Some embodiments provide self-organizing retail resource load sharing systems comprising: a cluster of a set of node systems that receive resource requests; multiple different resource systems that implement predefined tasks consistent with the resource requests; wherein the node systems: access a valid ownership allocation configuration; confirm when a first node system is currently defined as the owner of a first resource system and authorizing activation of the corresponding first resource system when the resource request is intended for the first resource system; and cause the first node system to operate as a proxy and communicate the first resource request to a different embedded allocation application on a second node system that currently owns a second resource system when the first resource request is intended for the second resource system. Typically, the self-organizing load sharing is provided without external coordinators and reduced infrastructure, while providing high resource availability and reliability.
