〔Abstract〕As a result of evolving of distributed processing,parallel processing and grid computing,cloud computing which is a new kind of commercial computation model has many advantages such as being safe and reliable,capable of mass data storage,as well as easy and convenient to use.The unique advantages of cloud computing has already caused the attention of various famous international companies and applied in various fields.Also it will greatly affect the development of libraries.Nowadays,libraries should contemplate how to adjust their services mode by using cloud computing,in order to effectively adapt themselves to the interactions between readers and libraries,and solve a series of problems in cloud computing such as data security,standard and intellectual property.
〔Key words〕cloud computing;distributed processing;parallel processing;grid computing;mass data storage
云計算(Cloud Computing),是一種基于互聯(lián)網(wǎng)的超級計算模式。狹義上講,它是分布式處理、并行處理和網(wǎng)格計算技術(shù)的綜合發(fā)展,是一種新型的計算模型,是一種新型的共享基礎(chǔ)架構(gòu)的方法。廣義上講,它是一種基于互聯(lián)網(wǎng)的計算方式,通過這種方式,共享的軟硬件資源和信息可以按需提供給計算機和其他設(shè)備對內(nèi)對外的服務(wù)。云計算的核心思想,是將大量用網(wǎng)絡(luò)連接的計算資源統(tǒng)一管理和調(diào)配,構(gòu)成一個計算資源池向用戶按需服務(wù)。提供資源的網(wǎng)絡(luò)被稱為“云”,“云”的出現(xiàn)簡化了IT架構(gòu)的實施,給人們提供了一種理想的方式,即IT應(yīng)用可以像水電煤氣等公共設(shè)施一樣,實時定制,隨時取用,按需付費。目前按照“云”的內(nèi)容,可以把云分為3種:提供資源的云,包括提供存儲、網(wǎng)絡(luò)、帶寬等,將“資源”網(wǎng)絡(luò)化、虛擬化,以服務(wù)的形式提供;……
