ABSTRACT
Cloud Computing is a set of resources of which users’ requests on cloud services are
increasing on a day-to-day basis, and for better performance it should be balanced such
that all the requests should have minimum response time. Therefore, Load Balancing
is required and it is one of the major Issues in Cloud Computing. An essential task for
any cloud provider is task scheduling, wherein tasks are assigned to computing
resources within the cloud system by a broker. There is a lot of load balancing
algorithm implemented in cloud computing till today. The aim of this thesis is to test
the performance of some algorithms, namely Least-connection, Shortest Remaining
Time and Shortest Job First, in order to know which of them do better when there are
large cloudlets or when there are more VM, as well as when the CPU is higher or
lower. We successfully simulated the various algorithm using Cloudsim 3.0.3 and the
end-result shows that Least Connection Algorithm perform best when there are less
cloudlets with average turn-around time of 7.6 and average waiting time of 3.1 when
there are less cloudlets (tasks) in the system while in lower CPU, the result shows that
Shortest Remaining Time algorithm perform better with average turn-around time of
5.8 and average waiting time of 1.4. Also, the result shows that Least Connection
algorithm perform better than others with average turn-around time of 5.0 and average
waiting time of 8.0 when the system has less VM’s and Shortest Remaining Time
Algorithm perform best when there are more cloudlets of about 20 with average turn around time of 30.08 and average waiting time of 24.31 and there is no algorithm that
is considered to be the best because different algorithm does better than others at
different conditions/situations.
