Abstract:Huge energy consumption of large-scale cloud data centers damages environments with excessive carbon emission. More and more data center operators are seeking to reduce carbon footprint via various types of renewable energy. However, the intermittent availability of renewable energy sources makes it quite challenging to cooperate with dynamically arriving workload.Meanwhile, the different natures (eg, price and carbon emission) of multiple energy sources also bring more challenges to achieve an optimal trade-o… Show more
“…In the third paper, the authors proposed a new finer‐grained model that can evaluate online the trade‐off between energy cost and carbon emission for operating large‐scale data centers on heterogeneous energy sources. They formulated this problem as a constraint stochastic optimization problem and proposed the Green‐Aware Online control Algorithm (GAOA), which makes an online decision relying only on the current system state and an efficient solution to achieve long‐term optimization by solving a mixed‐integer linear programming problem in each time slot.…”
