The Research to Enhance the Dependability of Cloud Service

This paper combines with the self-healing and AOP technology, and proposes a framework to enhance the dependability of cloud services.We consider enhancing the dependability from the logical layer of cloud service and implement "pluggable" way to configure the dependable strategies dynamically.Using fault injection method for simulation, the result shows that this framework can reduce the possibility of cloud service failure effectively and enhances the dependability of the cloud service.
