Rackspace announced the The Rackspace Cloud: Private Edition on Monday. The Private Edition makes available OpenStack software to enterprises seeking to deploy a private cloud. The offering contains three components: (1) OpenStack operating system software; (2) reference architecture specified by Rackspace and (3) managed services for setup and support in collaboration with ‘Certified Deployment Partners’ such as CloudTP, MomentumSI and TeamSun. Rackspace’s announcement of The Rackspace Cloud: Private Edition represents yet another step in the evolution of OpenStack and open source cloud computing. Rackspace, one of the founders of OpenStack, will now provide support for OpenStack deployments outside of its own data centers by leveraging a managed services model.
