The invention relates to a system and a method for generating an aggregated data accessible at an aggregated interface (10) of a user client (2) within the framework of unified governance of a plurality of intensive computing solutions (70), said generation method including the steps of: Receiving (210), by a proxy microservice (20), access command information of a user client (2), contained in a message coming from an aggregated interface (10), Determining (220) data accessible to the user client (2) based at least partly on the access command information, Determining (230) data to be aggregated from the accessible data determined by each of the computing microservices (50, 51, 52, 53), Generating (240) an aggregated data from the data to be aggregated from the accessible data, and Transmitting (250) the aggregated data, by the proxy microservice (20), to the aggregated interface of the user client (10).
