To be perfectly honest, it is with some trepidation that I have started
this blog. While I marvel at this new opportunity to be a part of
these conversations with the various Sun communities, I worry that it
will be difficult time-wise to stay involved. Perhaps I also share
some of the feelings expressed by
when he says that that it
feels like talking into thin air.
In any case, this is a wonderful opportunity for all of us to hear from
about what concerns you have and how we can make Solaris
nexus of innovation
as well as a way of solving your computing needs.
Briefly, I have been working at Sun on Solaris for a little over eight
years now, initially in the networking group responsible for the TCP/IP
stack and related technologies and for the past couple of years, in the
area of server virtualization and resource management working inside a
and a number of others in introducing Zones into Solaris.
Zones provide a new operating system abstraction for partitioning
systems so that multiple applications can be run in isolation from one
another, while perhaps being administered by different privileged
users. It borrows in a number of ways from the concepts introduced by
but extends it to be full integrated with the features that Solaris
offers. In my opinion, the most exciting point of integration is with
Solaris Resource Management
framework which was introduced in Solaris 8 and greatly enhanced in
Solaris 9 and 10 because combined they provide the necessary
characteristics to fully isolate applications and workloads from one
another. Together, these two technologies form the basis of N1 Grid
Containers which are supported on all system that Solaris supports,
from single-processor x86 laptops, to large, multi-processor servers.
For a brief but semi-technical overview of Solaris Zones, a good
starting point is the
we presented at a work-in-progress session at the recent
USENIX VM '04
conference. For more information in general about Zones, the
Zones BigAdmin site
provides a great deal of information including a pointer to the latest
documentation on these technologies and an active discussion forum.
And to repeat a popular refrain, we encourage you to not just read
about Zones and the other new functionality in Solaris 10, but to
experience it yourself by downloading it from the
Software Express for Solaris site.
