An infrastructure for on-demand service delivery receiving a request for a service to be performed from a service consumer with an information payload; decomposing requested service into essential or primitive functions; dynamically composing a sequence of a plurality of service elements corresponding to the essential or primitive functions to accomplish the service by employing a function call and return decomposition and recomposition paradigm; creating a control header and information payload, the control header encapsulating the sequence; repeatedly dispatching the control header to each service element in the sequence until all service elements have processed the information payload; and returning the processed information payload to the service consumer.
