There is no real call be the Linux Foundation to be bad
mouthing Solaris however I can agree with sentiment that it is a
slowly dieing OS. Linux has taken huge chunks out of the low end and
pretty much all the major ISVs have made Linux ports of their products
a priority so customers can choose which platform they want to roll
out on. I think both platforms offer broadly similar performance
although Sun probably do have a temporary advantage on storage with
DTrace is an interesting technology but I suspect IT managers with an
eye on the long game know Linux will catch up with something
eventually. Going with Solaris now and relying on ZFS and DTrace will
still make you dependant on what is essentially a proprietary OS and
exposing yourself to vendor lock-in is very much out of fashion these
days. Open Solaris still isn't quite the same as real Solaris,
certainly not as close as CentOS is to RHEL for example.
Sun still continue to make excellent hardware though and they offer an
interesting range of on-demand computing solutions. They happily
support Linux on their hardware as well and I suspect they are
resigned to the fact that hardware and services is where they are
going to have to make their money. Monetising the OS is a mugs game.
Shame of the Linux Foundation calling on Sun to GPL ZFS and DTrace
though. It's Sun's code and they can do what they like with it. The
call to GPL is a lot like saying "We know your dieing, we demand you
drink this cool-aid so it's easier for us to pick through you bones".
The Linux community should have the confidence to come up with it's
own innovative solutions to tracing and storage without trying to
think in corporate code from another OS.
