Cloud computing environment is meant to be consistently offering different services at requested time. Availability and waiting time plays very important role in this. By considering these two factors, scheduling of task with efficient algorithm in cloud environment is needed to be discovered and assign that task for execution. In this environment, virtual storage, network and servers are used so resource utilization and paid services should be timely available. In this paper, we will compare different task scheduling algorithms by considering some basic factors like makespan, request time, turnaround time etc.
