  • Pre-empt introductions with a simple yet powerful statement.Spirit of community and collaboration.
  • Main – Help bootstrap technology groups around Midwest region.Began tech career diving feet first into co-founding ISP, multiple downturns and upturns, multiple generations of Automation technology, 7 yrs Software Eng, 3 yrs leadingApply learning in different contexts – industries, maturity, organizations, cultures
  • Context around “No Assholes”Have respect for others who may be less experienced, have less exposure or maybe just do not learn as fast.Have respect for those who may have limited time and/or realize some topics are not easily conveyed.Mutual Respect
  • Mutual RespectIt’s not so much about just technology but the complete interaction of people, process and technology used.If you can’t get along with people, you are missing a big part of the equation.
  • DevOps is bigger than Dev and OpsSpans other tech groups, dba’s, QASpans business side tooGet out of the “us” vs “them” mentality
  • Things to decide after prezoTopic Coverage possibilitiesMeeting frequency[Come up with several topics]
  • DevOps is bigger than Dev and OpsSpans other tech groups, dba’s, QASpans business side tooGet out of the “us” vs “them” mentality
  • Automation nothing new but the complexity we just talked about has really proliferated with enabling platforms such as virtualization and cloud.
  • Infrastructure As Code is nothing newIt’s been growing in popularity, was always a consideration with cutting edge Bay Area tech firms.The inflection point has given it escape velocity.
  • CFEngine – Mark BurgessPuppet – Luke KaniesOpscode – Adam Jacob
  • SALES-> “Infrastructure As Code” Opscode positionObvious, several articles on Oreilly discussing studies and data from companies using “secret sauce” tech which is really “Infrastructure As Code” VS traditional methods including enterprise tech.http://radar.oreilly.com/2007/10/operations-is-a-competitive-ad.html
  • SALES-> “Infrastructure As Code” Opscode position“Infrastructure As Code” … core conceptSource code – Agile, leveragedev best-practices for managing infrastructure change.Configuration Repository – Source Code Repository, common methods used in software development for tracking the degrees of state change in a developing system.Data Backup – Separation of data from execution. Think of code/execution as the house and the data as the furniture and accessories that give it personality/distinction.Bare Resources – Primitives, an understanding of the core building blocks to easily support new platforms and make it intuitive to do so.
  • How does this apply to DevOps?So how many people recognize these characters? And I’m not just talking about Spock and Scotty, how many people recognize the traditional IT roles embedded in their behaviors.Metaphor Attribution – Andrew Shafer, now of Rackspace
  • And furthermore, we think these two roles have always pinned dev and ops against each other. Developers are measured based on the output of new functionality they churn out. Create a bunch of features, send them over the wall to Q&A/release/ops who are left to deploy and scale that new functionality while keeping the site up. Ops meanwhile, is really only tasked with just that, with keeping everything running as a sole focus. What is the single most common way to make a running site go down, introduce change…
  • Anyone know this book? Anyone catch Derek Hammer's talk before lunch?Jez Humble and David Farley's Continuous Delivery. Let's talk about that.
  • And this is what it looks like. Application and Infrastructure developers and operators check in their code to version control.
  • The commits (once approved) will get picked up by the continuous integration tool (like Jenkins), which will build the code, deploy to a test infrastructure and start testing.
  • That cycle of build, deploy and test repeats until it fails or gets to production. Catching issues and smoketesting your changes well before they get to Production.

  • Milwaukee DevOps MeetupDecember 5, 2012
  • “We are at our most productive when we share our thinking.One night of crazy brain-storming over a few beers is morelikely to produce more exciting results than 20 years’solitary study in the lab.”–Professor Howard Trevor Jacobs, Descartes Prize Winner Read more at redmonk.com - http://goo.gl/FEJyI http://redmonk.com/jgovernor/2004/12/15/the-pub-is-the-place-for-creativity-and-innovation/

  • Traditional Thinking Won’t Make the Grade … Before discussing the future, Let’s review the past. More importantly why “traditional” enterprise technologies will not cut it.
  • Unprecedented Growth AND Complexity … Scale x Complexity > Skills Inflection point forces disruption. 1980 1990 2000 2010+ Mainframe Client/Server Datacenter Cloud1980 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015

  • “Infrastructure As Code” Mantra“Infrastructure As Code” … The business, not just a tool Enable the reconstruction of the business from nothing but a configuration repository, an application data backup, and bare resources. As rapidly and elegantly as possible.
  • “Infrastructure As Code”• A configuration management system (DSL)• A library for configuration management• A community, contributing to library and expertise• A systems integration platform (API) http://www.flickr.com/photos/asten/2159525309/sizes/l/

  • Meet Dev • Little bit weird • Sits closer to the boss • Thinks too hard Don’t hate the player …Metaphor Attribution – Andrew Shafer, now of Rackspace
  • Meet Ops • Pulls levers & turns knobs • Easily excited • Yells a lot in emergencies Why you be hatin ?!?Metaphor Attribution – Andrew Shafer, now of Rackspace
