Joyent Names Bryan Cantrill Vice President of Engineering

Former Sun Microsystems Distinguished Engineer Takes on Cloud OS Innovation as the Latest Addition to Joyent's Growing Team

SAN FRANCISCO, July 29, 2010 - Joyent, a leading global provider of cloud computing solutions, today
named Bryan Cantrill as VP of Engineering. Cantrill will be responsible for
overseeing worldwide development focused on operating systems, including
building additional innovation into Joyent's SmartOS and SmartDataCenter.

For Joyent, the addition of Cantrill, an engineer named as one of the top
35 technologists under the age of 35 by MIT's Technology Review and an
Innovator of the Year by InfoWorld, represents the next step in continuing to
building out a team of world-renowned engineering talent.

Prior to joining the Joyent team, Cantrill served as Distinguished
Engineer at Sun Microsystems, where he spent more than a decade working on
system software, from the guts of the kernel to client-code on the browser
and much in between. Most notably, Cantrill co-designed and implemented
DTrace, a facility for dynamic instrumentation of production systems that won
the Wall Street Journal's top Technology Innovation Award in 2006 and the
USENIX Software Tools User Group Award in 2008.

Recently Bryan co-founded the Fishworks group at Sun, where he designed
and implemented the DTrace-based analytics facility found in the Sun Storage
7000 series of appliances-a facility that InfoWorld described as "stunning"
in a February 2009 review.

"As one of the world's foremost experts in system software and
application monitoring, Bryan will be one of the cornerstones of the team
we've been building here at Joyent," said Joyent CEO David Young. "His work
on DTrace and his insight into how applications run on the SmartOS will give
us a huge boost in the innovations we expect to bring to the table over the
next few years and beyond."

"The tech world is shifting, the definition of the operating system is
expanding and the data center is rapidly becoming the computer. Amidst a slew
of cloud companies, Joyent is one of the few focusing on innovation up and
down the stack to deliver a true cloud operating system," said Cantrill.
"Joyent has a deep sense of systems innovation and is well positioned to
develop the breakthroughs needed to deliver the full potential of cloud
computing."
