Finally, the architecture exposes in the Cloud another useful service that provides statistical information about the busyness of the museum. Indeed, by exploiting the localization information, this service always knows how many visitors are moving in the museum and where they are. Therefore, this service can be used by external users to know in advance the length of queues in specific areas of the museum or which are the most admired artworks. Moreover, the information provided by this service could also be exploited by the museum supervisors to schedule partial maintenance works or to reorganize the internal spaces.
