It was observed that VMware maintains an old pool of appliances that sometimes link to the outer space. It even maintains two separate ways of representing the appliance characteristics. You can check http://www.vmware.com/appliances/directory/7 versus http://www.vmware.com/appliances/directory/786323 The estimated number of “old” VMware appliances is around 800. Knowing VMware had 1400+ appliances at the time of writing, the number of “recent” appliances drops down to ~600, which happens to match EC2’s share. To put things in perspective, “old” appliances are dated prior to 2006.
Windows is underrepresented in the appliance marketplaces. With a total of 53 Windows appliances found on EC2, the platform holds almost all of the 72 Windows appliances listed across all studied marketplaces. Redistribution and licensing must play an important part in those numbers. The Windows appliances found on Parallels and VMWare are sometimes beta or release candidiate version of the Windows OS.
On the Linux side, there are up to 14 different Linux distributions that appliances are running on: these are: Solaris, SlackWare, Mandriva, OpenBSD, Gentoo, RedHat, FreeBSD, Fedora, rPath, CentOS, Debian, SUSE and Ubuntu. Descriptions on the marketplaces crawled not being too accurate, it was sometimes impossible to label a VA more accurately than “Linux”. This was the case for EC2 appliances. Therefore the share of Ubuntu may be bigger than it seems. Ubuntu represents about 30% of all appliances on VMWare, 40% on VirtualBox, and 55% on Parallels. Should 30% of EC2 appliances be on Linux, the overall Ubuntu usage across marketplaces would jump by 6-7 points.
&quot;Others&quot; are unidentified OSs due to poor documentation
VirtualBox hosts 306 appliances.
There are no distinctions between Unix distributions on EC2
Parallels hosts 89 appliances
Categories are described on this page: http://www.vmware.com/appliances/categories.html
Over 677 appliances.
Over 1412 appliances.
Virtual Appliance Marketplace Stats
bers across m
“Marketplaces” are booming
EachVA-related vendor is at a different point of development
The idea is to compile data across leadingVA marketplaces
This represents about 2500 appliances
Raw data was captured via web crawlers on marketplaces respective
Metrics include operating system, submitter, appliance category
Data was cleansed at the appliance level to reflect exact appliance
