Improving The Performance For Failure-Aware Resource Provisioning In Cloud

Priyanka P, A Geetha, Biju Balakrishnan

Software fault tolerance is widely adopted to increase the overall system reliability in critical applications. System reliability can be improved by employing functionally equivalent components to tolerate component failures. The fault-tolerance strategies are calculating the failure probabilities of the fault-tolerant modules. The proposed policies take into account the workload model and the failure correlations to redirect users’ requests to the appropriate Cloud providers. Using real failure traces and a workload model, we evaluate the proposed resource provisioning policies to demonstrate their performance, cost as well as performance–cost efficiency.
