Automatic Diagnosis for Composite Web Service in Cloud Computing
Cloud computing is becoming a popular and important platform for web service applications.With the advent of more and more service resources in cloud,it is a crucial challenge to build an effective diagnostic mechanism.To improve the diagnosis capability for composite web service,we propose an automatic diagnostic framework and a hybrid diagnosis method for diagnosing the faulty activities.Our diagnostic framework can improve the scalability of diagnostic system and add the diagnostic capability of diagnosis service by decoupling the diagnostic service components.Our diagnosis method identifies the differences between successful and failed executions for finding the incorrect activities of the composite service and provides faulty causes by considering the structured activities in the process of diagnosis.Experimental results show that our method is effectivo to the composite web service in the fault diagnosis.
