openstack tools?
Since when are " Chef, MongoDB, Docker, Cassandra and others" open stack tools? these are all stand alone applications/platforms. Maybe Openstack can use them but people have been using them without Openstack for years, and in some cases before Openstack probably even existed.
I wonder if EMC was just not getting much/any traction with ViPR so they decided to open source it instead. The concept of the product sounded pretty neat at first anyway.
