Dow Corning
"We're a global operation and have always used mainframes. Choosing Sun was a
higher risk than other choices, but they really impressed us with their
technology and commitment. Now that we've worked with Sun, if we had to do it
over again, we wouldn't even consider making a different decision. Sun is doing
an outstanding job."
-- Mark Smith, Manager of Information Technology Systems, Dow Corning
Hotmail, now owned by The Microsoft Corporation
This free Web-based e-mail service runs a mixture of Sun Solaris and FreeBSD.
Apache 1.2.1 is the Web server software. After Microsoft purchased the company
in December 1997, they tried to migrate to NT, but ". . . the demands of
supporting 10 million users reportedly proved too great for NT, and Solaris was
reinstated." Get the full story: Solaris calls Hotmail shots for Microsoft.
United States Postal Service
"The United States Postal Service deployed over 900 Linux based systems
throughout the United States in 1997 to automatically recognize the destination
addresses on mail pieces. Each system consists of 5 dual Pentium Pro 200MHz
(PP200) computers and one single PP200 all running Linux."
-- John Taves, Linux is reading your mail, April 8, 1998
Yahoo!
". . . A couple of days later we added a FreeBSD box to our cluster of Web
servers. Not only did it out-perform the rest of our machines, but it was more
stable. A few weeks into this experiment and we were sold. Although the price
was certainly attractive, it was the stability, performance, and access to the
source code that sold us. Ever since then we've used FreeBSD almost exclusively
for production as well as our development environment."
-- David Filo, Co-founder of Yahoo! (FreeBSD News, Issue 1)
