"Still, the market is polarizing into open-source haves and
have-nots. IBM sells billions of dollars worth of hardware,
middleware, and IT services associated with Linux each year, says
Inna Kuznetsova, the company's director of Linux strategy. And
Oracle has made Linux an important platform for running its
database and applications. Yet sellers of Linux tech support are
often left in the lurch as companies pay for support only for the
servers that run important corporate databases and applications,
while choosing free versions of the software for Web servers, which
are far greater in number."
