The folding of private cloud vendor Nebula a couple of weeks ago seemed to suggestthat OpenStack is becoming the exclusive domain of large, established open source companies that can package and integrate the cloud-computing platform for easy deployment. But that may not be the whole story, if RDO, a community-based OpenStack distribution, succeeds.RDO is a version of OpenStack designed for use on CentOS, a Linux distribution based onRed Hat Enterprise Linux. Actually, "based on" is a bit of a stretch, because CentOS is basically the RHEL source code recompiled by third parties—which is totally legal and kosher with Red Hat, of course, since the source is open. The only difference between CentOS and RHEL is that the former comes with no enterprise-class support or ecosystem integration.Accordingly, RDO also lacks enterprise support services. For those, you'd need an option like RHEL OpenStack Platform, or one of the various other commercial OpenStack distributions from vendors such as Canonical, Hewlett-Packard (HPQ) or VMware(VMW).
