1. A software application comprising program code embodied in at least one computer-readable storage component, the software application comprising: a plurality of work order resources, wherein each work order resource defines an atomic operation for the software application and has a corresponding unique work order resource identifier; a construction service resource configured to process all interaction requests for the software application, wherein each interaction request includes a work order resource identifier, and wherein each interaction request is made as part of an activity being performed using the software application, wherein the construction service resource is configured to process each interaction request by: processing a representation of a work order resource corresponding to the work order resource identifier in the interaction request, wherein the processing includes constructing a set of deliverables as directed by the representation of the work order resource and context information for an activity corresponding to the requested interaction; and providing the set of deliverables in response to the interaction request; a system controller, wherein the system controller is configured to receive all interaction requests for the software application, and in response to receiving an interaction request, instantiate a container for processing the request, request a representation of the construction service resource for processing the interaction request, and provide the representation of the construction service resource the work order resource identifier included in the interaction request for use during execution of the representation of the construction service resource in the instantiated container; and a set of context resources, wherein the representation of the work order resource processing includes the construction service requesting a representation of a context resource referenced by the work order resource, receiving the representation of the context resource, and adjusting the work order resource processing based on the representation of the context resource.
