Resource constraints for a group of individual application products to be configured for shared resource usage of at least one shared resource within a single operating system instance are analyzed by a resource allocation module. An individual resource allocation for each of the group of individual application products is determined based upon the analyzed resource constraints for the group of individual application products. The determined individual resource allocation for each of the group of individual application products is implemented within the single operating system instance using local inter-product message communication bindings by the single operating system instance.
