摘 要:云計算平臺虛擬化技術(shù)的出現(xiàn)使得各類應(yīng)用資源的按需動態(tài)配置成為可能,大大提高了資源的利用率。共享資源池的出現(xiàn),使云環(huán)境中服務(wù)器的數(shù)量得到減少,從而增加了云服務(wù)提供商的收益。負載均衡可以實現(xiàn)物理資源和虛擬資源消耗的匹配。通過云計算資源,人們可以采用MOGA-D算法,將多目標優(yōu)化調(diào)度方法應(yīng)用在移動端子系統(tǒng)中,實現(xiàn)最終的資源調(diào)度。對比實驗結(jié)果表明,與傳統(tǒng)方法相比,該方法具有更加突出的有效性。

Abstract: TThe advent of cloud computing platform virtualization technology makes it possible to dynamically configure various application resources on demand, which greatly improves the utilization rate of resources. The emergence of shared resource pools has reduced the number of servers in the cloud environment, thereby increasing the revenue of cloud service providers. Load balancing can match the consumption of physical resources and virtual resources. Through cloud computing resources, people can use the MOGA-D algorithm to apply the multi-objective optimized scheduling method to mobile terminal systems to achieve the ultimate resource scheduling. The comparison test results show that the method has more prominent effectiveness than the traditional method.
Keywords: mobile;cloud computing;multi-objective optimal scheduling
移動終端是指可以在移動中使用的計算機設(shè)備,它可以分為兩類,一類為模擬移動終端,如數(shù)字蜂窩電話和模擬蜂窩電話,另一類為數(shù)字移動終端。移動終端具有極強的便攜性,客戶端子系統(tǒng)主要由平板電腦、智能手機等手持移動設(shè)備組成,這些設(shè)備將代替服務(wù)器智能地發(fā)出請求,將所需要的分塊緩存或下載到本地運行,以滿足服務(wù)需求[1,2]。
1 云計算資源多目標優(yōu)化調(diào)度方法
采用云計算的方式,用戶就可以通過網(wǎng)絡(luò)將需要處理的數(shù)據(jù)發(fā)送到云計算終端的數(shù)據(jù)中心,由數(shù)據(jù)中心對數(shù)據(jù)進行處理,并及時將處理結(jié)果反饋給用戶,資源的使用率得到大幅提高,減少了所消耗的資源,這樣有助于“節(jié)能減排”[3-5]。目前,如何減少激活服務(wù)器的數(shù)量是云平臺節(jié)約型資源調(diào)度方法需要解決的問題,從而達到節(jié)能的目的,實現(xiàn)綠色計算。……
