A method, system, program product and signal bearing medium embodiments of the present invention provide for deploying software modules for software application use in a computer system thereby reducing load time as well as memory requirements. Deployment of a plurality of software modules and associated deployment descriptors into a software module depository and creation of a deployment information repository from the associated deployment descriptors occurs. A name service is initialized with information from the deployment information repository and a requested software module identifier is then mapped to a respective enabler. Having mapped the requested software module to an enabler, the respective software module is enabled for the software application use. On-demand deployment in this manner saves start-up time as well as initial and ongoing memory allocation.
