Various implementations disclosed herein enable improved allocation of fog node resources, which supports performance driven partitioning of competing client applications. In various implementations, methods are performed by a fog orchestrator configured to determine allocations of fog resources for competing client applications and partition the competing client applications based on the fog resource allocations. Methods include receiving reservation priority values (RPVs) associated with a plurality of client applications competing for a contested fog node resource, transmitting, to a subset of client devices, a request to provide updated RPVs, and awarding the contested fog node resource to one of the plurality of client applications based on the received RPVs and any updated RPVs. In various implementations, methods also include determining, for each of the plurality of client applications, a respective mapping for a respective plurality of separable components of the client application based on the awarded contested fog node resource.
