Abstract: An intelligent tracking system includes a processor and a storage device. The processor is used to access a service content analysis module, a remote sensing payload analysis module, a span module, and a remote sensing storage module to execute the service content analysis module, the remote sensing payload analysis module, the span module, and the remote sensing storage module. The processor executes the following operations. The service content analysis module analyzes service data to obtain a general content and a remote sensing payload. The remote sensing payload analysis module analyzes the remote sensing payload to obtain customized data. The span module adds at least one log to the service data to generate span data. The remote sensing storage module stores the span data, the general content, the remote sensing payload, and the customized data in a database to form tracking data.

Abstract: An intelligent selection method is provided to determine the communication mode when the first service calls the second service in the information system platform to execute a service with multiple tasks. The aforementioned method includes calculating the unfinished workload of the first service's previous call to the second service, and calculating the task-completion time of the most recent work completed by the second service. The aforementioned method includes selecting whether to use the first strategy or the second strategy to communicate when the first service calls the second service, according to the unfinished workload and the completion time. Finally, the aforementioned method includes notifying the first service of the selection result.

Abstract: A cloud platform comprises a first tenant server, a second tenant server, a first tenant database, a second tenant database, and a cloud data exchanging system. The first tenant server and the second tenant server are coupled to the first client and the second client respectively. The first tenant database and the second tenant database are respectively coupled to the first tenant server and the second tenant server via the cloud data exchanging system. The cloud data exchanging system, after receiving a query request from the second client via the second tenant server, determines whether the data relation table has any data links belonging to the second client. If so, the cloud data exchanging system finds database information from a database connection table according to the data link and enters the first tenant database according to the database information.
