A method, comprising: receiving a first service request from a network device, wherein the first service request has a first preset format, the first service request is used to request to invoke a meta service and the first service request comprises a parameter that matches metadata of the meta service, wherein the meta service is a service provided for a user; wherein invoking the meta service comprises: invoking a cloud service corresponding to the meta service, after the corresponding cloud service is invoked obtaining an invocation result, integrating the invocation result, and after integration using the integrated invocation result as a service response for invoking the meta service; translating the first service request into a second service request based on a first packet structure, wherein the first packet structure is obtained by matching the parameter with metadata of a cloud service, wherein the second service request has a second preset format which supports invoking the cloud service in various cloud environments and the various cloud environments comprise at least two cloud services; and sending the second service request to at least one cloud service device in the various cloud environments; wherein the translating of the first service request further comprises: translating the first service request into a second service request according to a mapping relationship between the first preset format and the second preset format; and wherein the mapping relationship is a relationship between first information from the network device and second information from the at least two cloud services; wherein the first information comprises a first data from the network device, and the second information comprises a second data which is processed by the applications in the at least two cloud services. receiving a first service request from a network device, wherein the first service request has a first preset format, the first service request is used to request to invoke a meta service and the first service request comprises a parameter that matches metadata of the meta service, wherein the meta service is a service provided for a user; wherein invoking the meta service comprises: invoking a cloud service corresponding to the meta service, after the corresponding cloud service is invoked obtaining an invocation result, integrating the invocation result, and after integration using the integrated invocation result as a service response for invoking the meta service; translating the first service request into a second service request based on a first packet structure, wherein the first packet structure is obtained by matching the parameter with metadata of a cloud service, wherein the second service request has a second preset format which supports invoking the cloud service in various cloud environments and the various cloud environments comprise at least two cloud services; and sending the second service request to at least one cloud service device in the various cloud environments; wherein the translating of the first service request further comprises: translating the first service request into a second service request according to a mapping relationship between the first preset format and the second preset format; and wherein the mapping relationship is a relationship between first information from the network device and second information from the at least two cloud services; wherein the first information comprises a first data from the network device, and the second information comprises a second data which is processed by the applications in the at least two cloud services. translating the first service request into a second service request according to a mapping relationship between the first preset format and the second preset format; and wherein the mapping relationship is a relationship between first information from the network device and second information from the at least two cloud services; wherein the first information comprises a first data from the network device, and the second information comprises a second data which is processed by the applications in the at least two cloud services.
