A study of task scheduling algorithms in cloud computing

Cloud computing is the provision of information technology (IT) services including servers, storage, databases, network management, etc. Like any new technology, cloud computing requires many improvements and the establishment of precise standards to avoid risks. Task scheduling can be seen as the management and handling of a set of tasks from their start to the step of execution. Scheduling is a negotiation mechanism between two objects, one representing the user (or the ap-plication) and the other the resources. In cloud computing, Task scheduling is of-ten considered as a real challenge to managers. In this paper, we will present some concepts and research papers that have proposed improvements or solutions to this challenge and we will compare some tasks scheduling algorithms in the CloudSim simulator.
