Background

TheInternetbegantorisein1960,mainlyusedfortext-onlye-mailsornewsclusterservicesbetweenthemilitaryandlargeenterprises.Itwasn'tuntil1990thatpeoplebegantoenterordinaryfamilies.Withthedevelopmentofwebsitesande-commerce,theInternethasbecomeoneofthenecessitiesoflifethatpeoplecannotlivewithout.TheconceptofcloudcomputingwasfirstproposedatthesearchengineconferenceinAugust2006andbecamethethirdrevolutionoftheInternet.

Inrecentyears,cloudcomputinghasalsobecomeastrategicfocusofthedevelopmentoftheinformationtechnologyindustry,andglobalinformationtechnologycompaniesaretransformingtocloudcomputingoneafteranother.Forexample,everycompanyneedstododatainformationization,storerelatedoperationaldata,performproductmanagement,personnelmanagement,financialmanagement,etc.,andthebasicequipmentforthesedatamanagementisacomputer.

Foracompany,thecomputingpowerofacomputerisfarfrommeetingitsdatacomputingneeds,sothecompanymustpurchaseacomputerwithstrongercomputingpower,thatis,aserver.Forarelativelylarge-scaleenterprise,thecomputingpowerofoneserverisobviouslynotenough,sotheenterpriseneedstopurchasemultipleservers,orevenevolveintoadatacenterwithmultipleservers,andthenumberofserverswilldirectlyaffectthisThebusinessprocessingcapabilitiesofthedatacenter.Inadditiontothehighinitialconstructioncosts,themoneyspentonelectricitybillsincomputeroperatingexpendituresismuchhigherthantheinvestmentcosts.Coupledwithcomputerandnetworkmaintenanceexpenses,thesetotalcostsaredifficultforsmallandmedium-sizedenterprisestobear.,Sotheconceptofcloudcomputingcameintobeing.

DevelopmentHistory

Ithasbeenalmost10yearssincetheconceptofcloudcomputingwasproposed.Duringthese10years,cloudcomputinghasachievedrapiddevelopmentandearth-shakingchanges.Nowadays,cloudcomputingisregardedasarevolutioninthefieldofcomputernetworks,becauseofitsemergence,socialworkingmethodsandbusinessmodelsarealsoundergoingtremendouschanges.

Tracingbacktotherootofcloudcomputing,itsemergenceanddevelopmentarecloselyrelatedtotheaforementionedparallelcomputing,distributedcomputingandothercomputertechnologies,whichpromotethegrowthofcloudcomputing.Butthehistoryofcloudcomputingcanbetracedbackto1956,whenChristopherStracheypublishedapaperonvirtualizationandformallyputforwardtheconceptofvirtualization.Virtualizationisthecoreoftoday'scloudcomputinginfrastructureandthefoundationforthedevelopmentofcloudcomputing.Then,withthedevelopmentofnetworktechnology,thegerminationofcloudcomputingwasgraduallybred.

Inthe1990s,therewasabigexplosionincomputernetworks,andaseriesofcompanies,representedbyCisco,appeared,andthenthebubbleeraappearedintheInternet.

In2004,theWeb2.0conferencewasheld,andWeb2.0becameahotspotatthattime.ThisalsomarkedtheburstingoftheInternetbubbleandthedevelopmentofcomputernetworkshasenteredanewstage.Atthisstage,allowingmoreuserstousenetworkservicesconvenientlyandquicklyhasbecomeanurgentproblemtobesolvedinthedevelopmentofnetworking.Atthesametime,somelargecompanieshavealsobeguntodevotethemselvestothedevelopmentoflarge-scalecomputingtechnology,providinguserswithmorepowerfulComputingprocessingservices.

OnAugust9,2006,GoogleCEOEricSchmidtfirstproposedtheconceptof"CloudComputing"attheSearchEngineConference(SESSanJose2006).Thisisthefirsttimeinthehistoryofcloudcomputingthatthisconcepthasbeenformallyproposed,andithasgreathistoricalsignificance.

Since2007,"cloudcomputing"hasbecomeoneofthemostinterestingtopicsinthecomputerfield,anditisalsoanimportantresearchdirectionforlargeenterprisesandInternetconstruction.Becauseoftheproposalofcloudcomputing,newmodelsofInternettechnologyandITserviceshaveemerged,triggeringarevolution.

In2008,Microsoftreleaseditspubliccloudcomputingplatform(WindowsAzurePlatform),whichopenedthecurtainofMicrosoft'scloudcomputing.Similarly,cloudcomputinghasalsocausedastorminChina,andmanylargenetworkcompanieshavejoinedthecloudcomputingarrayoneafteranother.

InJanuary2009,AlibabaSoftwareestablishedthefirst"E-commerceCloudComputingCenter"inNanjing,Jiangsu.InNovemberofthesameyear,ChinaMobile'scloudcomputingplatform"Dayun"planwaslaunched.Atthisstage,cloudcomputinghasdevelopedtoamorematurestage.

OnAugust17,2019,theBeijingInternetCourtissuedthe"WhitePaperontheJudicialApplicationofInternetTechnology".Atthepressconference,theBeijingInternetCourtInternetTechnologyJudicialApplicationCenterwasinauguratedandestablished.
