Abstract: Techniques for determining one or more replication paths for resources in different failure domains, while maintaining a target resiliency level, are disclosed. A replication path is a sequence of at least a subset of the set of resources. Based on the sequence, a resource is selected for replicating at least a portion of the resource consumers corresponding to each of the subset of resources. A replication path may be determined by adding a resource to the replication path and/or replacing one resource with another resource to modify the replication path. The modified replication path maintains the target resiliency level if the modified replication path does not include any loop of a length less than or equal to the target resiliency level.
