As an evangelist, I often get asked the following question at conferences:
How does Sun make money on open source?
Although I do have an aswer to this question, it is better to provide an answer directly from our CEO, Jonathan Schwartz. I just read this Q&A with Jonathan and thought it was a very clear explanation of Sun's open source business strategy. I'd like to mention that Sun has been open sourcing lots of software during last fiscal year (including the crown jewels like Java, and Solaris before that) while the software business grew by 13% during last fiscal year. So it is clear that Sun's open source strategy is paying off.
