Distinct clusters of servers: Cluster "Tokyo" consisting of node A, B, C Cluster "Stockholm" consisting of node D, E, F Cluster "New York" consisting of node G, H, I All with the same CIB XML document. Using tickets, resources can then be moved from one cluster to the other, or cloned across multiple clusters. A cluster of clusters, if you will.
