Information Technology Service Management with Cloud Computing Approach to Improve Administration System and Online Learning Performance
Abstract: This work discusses
the development of information technology service management using cloud
computing approach to improve the performance of administration system and
online learning at STMIK IBBI Medan, Indonesia. The network topology is modeled
and simulated for system administration and online learning. The same network
topology is developed in cloud computing using Amazon AWS architecture. The
model is designed and modeled using Riverbed Academic Edition Modeler to obtain
values of the parameters: delay, load, CPU utilization, and throughput. The
simu- lation results are the following. For network topology 1, without cloud
computing, the average delay is 54 ms,
load 110 000 bits/s, CPU utilization 1.1%, and throughput 440 bits/s.
With cloud computing,
the average delay
is 45 ms, load 2 800
bits/s, CPU utilization
0.03%, and throughput 540 bits/s.
For network topology 2, without cloud computing, the average delay is 39 ms, load 3 500 bits/s, CPU utilization 0.02%,
and throughput database server 1 400 bits/s. With cloud computing, the average
delay is 26 ms, load 5 400 bits/s, CPU utilization email server 0.0001%, FTP
server 0.001%, HTTP server 0.0002%, throughput email server 85 bits/s, FTP server 100 bits/sec, and HTTP server
95 bits/s. Thus,
the delay, the load, and the CPU
utilization decrease; but, the
throughput increases. Information technology service management with cloud
computing approach has better performance.
