Similarly, there is nothing to prevent a cloud from being completely dispersed over wide area links, but such a cloud could suffer a performance disadvantage.

In addition to coordination with Cluster Managers, Figure 17 shows the Cloud Manager connected to the cloud’s Data Object Storage (DOS) repository. In actual implementations, the DOS could be distributed or put on different networks; however, the DOS services need to be available both to running virtual machines in the cloud and to systems from outside the cloud, and must be coordinated sufficiently with the Cloud Manager to keep track of valid consumer identities both to allow their administrative actions in the DOS and for billing.

A Cluster Manager receives resource allocation commands and queries from the Cloud Manager, and calculates whether part or all of a command can be satisfied using the resources of the computers in the cluster.
