A cloud consists of several elements such as clients,
datacenter and distributed servers. Scheduling is a critical
problem in Cloud computing, because a cloud provider has to
serve many users in Cloud computing system. So scheduling is
the major issue in establishing Cloud computing systems. The
main goal of scheduling is to maximize the resource utilization
i.e. energy consumption, power management and minimize
processing time of the tasks using migration. In this paper, we
will show how scheduling algorithms lead to optimization of the
Qos.

This paper presents common scheduling approaches in
computational cloud. Cloud Resources are heterogeneous
in nature, owned and managed by different organizations
with different allocation policies. So scheduling problem
must be handled in cloud computing. To perform better
cloud needs a good scheduling algorithm. Using
scheduling bandwidth of network can be utilized
efficiently and response time can be deducted. Scheduling
is the process to schedule data during transmission for
uploading and downloading. Scheduling schedule
application jobs and distribute load between machines to
avoid circumstances of hanging. If proper scheduling is
not achieved according to our requirement several errors
can occur and it will produce errors like a few numbers of
resources as their full capacity is not used and it is going
vain.
