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.
