Problem Based Learning on Cloud Economics Analysis Using Open Source Simulation

Abstract

The paper reports the applicablity of open source simulation software called GreenCloud to assist a novel Problem Based Learning in a laboratory environment. The actual case of Indonesia government plan to deploy cloud based data center infrastructure was picked up as the actual case. In such case, cloud economics analysis is required along with technical one. An open source software called GreenCloud is suitebale to perform the simulation and analysis of cloud computing from economics perspective. It was applied into three models of cloud architecture namely Two-Tier, Three-Tier and Three-Tier High Speed and then analyzed in terms of their energy consumptions based on three options of cloud economics scheme, namely i) non energy savings, ii) Dynamics Voltage and Frequency Scaling (DVFS) and iii) Dynamics Shutdown (DNS).
