Fecha de publicación: 27/07/2021 Fuente: Wipo "BigData" The invention provides a cloud computing service system based on big data, and relates to the technical field of data service. The cloud computing service system based on the big data comprises a cloud service terminal, a data acquisition unit, a monitoring unit and a data monitoring unit, the cloud service terminal comprises a communication module B used for information transmission, a storage module used for data storage, a temporary storage module used as emergency standby, an encryption module used for confidentiality management, an identity checking module used for identity verification and a retention module used for deleting data retention. The monitoring unit comprises a temperature sensor for temperature detection, a processor for information processing and a radiator for accelerating cooling. Through the design of the data monitoring unit, during big data processing, adjustment can be made according to the processing amount of data, when the data is huge, the temporary storage module is matched to be started to relieve the pressure of the cloud service terminal, and the situation of paralysis caused by loads can be avoided to a certain extent.
