Comparison between Openstack and CloudStack

	OpenStack www.openstack.org	CloudStack www.cloudstack.org
Overall Grading Based on fit-to-purpose in Newegg	****	******
Executive Summary	Although Openstack has more than 200 vendors in the committee but this make the development lack of direction. A lot of the plugins could not fully integrate with others. Also, Openstack lacks the maturity to put into the corporate production, they are still in the rapid development path. Version Change so rapidly and compatibility issue between versions. Cloudstack is a commercial solution before, it has more maturity to go into production than Openstack. Also it keep the compatibility between versions. it also support some critical features required by Newegg e.g. easier to install, mature GUI, Charge back, Usage metering, Resource Limit, capable of Supporting Newegg existitng virtualization platform e.g. vSphere seamlessly
Evaluator Personal Experience	I installed the Openstack Diablo before but when we upgrade to Essex, I found that the configuration is fully compatible with the Essex. The software is upgrading too fast and developed by too many different vendors with each of them of different objective. The platform seems to be not mature enough for production environment
