Many people ask me what is the realtionship between cloudstack, Citrix and Cloud.com.
This is how Citrix explain it themselves:
Citrix Systems today announced a new edition of CloudStack™, which will feature enhanced support for both the VMware vSphere and Oracle VM hypervisors, enabling VMware and Oracle customers to manage their virtualized servers as a highly available, scalable cloud computing environment. Citrix CloudStack is not just a traditional enterprise server virtualization platform with cloud management layered on top, it is a production-ready, free and open source cloud infrastructure platform that helps providers of all types deploy and manage simple, cost-effective cloud services that are scalable, secure, and open by design. The new release is based on the same CloudStack solution that has been used by some of the world’s largest and most successful public clouds to roll out new cloud services up to 50 times faster and at one-fifth the cost of alternative solutions(1). This is the first release of the product since Citrix acquired Cloud.com in July.
