good bridge of skills!
- #12 Agile against DevOps?
- #13 Agile is the same as DevOps?
- #14 Agile entails DevOps?
- #15 My view: they’re pals! - mutually exclusive philosophies …with some overlap or, common interests:
- #16 Visual feedback - agile boards vs Monitoring dashboards Value is about success with the product customer, or consumer of the service - a dev team could be the customer of a DevOps initiative
- #17 DevOps is a philosophy NOT a ROLE Every project doesn't need a DevOps person. like QA’s - quality is everyones concern But a certain set of skills really helps fight the DevOps cause, so there’s this role that is neither solid Dev, nor Ops
- #18 Someone who has experience on both sides? Feels pain when others feel pain? maybe they contribute solutions to dev and ops land?
- #19 so what do we call it? i don't really mind.. but not DevOps Call it OpsDev (if you really want to screw with people) Perhaps you’re just the new wave of Ops Jedi Master, behavioural technician
- #20 I’ll leave you with how to spot bad and good devops
- #21 Bad Ops Team that only care about stability and uptime probably surly, know Linus Torvalds and unlikely to deploy your code without a huge document
- #22 Old school Developers… only caring about new features compiling hot fixes at home and asking Ops to deploy it in the morning. Naughty.
- #23 A Devops Team..is actually ok! under certain conditions. But in most cases a sign that something isn’t quite right. A friend of mine did a talk defending this. Ask me for details Mark Rendell DevOpsDays London 2013 http://devopsdays.org/events/2013-london/proposals/When%20you%20need%20a%20DevOps%20team

- #25 The Tool Junkie - a proliferation of the latest gadgets will become hard for the project to support
- #26 A DevOps person! What does this person do exactly? (apart from swan around citing Martin Fowler) Seriously though - If the problem isn’t strictly dev, or ops, this role becomes a catch-all and a bottleneck
- #28 the good! Ops participating in showcases, retros, inceptions and planning sessions Devs rotating through Ops - Show them how bad their logging is (and don’t let them attach a debugger)
- #29 A culture of valuable, respectful, concise communication Co-location: same room if possible. you just can’t beat it. And finally…
- #30 Again, it’s about breaking down barriers and empathising. This is done more effortlessly when emotions are engaged. “HugOps”
- #31 Lunch Ops
