Withthematurityofthenetworkresourceservicemarket,therearenowfourbasicwebsitesystemmethodsdeveloped:virtualhostingspace,virtualhosting(includingVPSAndcloudhosting),machinerentalandserverhosting.
ServerhostingmeansthatthecustomerownsaserverandplacesitinthecomputerroomoftheInternetdatacenterformaintenancebythecustomerhimself,orremotemaintenancebyothercontractors.

1.Whenacustomerchoosesaserver,thefirstconsiderationshouldbetohosttheapplicationservicesneeded,andthendeterminethehardwareandsoftwareconfigurationrequiredfortheservice
Previously,thecompanywaspreparingforhostingAtthetime,alwaysthinkaboutbuyingahigh-endserver,andthenwanttorenthowmuchbandwidthtohostyourownserver,insteadofchoosingaserverandIDCserviceproviderbasedonyouractualneeds,butthismethodwastesresourcesandincreasesTheuser’scapitalinvestment.
Whencompaniesbuildwebsitesordevelope-commerce,theydonotnecessarilyneedhigh-endorexpensiveservers,nordotheynecessarilyneedtorentalotofbandwidthfromIDC.Thecompanycandecidetobuyitsownserverbrandandconfigurationstandardsaccordingtoitsactualapplicationneeds.Ifyoudofreeemailservice,thenthestoragemustbelarger,andyoucanusemultipleharddrivesordiskarrays,orevennetworkstoragedevices.;Ifthereisadatabasequeryservice,thenthememorymustbelarger;ifthewebsitehasalargeamountofvisits,loadbalancingtechnologyisrequired;iftheamountofdataislarge,thenthedatabackupandaccidentdatarecoverytechnologymustbestrong.Generallyspeaking,whencompanieschooseservers,theymustchoosethebrandandserverconfigurationbasedontheirownapplicationneeds.Thereisnoneedtochoosethebestandmostexpensive.Itisthebestthatcanmeettheirownneeds.
2.Highconfigurationdoesnotmeanhighperformance.Stabilityandscalabilityarealsoveryimportant.
Thevariouscomponentsoftheserverareanorganicwhole,whichareconnectedandaffecteachother.Whenselectingaserver,thecompatibilityofeachpartmustbeconsidered,soastoachievethebestperformanceoftheconfiguration.Themostimportantindicatoroftheserverisstability,especiallytheserverrunninginIDC,itmustbe24×7×365workinghours,sothestabilityoftheserverisveryhigh,andtheymustbeabletoensuretheirstability,security,Worksnormally.Forthisreason,IDCsalsochooseIDCbusinessmanagementsystemswithsuperiorperformance,suchasforeignWHMCSordomesticIDCSystem.Operatorswithbetterservicesintheindustrycanprovidecustomerswith7*24freedayandnightundifferentiatedservicecommitments:

3.Thegeneral-purposeserverdevelopstothededicatedserver,theeaseofuseandspecializationareveryobvious
WiththedevelopmentoftheInternet,therequirementsofcustomersforserversareconstantlyimprovingandchanging.Therefore,general-purposeserverswillgraduallychangetoprofessionalservers.Takee-mailasanexample.Inthepast,e-mailservicesonlyneededtoinstallasetofe-mailsoftwareonanyservicetoprovidee-mailservices,regardlessofitsstability.,Regardlessofitsabilitytohandlemail,aslongasitcanbeused.Butthefactsarenotassimpleasimagined.Theemailserviceisdifferentfromthewebservice.Stabilityandserverresponsespeedareveryimportant.Therefore,adedicatedserverisrequiredtoprovideservices.Thefuturedevelopmenttrendofenterprisepostofficeserversshouldbeeaseofuseandspecialization.Theselectionandconfigurationoftheservershouldberelativelysimple,withouttoohightechnicalthreshold,andthedevelopmenttrendofspecializationwillbeveryobvious,whatkindofserviceWhatkindofcharacteristicswilltherebe,anddifferentcharacteristicsrequiredifferentproductstomeethisrequirements.
