VMware Throws In Towel On EMC-Virtustream In a move that partners said created uncertainty and confusion in the virtualization market, VMware threw in the towel this week on its EMC-Virtustream cloud joint venture. VMware had agreed to be part of the Virtustream Cloud Business two months ago. The joint venture would have been jointly owned by EMC and VMware and would have created a "true cloud integration" between cloud and virtualized environments, wrapping together Virtustream, vCloud Air hybrid cloud and other VMware cloud management offerings. VMware had predicted it could be profitable multibillion-dollar business over the next several years. Partners said the sudden reversal left them feeling confused, as they had already started building cloud services pipelines around the venture.
