The objective of this project is to set up intelligent spaces associated with business or industrial requests on a sovereign Cloud continuum. The solution chosen to create these intelligent spaces comes from a platform of digital twins whose first objective is to make the Cloud continuum on which it is embedded completely independent of the external environment. The digital twins, which form a representation of reality, should make it possible to optimise the performance, resilience, energy consumption and risks of the smart spaces linked to the services requested. This digital twin platform will be tested on two major use cases: the smart city and resource and risk control in the Cloud Continuum for the agile enterprise. These two use cases correspond to prototypes that will be developed in the project and then industrialised and extended and marketed by the partners.
