I think OpenStack, CloudFoundry, ..., are still not what I have in mind, as this solutions are more designed at scale, that is, if you want to provide a PaaS service to third parties or if you are a very large organization. IMHO the missing piece here is something that you can install in just one or a few nodes to start providing easy-to-setup and monitored services, with proven configurations and setups and so forth.
