23. Who’s embracing Open Source?
24. The OS Pricing Model • Open Source software doesn’t mean no revenue. • The Source Code may be freely available, but that doesn’t mean the software itself has to be. • Dual Licensing allows for a smarter business model • Revenue streams from additional product services: ★ Ongoing professional services ★ Offering the Software as a Service ★ Selling of branded merchandise
