Keystone federated security

Hybrid clouds are increasingly becoming important in cloud computing. We see a rapid raise in the demand for a secure infrastructure that would enable sharing of computing resources between multiple hybrid cloud deployments to facilitate accommodation of situations where the demand outstrips supply, load balancing, and other such infrastructure constraints. From the end user perspective, this would also mean that the end users can host applications with their choice of federated cloud provider, as opposed to choosing from a host of global cloud providers on the market. The following paper describes a federated infrastructure for hybrid clouds, in particular, Openstack.
