Methods and system are disclosed that instantiate an on demand functionality for a layer in a multilayered system. In one aspect, a framework integrated with the multilayered system may receive a request to create a root function. The root function may be associated with common functionalities or specific functionalities. Based on parameters associated with the layers and attributes associated with data flow paths between the layers, a layer to deploy the root function may be determined. Upon deploying the root function, sub functions may be created in the determined layer by the framework. The sub functions may be configured common functionalities or specific functionalities by the framework. A function model including the root function and the sub functions may be generated. The function model may be instantiated to provide an on demand functionality or an on demand application.
