Towards workflow scheduling in cloud computing: A comprehensive analysis

Workflow scheduling is one of the prominent issues in cloud computing which is aimed at complete execution of workflows by considering their QoS requirements such as deadline and budget constraints. Numerous state of the art workflow scheduling schemes have been proposed in the literature for scheduling simple and scientific workflows in the cloud computing and this paper presents a comprehensive survey and analysis of these schemes. It illuminates the objectives of scheduling schemes in the cloud computing and provides a classification of the proposed schemes based on the type of scheduling algorithm applied in each scheme. Beside, each scheme is illustrated and a complete comparison of them is presented to highlight their objectives, properties and limitations. Finally, the concluding remarks and future research directions are provided.
