SERVICE LINKAGE DEVICE, PROGRAM, SERVICE LINKAGE METHOD, AND SERVICE PROVISION SYSTEM

摘要

A processing load on service is distributed to improve the availability of linkage service even if the details of the processing of the linkage service are unknown. A service dynamic linkage device (110) sequentially selects pieces of web service which can be executed on the basis of dependence relationship information having identified a web server which should have already been executed among pieces of web service included in a scenario, the execution of which has been requested from a user-side communication terminal (140), and repeatedly performs processing to be executed until there are no pieces of web service included in the scenario.
