In a content delivery framework including a network with multiple delivery service endpoints running on devices, the multiple service endpoints forming a plurality of sub-clusters, a group is defined from a set of nodes comprising delivery service instances across the devices of the plurality of sub-clusters. Each node in the group assumes one or more discrete responsibilities involved in processing of a request across the group, the discrete responsibilities including being fill-responsible. A fill-responsible node is selected from the group to be responsible for processing a request made at a node of the group, the request relating to a particular resource. Selection of the fill-responsible node is based on the particular resource, and the fill-responsible node is selected from a set of one or more nodes in the group that are fill-responsible for the particular resource, the set being defined based on a policy associated with the particular resource.
