An elementary module of a workflow of an audiovisual content distribution system, each content being received by a terminal in the form of a succession of segments, each segment being distributed to the terminal following transmission of a request by terminal and being obtained by an application of a workflow to a portion of content. The elementary module executes a processing of a predefined type and comprises: a variable plurality of processing units available for executing said processing; a scaling module, able to determine, using a first model, a number of processing units to be allocated for an implementation of a set of processing operations requested of said elementary module; and a load management module able to choose, using a second model, for each processing operation requested, one processing unit among processing units allocated by the scaling module for performing processing, each model being a neural network of the deep learning type.
