Abstract: Aiming at the comprehensive application of massive data storage and energy saving algorithm of data center in cloud computing, the effective solution of the problem of data energy consumption is focused on. The generation of data energy consumption not only increases the amount of carbon dioxide emissions, but also brings about serious environmental problems. In combition with the definition characteristics of cloud computing, the high energy consumption of the data in cloud computing system is studied in this paper. By analyzing the classification of data energy saving algorithms, the DVFS data energy saving algorithm, the virtual energy saving algorithm and other algorithms are analyzed. A detailed summary for the data management process of energy consumption in cloud computing system is made.
Keywords: cloud computing system; data energy saving algorithm; energy saving; environmental protection
現(xiàn)階段,云計算這種新興計算機模式在用戶即用即付行為方式中,為動態(tài)性靈活的架構(gòu)和服務(wù)提供了便利,再結(jié)合Internet中的IT能力給用戶提供服務(wù)形式,用戶可以直接結(jié)合Internet獲取服務(wù)。一般而言,云計算不僅僅具有著較大的規(guī)模和虛擬化特點,同時也具有著可靠的數(shù)據(jù)存儲和共享性,在計算機平臺的推廣應(yīng)用階段,各種計算機基礎(chǔ)設(shè)施中同樣也得到了廣泛的應(yīng)用[1]。如何做好云計算系統(tǒng)數(shù)據(jù)節(jié)能算法的應(yīng)用始終是計算機行業(yè)領(lǐng)域關(guān)注的焦點。因此本文對基于云計算系統(tǒng)的數(shù)據(jù)節(jié)能算法的探討有一定的現(xiàn)實意義。
