WORKFLOW SCHEDULING STRATEGIES FOR ACHIEVING FAULT TOLERANCE IN CLOUD: REVIEW ARTICLE

Abstract

Cloud computing is increasingly used amidst researchers for scientific workflows to perform high throughput computing and data analysis. cloud are realizing the vision of utility by delivering computing resources as services. There are many workflow scheduling algorithms focuses on makespan time, cost and reliability etc. Numerous research studies have investigated fault-tolerant aspect
of the workflow management system in different distributed systems. In this study, we analyze these efforts and provide an in-depth taxonomy of them. We present the ontology of faults and fault-tolerant techniques then position the existing workflow management systems with respect to the taxonomies and the techniques.
