Abstract

In this short paper we make a simple extension of our previous work on efficient distributed file system (EDFS) for cloud computing to make it more energy efficient. Our GreenEDFS scheme uses the EDFS mechanism to constantly monitor the cloud resources and then moves computation, communication and storage loads from less loaded (under utilized) areas of the cloud to other less loaded (under utilized) areas of the cloud by ensuring full resource utilization and avoiding unnecessary over-utilizations (buffers, delays and losses). GreenEDFS moves load (computation, communication, storage) from one area of the cloud to the other every greening periods which can be user defined or obtained and triggered using some clever ways, for instance when the load in a given cloud node gets below a certain threshold. The movement of traffic in the cloud (greening) can be done both at a local cloud rack level or global by going all the way up in the cloud structure the same way EDFS performs the resource allocation. The scheme dynamically expands and contracts the cloud size based on the demands and constant monitoring provided by EDFS. This can result in a clever significant energy saving mechanism without compromising performance. We are working to demonstrate the energy saving of our scheme using simulation and real testbeds.
