With competition heating up in open source clouds, an analysis of community participation among four major projects shows that Eucalyptus -- the oldest of those studied -- has the largest standing community, but OpenStack and CloudStack are gaining momentum in the developer community.
The dynamics of the open source cloud computing market are changing. Eucalyptus, which is a private cloud Infrastructure as a Service model, recently announced a partnership with Amazon Web Services to ensure interoperability between the two systems. Meanwhile, Citrix announced this week it would be migrating away from the OpenStack project and would give its CloudStack platform an Apache license, in effect creating a competing open source project to OpenStack.

Chinese blogger Qingye Jiang compares the open source communities of the three cloud deployment models plus OpenNebula, which is a data center virtualization project, and bases his findings on the mailing lists and public forum discussions of the projects.
Because Eucalyptus had an 18-month head start on OpenStack, the community has more users who have participated in the project. Eucalyptus began as a research project at the University of California, Santa Barbara in 2007 and became a commercial open-source project in January 2009. OpenStack began in July 2010 as a joint effort between Rackspace and NASA, and it has now grown to more than 150 companies.
