1.1BackgroundInformation

Withtherapiddevelopmentofeconomyandsociety,scienceandtechnologyhavebeenimprovedcontinuously.Decadesaftercomputersshowedup,moreandmorepeoplehaveonecomputerorseveralcomputersandtheytakethecomputerasaveryimportantelectricequipment,nomatterinworking,studyingorentertaining.Yearafteryear,peoplearenotanylongersatisfiedwiththebasicfunctions,butstarttoexploremoreintermsofthefunctions,suchastherelevanceofthequalityofperformance,alongwiththebreakthroughofvisualeffectsetc.（Derrick,2013）.

Becauseofthat,theideaofcloudtechnologycameup.Theideaofcloudtechnologyisthatthiskindoftechnologylinksresourcesinthefilesofcomputer,resourecsinthestoragespace,togetherwithresourcesinthesoftwarstovirtuallyestablishahugesharedITresourcespool.CloudtechnologyprovidesunlimitedITserviceswiththeideaofCalledforthem,marchingorderstogo,whichmeansonepersondoesnotneedhishardwarestorageequipmentanymore,justloginhisaccountonthecloud,andhecouldgetallhisbackupfile.That'
