OSS : when, where, how?

Its important to understand that FLOSS does not

mean non-commercial

more expensive than proprietary ?

side by side do proprietary more reliable?

which is more secure?

which to choose? what to choose?

how to decide?

OSS : expensive?

"Our startup honestly wanted to use OSS products. We do not want to spend time for

any OSS bug fixing so our main requirement was -official support for all OSS

products-. We thought were prepared to pay the price for OSS products, but then we

got a price sticker shock. Now behold: QT is $3300 per seat. We have dropped the

development and rewrote everything to C# (MSVS 2005 is ~$700). Embedded

Linux from a reputable RT vendor is $25,000 per 5 seats per year. We needed only3 seats. We had to buy 5 nevertheless. The support was bad. We will go for

VxWorks or WinCE in our next product. Red Hat Linux WS is $299. An OEM

version of Windows XP Pro is ~$140. A Cygwin commercial license will cost tens

of thousands of dollars and is only available for large shops. We need 5 seats.

Windows Unix services are free. After all, we have decided that the survival of our

business is more important for us then 'do-good' ideas.

OSS : how to decide?

Establish a criteria for evaluating OSS products, as

well as procedures to adopt and maintain them.

Don't launch strategic initiatives without a thorough

risk assessment (e.g. Linux for desktop or for Back-Office is different!).

OSS : how to decide?

OSS is not 'the' or 'the only' solution

intelligently choose

look around, ask questions

number of users widely adopted stable release ~> 2 years

mailing list / user group / documentation / howto

regualarly updated / active development

similar project / alternative

number of developers

commercial support / internal man power for support

security / clean code / number of vulnerablities
