Cloud Suite also uses OpenStack, but as a substrate managed through Red Hat's CloudForms software. On top of that is the part users will deal with most directly: Red Hat's OpenShift PaaS for managing containerized applications in Docker. (OpenShift got high marks from InfoWorld's Martin Heller for being "robust, easy-to-use, and highly scalable.")
CloudForms treats OpenStack as one of many possible cloud layers that can be abstracted away. To that end, the apps deployed on OpenShift can run in multiple places -- local and remote OpenStack clouds, Azure clouds, and so on. This part of Red Hat's strategy for hybrid cloud echoes Google's ambitions, in that it allows the user to work with open source software and open standards to deploy apps to both local and remote clouds.
OpenStack was regarded as the original method to pull that off. While Red Hat hasn't abandoned OpenStack, its focus remains narrow. Cloud Suite, due to its flexibility and emphasis on applications rather than infrastructure, seems likely to draw a broader crowd.
