Citrix goes all in for open-source XenServer cloud

Citrix has announced that all of its XenServer 6.2 platform will be open-source software. Citrix isn’t making these open-source moves because Xen isn’t popular. Far from it.

Xen is the foundation of both the Amazon Web Services (AWS) cloud and Rackspace’s OpenStack-based cloud. XenServer has customers.

So why commit everything, à la Red Hat, to open source?
