LinuxCon NA: Xen Project, Lessons Learned LinuxCon NA: Xen Project, Lessons Learned Presentation Transcript

  • Lars Kurth Community Manger, Xen Project Chairman, Xen Project Advisroy Board Director, Open Source, Citrix lars_kurth
  • Was a contributor to various projects Worked in parallel computing, tools, mobile and now virtualization Long history in change projects Community guy at Symbian Foundation Learned how NOT to do stuff Community guy for the Xen Project Working for Citrix Accountable to Xen Project Advisory Board Chairman of Xen Project Advisory Board
  • 0 50000 100000 150000 200000 250000 2006 2008 2010 2012 2014 Projected Source: The 2013 Future of Open Source Survey Results More than 1 Projects Million Today
  • Late 90’s Today Individuals & Hobbyist's Still about Individuals But, a majority are employees Companies have a huge stake
  • and pressure to succeed
  • Features How many users you have How many vendors back you How you are seen in the press … Different Management Disciplines
  • can help you succeed
  • Neutrality / Perception Support Infrastructure Expertise / Mentoring Vendor Network … BUT: You still need to do all the right things
  • Case Study
  • An Open Source Hypervisor > 10M Users Powering some of the biggest Clouds in Production Amazon Web Services, Rackspace Public Cloud, Terremark, … Several sub-projects Xen Hypervisor, XAPI management tools, Mirage OS Linux Foundation Collaborative Project Sponsored by Amazon Web Services, AMD, Bromium, Calxeda, CA Technologies, Cisco, Citrix, Google, Intel, NetApp, Oracle, Samsung and Verizon 10 years old
  • Fixes that were applied (there may be others) Effect this had Magnifying effect Symptoms Consequences for Xen Four Key Issues At the end : Reflection & Tools
  • Unwritten Rules Undefined Roles Lack of Upfront Collaboration
  • Hard to join the project Vendors got frustrated Hard to work with the project
  • 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 Developer list traffic : Q3 2003 - now Xen Governance Canonical drops Xen RedHat drops Xen in RHEL6 Roadmap & Release Management Another key vendor nearly dropped Xen Technical Coordination Team 1st KVM releaseGrowth potential was limited early Xen becomes LF Collaborative Project
  • 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% 2010 2011 2012 2013 (H1) UPC Spectra Logic Redhat iweb GridCentric Calxeda Fujitsu (Misc) AWS (Academia) John Hopkins University AMD Linaro Oracle NSA Intel
  • Theory: vendor neutrality = more contributors Early indicators: Individual Contributors have doubled Advisory Board members are becoming contributors Momentum in new market segments is building Advisory Board is developing a long term project Vision Creating incentives to become more mature
  • Inwards focus – Not working with upstreams (branched kernel and QEMU) – Not working with distros (users are not “our” problem) Created “pain for distros” Intercommunity Friction Introvert Community Image Problem
  • 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 Developer list traffic : Q3 2003 - now IBM, VMware, Red Hat and Citrix Agree on PVOPS in Linux kernel Linux Guest support for Xen Linux Host support for Xen Upstream QEMU complete Actively working with distros
  • Improved Relationships & Trust Xen Developers Care about Users Xen becoming easier to use Improved Image in the media and FOSS community
  • Significant increase in Goodwill from the LINUX community Working with upstream & downstream projects is easier Collaboration happening earlier than in the past Automotive, Mobile, Embedded
  • 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 Developer list traffic : Q3 2003 - now Focus on events for the existing community only Enough Papers Enough Talks Enough Communication By enough vendors Xen Books Competing Projects Excelled at Communication Change of Guard Empty Promises Blog 1 Person
  • Project became an “invisible man” Belief that Xen is not open source Slowed the growth of the user base Perception: the project is “dead” Constant stories in the press that the project is dying First: Defiance – this is all “Fud” Then: Project started to believe this too
  • 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 Developer list traffic : Q3 2003 - now Confidence Building Community Blog Events v2 Community spokespeople
  • Project perception has changed Neutral to positive No more “Xen is not OSS / Xen is Dead” New influx of people to the project 0 5 10 15 20 25 30 2010 2011 2012 2013 (H1) Talks / Events / Orgs
  • Increase in Goodwill in the FOSS Community No more Xen bashing Significant increase in social media activity Linux Foundation Expertise Press Releases and other LF channels Managing Events Xen Project Advisory Board : Marketing and PR Committee
  • CompaniesCommunity
  • Within Citrix : via the process of “giving up control” Big enough plan to catch the attention of senior management Forced decision makers in the hierarchy to consider the value of FOSS Amongst companies supporting the project financially Forced decision makers in contributors to go through a similar process
  • Governance and Neutrality Matter Projects don’t exist in isolation Poor Marketing and Communication can kill you Good project sponsors can make a difference Being part of a Foundation can make a big difference A project needs to constantly evolve
  • License & Development Model Linux (but also BSDs) are key components in a Xen stack Most Xen contributors were Linux Foundation members Vendor Friendly Strengths: PR, User Outreach, Events Management, …
  • Multi-discipline Complexity
  • Follow Industry News Follow Project News Adopt Software Engage with Users Trial Software Engage with Industry Evangelize Contribute Customize Lead Think of the funnel boundary as a permeable membrane, not a fixed border It can take >2 years for changes at the top of the funnel to make a difference at the bottom The Funnel has feedback loops: what happens at the top can affect the bottom
  • Follow Industry News Follow Project News Adopt Software Engage with Users Trial Software Engage with Industry Evangelize Contribute Customize Lead Control the permeability and shape of the funnel Activities Attributes Events Project Scope E.g. Xen on ARM, Mirage OS Increase the width and thus the potential market for the project How can we influence how the Community Funnel works? Some items are in your control Others - such as what the competition does - are not!
  • Follow Industry News Follow Project News Adopt Software Engage with Users Trial Software Engage with Industry Evangelize Contribute Customize Lead Example: Factors influencing early stages of open source software adoption Documentation Ease of Use Training On-boarding
  • Follow Industry News Follow Project News Adopt Software Engage with Users Trial Software Engage with Industry Evangelize Contribute Customize Lead More People drop out Funnel becomes narrower Negative Feedback: vendors may stop contributing Bad Press Example: Negative feedback loop
  • The Community Funnel is an excellent internal sales tool Reason: Sales and Business people understand funnels It helps you understand what is happening It helps prioritize what to focus on Covers the time dimension : some issues take longer to fix than others Forces you to consider the “Big Picture”

  • To succeed, a wide range of “community” and “management” tools need to be applied continuously
