Alfresco announced the availability of its second global survey of trends in the use of open source software in the enterprise. The Alfresco Open Source Barometer survey was conducted throughout 2007 using opt-in data provided by Alfresco's 35,000 community members and shows deployments of Ubuntu and Red Hat Enterprise Linux with a market share of 24% and 21% respectively.

Alfresco's open source barometer asked users about their preferences in operating systems, application servers, databases, browsers and portals to capture the latest information about how companies evaluate and deploy open source and proprietary software stacks in the enterprise. Survey data collected during July to December 2007 included new questions about which office suite and virtualization products community members used, what their content management requirements were and what environments they trialed Alfresco in.

"Alfresco's open source barometer addresses questions of how open source is used, who the leading vendors are and differences from evaluation to deployment, by geography and the trends overtime," commented Dr Ian Howells, CMO, Alfresco Software. "Our goal is to provide a leading indicator of enterprise open source adoption trends, examining how and where open source is used in the Global 5000 enterprise stack."
