Dynamically updating templated applications

Embodiments of the present invention address deficiencies of the art in respect to templated application deployment, and provide a novel and non-obvious method, system and computer program product for dynamically updating templated applications. In one embodiment of the invention, a templated application deployment data processing system can include an application container configured to host templated application instances defined by one or more templates. The system also can include application deployment logic including program code enabled to deploy the templated application instances into the application container responsive to the templates. Finally, the system can include a listener architecture coupled to the application deployment logic and configured to notify the application deployment logic of changes to the templates for the application instances.
