An energy sentient service brokering strategy in cloud computing

With the development of cloud computing, on-demand resource provision has become a key feature of it. However, most cloud service providers have their own interface type, energy consumption level and other service features. A service broker in cloud computing plays an intermediate role between providers and users. It is designed to find out the suitable services from the various service providers and meet the user's requests. Maximizing the energy efficiency is not only good for the environment protection but also could benefit the providers. This paper proposed an energy sentient service brokering strategy, which try to find a suitable trade-off between energy consumption and user's satisfaction. Simulation results show that our proposed strategy could effectively reduce the energy consumption and maintain user's satisfaction in a reasonable level at the same time.
