Nerval's Lobster writes "At this year's Dell World conference, Dell announced that its new private cloud will be based on the open-source OpenStack, an Infrastructure-as-a-Service developed by Rackspace and NASA that launched in 2010. Dell released a statement supporting the open nature of OpenStack: 'While Dell will continue to offer outstanding overall solutions for any type of cloud that customers want to run, the company believes the open and compatible nature of OpenStack allows customers to take advantage of hybrid capabilities to move workloads between private and public clouds.' Michael Dell did not disclose the reasoning behind the decision. Back in 2011, his company announced that VMware technology would provide the foundation for its first public cloud. VMware also sits behind the Dell Cloud Dedicated Service, which delivers managed private cloud IaaS."
