【摘要】:為了保證響應(yīng)時(shí)間百分比SLA的同時(shí),最小化商用云中心資源配置成本,基于排隊(duì)理論提出了云中心模型,從經(jīng)濟(jì)角度分析云中心資源配置成本,并推導(dǎo)出云中心響應(yīng)時(shí)間百分比的數(shù)學(xué)表達(dá)式。給出了計(jì)算最小配置成本算法(MPCA),通過(guò)大量實(shí)驗(yàn)分析了負(fù)載流量、響應(yīng)時(shí)間百分比和基準(zhǔn)響應(yīng)時(shí)間對(duì)配置成本的影響。實(shí)驗(yàn)結(jié)果表明,通過(guò)MPCA對(duì)云中心服務(wù)器數(shù)量和運(yùn)行速率進(jìn)行優(yōu)化,可以使配置成本隨著負(fù)載流量的增加而呈線性增長(zhǎng)。
[Abstract]:In order to ensure the percentage of response time (SLA) and minimize the cost of commercial cloud center resource allocation, a cloud center model based on queuing theory is proposed to analyze the cost of cloud center resource allocation from an economic point of view. The mathematical expression of cloud center response time percentage is derived. The minimum configuration cost algorithm (MPCA),) is presented to analyze the effects of load flow response time percentage and benchmark response time on configuration cost through a large number of experiments. The experimental results show that the configuration cost increases linearly with the increase of load flow by optimizing the number and running rate of cloud central servers by MPCA.
