Red Hat Cloud Infrastructure. It lays a solid foundation for you to build and manage private cloud Infrastructure-as-a-Service (IaaS)—using truly open, interoperable, easy-to-manage Red Hat products that won’t lock you in.
Red Hat Cloud Infrastructure is built on the trusted Red Hat Enterprise Linux platform and Red Hat Enterprise Virtualization. Using lower-cost open-virtualization technologies lets you increase your private-cloud environment's capacity and combine it with the proprietary virtualization capacity you already have.
