Competitive Study of Various Task-Scheduling Algorithm in Cloud Computing

Abstract

Cloud computing is a newly emerged field, and it develops very quickly. In cloud computing, the focus is on delivering computing resources such as hardware and software to the end-user directly, no matter when and where. These services are charged from clients on the per-use bases. There is a need for a decent scheduling mechanism that can help in the appropriate use of the assets. There are various resources available on the cloud and needs an efficient algorithm for better utilization of resources. One way is task scheduling. In cloud environment, there are numerous tasks which are running on the cloud; if two tasks try to approach a common resource, then there may be a chance of deadlock, which leads to system failure and performance degradation. For the better experience of cloud resources and to eradicate the aforementioned situations, there is a need of proper mapping between tasks and resources. In this paper, we comprehensively survey the various existing scheduling algorithms and these algorithms are compared on the basis of various performance metrics which are important to consider for the proper utilization of the resource.
