Ian Howells, Doctor of Marketing over at Alfresco, has published results of a survey of their users to come up with a barometer of open source. While the sample is from Alfresco's own users (and perhaps a bit skewed), it's an interesting snapshot on how open source is being used in the mainstream. In particular, it's clear that open source co-exists with closed source in many organizations.

While the sample is from Alfresco’s own users (and perhaps a bit skewed), it’s an interesting snapshot on how open source is being used in the mainstream. In particular, it’s clear that open source co-exists with closed source in many organizations. A few of the highlights: -Users evaluated use of Alfresco on Windows as much as on Linux, though Windows (42%) is used more for evaluation and Linux (52%) for deployment. -Tomcat (72%) and JBoss (20%) were the most widely used application servers, with greater adoption than closed source app servers from IBM, BEA and Sun. -MySQL was the most widely used database, at over 60%, with Oracle (14%), SQL Server (12%) and Postgres (8%) also used. -Firefox was the most widely used browser, with browser usage was higher than portal usage in general. Most interesting, Alfresco will update the survey every six months, thereby going beyond just a snapshot to provide insight into adoption trends over time.
