A review of recent methods of task scheduling in cloud computing

Nowadays, cloud computing has come to the attention of big companies due to its high potential and flexibility and profitability. The approach followed in cloud computing services is to pay the costs for requested resources for an agreed period of time. In this system, the resource providers have to offer the best tradeoff between the requested resources and the amount of money users can pay, to be profitable for resource owners, in addition to customer satisfaction. Therefore, due to the massive volume of requests scheduling the users' requests is difficult and creating frameworks for scheduling is necessary. Scheduling algorithms attempt to allocate the tasks to the existing resources by considering the quality of services. In this paper, we review and compare various scheduling methods in the cloud computing environment.
