Delivering anti-fragile systems may require us to challenge traditional ITSM approaches. With the rapid ascension of DevOps, IT decision makers, need to understand the perceived need for a “new way” to deliver value from IT. In this presentation we look at the key concepts and enablers underlying the DevOps Movement and place it in the wider context of Agile, “Anti-Fragility” and most importantly ITIL. You will learn about: · What DevOps is (and is not) · Key models used to conceptualise DevOps · Anti-Fragility and the behaviour of complex systems · How DevOps and ITSM intersect · DevOps Transformation and how it can help deliver business value. DevOps and ITSM intersect

- 33. DevOpsGuys “You will be assimilated” “Anti-fragile organisations seek out and embrace change – they are inherently “outward-focused” and seek to be continually learning, adapting and assimilating (not hiding behind the walls of their castle, content in their robust impregnability).” -TheOpsMgr http://blog.devopsguys.com/2013/07/17/devops-antifragility-and-the-borg-collective/
- 34. DevOpsGuys “You will be assimilated” “Likewise, DevOps seeks to be “anti-fragile” by embracing change (and disorder a la Chaos Monkey) whilst incorporating feedback mechanisms (the “3rd Way” of DevOps) to ensure that learning is correctly assimilated.” - TheOpsMgr http://blog.devopsguys.com/2013/07/17/devops-antifragility-and-the-borg-collective/

- 36. DevOpsGuys Embrace Chaos! “One of the first systems our engineers built in AWS is called the Chaos Monkey. The Chaos Monkey’s job is to randomly kill instances and services within our architecture. If we aren’t constantly testing our ability to succeed despite failure, then it isn’t likely to work when it matters most – in the event of an unexpected outage.” http://luckyrobot.com/netflix-chaos-monkey-keeps-movies-streaming/ http://www.codinghorror.com/blog/2011/04/working-with-the-chaos- monkey.html
