Abstract

A method commences upon accessing a set of data items that describe computing nodes to be organized into failure-tolerant configuration. The failure-tolerant configuration is characterized by system availability characteristics such as a replication factor and such as a hierarchical distribution of computing nodes. Characteristics of the topology include boundaries that define two or more hierarchically-related availability domain levels. Computing nodes are situated within these boundaries. Instances of a target hierarchical availability domain level are sorted, and instances of a hierarchically lower availability domain level are also sorted to form a multi-level sort order of computing nodes. Computing entities are mapped onto the computing nodes by observing the multi-level sort order.
