I think that was done specifically to mimic the 2009 eclipse survey. Why
eclipse would want to lump them together in a survey however is beyond me. Might
as well lump all the Debian and Ubuntu derivatives together too if you are going
to do that.
Anyways, general problems with accounting for skew in opt-in usage
information aside (you'd be amazed at what political pollsters do to for
correction factors when doing sample polling).
Two main questions I have about this graph:
Does this graph include both the no-cost community edition product and the
for-pay Enterprise products? Can the OS breakdown be generated for the community
and enterprise products separately?
Does this include the pre-built appliance images (both community and
enterprise)? The blog specifically mentions the Suse based vm image and the
pre-built ec2 AMI (is that an Ubuntu based image?) for GWOS. If those pre-built
images are included in the stats how are those accounted for? Are the 8% listed
as Suse the prebuilt vm image? Is that 14% listed as Ubuntu a GWOS prebuilt EC2
AMI? Looking at the available literature at the groundworks website the
Community Edition vmware vm is based on CentOS. So is the 40% CentOS the
community edition virtual machine running under vmware? prebuilt appliance
images really complicate how you account for OS usage. I would have liked to
see virtual machines broken out to get an idea of how many people are running
appliances under vmware as a windows or linux host, versus xen based EC2.
