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:
