  2. 2. Agenda n Open source & Enterprise n Using open source software ¡ Risks & Suggestions n Joining open source development ¡ Risks & Suggestions
  3. 3. OSS is pervasive in enterprises n Actaute survey [1] n Gartner survey[2] Oct. 2009 Nov. 2008 15% 85% 【1】 【2】
  4. 4. 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】
  5. 5. 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, …
  6. 6. Agenda n Open source & Enterprise n Using open source software n Joining open source development
  7. 7. 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
  8. 8. 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
