Delivering cloud services with QoS requirements: Business opportunities, architectural solutions and energy-saving aspects
We introduced, the description of a new architectural approach based on the gateway paradigm for the QoS-aware cloud broker on the Hybrid Cloud. We discussed the use of energy saving policies and evaluate it by an energy metric. We incorporated a preemption mechanism able to guarantee the whole satisfaction of specific high priority users. We evaluated system usage through the utilization metric, and related it with respect others metrics. We went in more details, in the analysis of simulated scheduling scenarios and behaviors with respect to the new policies and metrics.
