The invention provides a cloud service management system. The cloud service management system runs on a cloud platform and can interact with a virtual resource operating system, wherein the cloud platform provides a plurality of cloud service platform interfaces for being invoked by the cloud service management system; the virtual resource operating system provides a user interaction window for a user to send a service request. The cloud service management system comprises a cloud-cloud interface layer, a command control module and an interface adaption management unit, wherein the cloud-cloud interface layer is packaged with a plurality of cloud-cloud interfaces unified with the virtual resource operating system; the service request comprises one of the cloud-cloud interfaces; the command control module is used for receiving the cloud service request, and analyzing the cloud service request to generate a cloud platform operating command; the interface adaption management unit is used for acquiring an adaptive cloud service platform interface according to the cloud platform operating command, and invoking the cloud service platform interface. The invention further provides a cloud-cloud management system. The cloud-cloud management system comprises the cloud service management system and the virtual resource operating system.
