An OpenStack version in 2015, but whose OpenStack?
So the real questiion is, when EMC has its OpenStack version in 2015, which OpenStack will it use? Probably not plain vanilla OpenStack, which is hard to assemble. Probably not Red Hat's, which sells enterprise virtualization that competes with VMware's. It could be either VMware's OpenStack, which is less open than some versions because it runs the ESX Server hypervisor instead of KVM. Or it could be Cloudscaling's, whose Open Cloud System is a pre-integrated version of OpenStack with many configuration "opinions" included, such as Amazon APIs alongside OpenStack ones. EMC just bought Cloudscaling.
