Abstract:
The aim of Green Cloud Computing is to achieve a balance between resource consumption and quality of service. In order to achieve this objective and to maintain the flexibility of the Cloud, dynamic provisioning and allocation strategies are needed to manage the internal settings of the Cloud, addressing oscillatory peaks of workload. In this context, we propose strategies to optimize the use of the Cloud resources while maintaining the service availability. This work introduces two hybrid strategies based on a distributed system management model; it describes the base strategies, operation principles, it validates and analyzes them, and it presents the results. In order to validate our proposed strategies, we extended CloudSim to simulate our strategies. We achieved a consumption reduction up to 87% comparing Standard Clouds with Green Clouds, up to 52% comparing the proposed strategy with other Green Cloud Strategy, and 13% less consumption using Dynamic Voltage and Frequency Scaling (DVFS) in hybrid provisioning strategy.
