Dynamic Topology Transitions In A Content Delivery Framework

A first group is defined from an arbitrary set of nodes comprising service instances. Each node in the first group assumes one or more responsibilities in processing a request across the first group. A second group is defined from an arbitrary set of nodes. Each node in the second group assumes one or more discrete responsibilities in processing a request across the second group. The second group has a topology distinct from that of the first group. Request processing is transitioned from the first group to the second group based on a responsibility adaptation policy.
