Agenda n Open source & Enterprise n Using open source software ¡ Risks & Suggestions n Joining open source development ¡ Risks & Suggestions

OSS is pervasive in enterprises n Actaute survey [1] n Gartner survey[2] Oct. 2009 Nov. 2008 15% 85% 【1】http://www.actuate.com/download/OpenSourceSurvey/oss2009.pdf 【2】http://www.gartner.com/it/page.jsp?id=801412

Enterprises are pervasive in OS n Two good examples ¡ Linux kernel contribution break-down [1] Company n 186 companies Personal contributed to v2.6.24 Unknown ¡ Microsoft turnaround n Platinum Sponsor of ASF in 2008 & 2009 n Contributed code to a number of open source projects, including Linux Kernel in July 2009! Microsoft 【1】https://www.linuxfoundation.org/publications/linuxkerneldevelopment.php

Enterprise roles in OS n User ¡ Run for daily operation ¡ Incorporate into product/service n Development contributor ¡ Code donation ¡ Employee participation n Leader n Service provider ¡ Technical support ¡ Consultancy: legal, process, risk assessment, … ¡ Education/Training ¡ Solution/Integration n Sponsor ¡ Fund, facility/infrastructure, software, …

Agenda n Open source & Enterprise n Using open source software n Joining open source development

OSS Benefit & Cost n High quality n Service availability n Zero license fee n Skill requirement n Openness/Freedom n Migration cost n Flexibility n Training cost n Transparency n Legal risk

Mitigating the system risks n Set up a governance system ¡ Determine the strategy (position, risk preference, etc.) ¡ Set up adoption review/approve process ¡ Set up daily management system n A central approved list/repository ¡ Conduct education

Legal risk in using OSS n Copyright ¡ Uncertain “pedigree”, SCO case ¡ Contamination n Patent ¡ Possible patent infringement, MS v.s Linux case n License ¡ Copy-left, Cisco Linksys case

Mitigating the legal risks n Do due-diligence investigation ¡ Source code scan ¡ Author background investigation n Get professional legal advice n Buy service

Evaluating OSS maturity n Outstanding leaders n Diversified community n Wide user base n Active development n Mature vulnerability management n Well-written documentation

Usage pattern n Run for internal use ¡ Most cases n Run to provide service to 3rd parties ¡ Most Internet service companies, including Google n Redistribute to 3rd parties ¡ Product ¡ Solution Caution!

Customization pattern n Take and fork ¡ IBM Lotus Symphony n Collaborative development ¡ IBM & Eclipse ¡ IBM WebSphere Community Edition & Apache Geronimo n Some point in-between ¡ Google: Apache Harmony, Linux

Agenda n Open source & Enterprise n Using open source software n Joining open source development

Motivations n Redistributing n Providing service n Driving standards n Disrupting competition n Building eco-system n User centered design

Legal risks in joining OSS dev n Contamination & Virus effect n Patent exposure n Mitigation suggestion ¡ Draw a fine line between proprietary code and open source code, set up review/approve process as required ¡ Conduct necessary education

Infrastructure support Open Source Community 3. Check in/out External community code repo 4. Smart Merge 2. Create Patch 5. Notify 1. Check in/out Internal code repo Merge Log and Continuous Developer Integration workstations

Internal open source n Run projects inside an enterprise in an open source way ¡ 20% project? ¡ Innovation incubation

Community-driven Commercial development n Open development ¡ Source code available ¡ Transparent development ¡ User interaction n Commercial license n Examples ¡ Project Zero (http://www.projectzero.org/) ¡ Rational Jazz (http://jazz.net/)

Summary n Open source is pervasive in enterprises, and enterprises have become the key driver of open source. n Use open source with caution. n Join in open source development with caution.
