• Qualities of Open Source overtake Cost as primary adoption driver
Question:
“I am a Chief Information Officer (CIO). I want to use Open Source Software in my company to lower costs but I have heard horror stories.
How can I manage to do it and still keep my job?”
#1 - Strategy
• Define criteria and guidelines for choosing Open Source
– Features, maturity, frequency of releases, bug fixes– Size and health of Community, Governance– Commercial Support & Licensing
• Map existing Open Source usage
– What, Where, Why– Who supports it– How is it acquired/distributed
• Measure TCO
#2 – Architecture
• Open Source is about Choice
– Do not base your architecture on Products
– Avoid vendor lock-in, proprietary or not
• Embrace Open Standards
– Reference Architectures*
– Interfaces (APIs)
– Data Formats
*e.g. Java Enterprise Edition (EE) providesan excellent base for enterprise applications.
#3 – Skills

– Adopt Open Source development practices & tools
• Educate your People
– Trainings, Conferences, Certifications
