"If asked to name significant Linux organizations, Fujitsu Ltd.
might not be a company that comes immediately to mind. But to
underestimate the value Fujitsu brings to the Linux ecosystem would
be erroneous: the world's fourth-largest IT services provider and

"Just how big? Currently, Fujitsu is the number-two server
vendor contributor to Linux kernel development, behind IBM. Their
Linux deployments include the replacement of existing mainframes at
the Japan Ministry of Justice and the Tokyo Stock Exchange--systems
that are recognized as being among the strongest Linux deployments
in the world in terms of size and reliability.

in the Linux ecosystem? Like many other vendors, it was the
customer who guided the way."
