Cloud Computing offers efficient computing with Pay-as-you-go models. It is now easy for consumer to start with- out need of initial setup, which saves a lot of infrastructure cost. As consumers are subscribing to the cloud, the load is increasing on the data centers, thus data centers are in need for more resources and more power. And all this process is increasing the carbon footprint and polluting environment. Now the time has come when we require efficiency in term of power. We really need to look for mechanism how the power can me be managed to be more efficient. This paper suggests the Green Architecture Framework and also suggests to use of Dynamic Voltage Frequency Scaling (DVFS) as per the load requirement which results in better energy efficiency
