Research: Open Source IaaS Community Analysis

by

John Jiang has published some interesting data on user and developer community contributions of four of the Open Source Infrastructure as a Services (IaaS) solutions; OpenStack, OpenNebula, Eucalyptus and CloudStack. Jiang started this effort in Q4 2011 and has updated it every 3 months since.

Having insight in these kind of figures can give us an idea about which platforms have the most interaction and therefore are the most active from a development perspective.
