Internet vs Cloud Computing
Internet yog lub network thoob ntiaj teb ntawm ntau txhiab lab lub khoos phis tawj sib txuas thoob ntiaj teb. Nws muaj ntau yam kev pabcuam thiab kev pabcuam xws li World Wide Web thiab email. Piv txwv li, World Wide Web muab cov neeg siv nkag mus rau trillions ntawm hyperlinked cov ntaub ntawv. Tsis ntev los no, kev tsom mus rau kev muab tag nrho cov peev txheej (uas yog ib txwm muaj nyob hauv zos) hauv Is Taws Nem. Cloud Computing yog qhov tshwm sim ncaj qha ntawm qhov kev pib no, uas muaj ntau yam kev pabcuam xws li software, platforms thiab infrastructure ua cov kev pabcuam.
Cloud Computing yog dab tsi?
Huab suav yog cov thev naus laus zis tshiab ntawm kev xa ntau yam kev pabcuam raws li kev pabcuam, feem ntau hauv Is Taws Nem. Kev xa khoom yog hu ua cov chaw muab kev pabcuam, thaum cov neeg siv hu ua cov neeg siv khoom. Cov neeg siv khoom them tus nqi sau npe feem ntau ntawm ib qho kev siv. Kev suav huab tau muab faib ua ob peb pawg sib txawv raws li hom kev pabcuam. SaaS (Software as a Service) yog qeb ntawm huab xam uas cov peev txheej tseem ceeb muaj raws li qhov kev pabcuam yog cov ntawv thov software. PaaS (Platform as a Service) yog qeb / daim ntawv thov huab cua uas cov chaw muab kev pabcuam xa cov khoos phis tawj lossis kev daws teeb meem rau lawv cov neeg siv khoom hauv Is Taws Nem. IaaS (Infrastructure as a Service) yog qeb ntawm huab xam uas cov peev txheej tseem ceeb muaj raws li kev pabcuam yog cov khoom siv kho vajtse. DaaS (Desktop as a Service), uas yog qhov kev pabcuam tshiab -aaS cuam tshuam nrog kev muab tag nrho desktop kev paub dhau los hauv Is Taws Nem. Qhov no qee zaum hu ua desktop virtualization / virtual desktop lossis hosted desktop.
Internet yog dab tsi?
Internet (daim ntawv luv rau kev ua haujlwm hauv internet) yog lub network thoob ntiaj teb ntawm kev sib txuas hauv computer. Nws yog ib qho kev sib txuas ntawm cov tes hauj lwm, uas txuas ntau lab lub khoos phis tawj uas koom nrog ntau lab tus pej xeem, ntiag tug, tsoomfwv thiab kev kawm network. Internet siv TCP/IP (Transfer Control Protocol/Internet Protocol) rau kev sib txuas lus ntawm cov khoos phis tawj sib txuas. Cov txheej txheem tseem ceeb hauv Is Taws Nem (IPv4 thiab IPv6) tau tsim los ntawm IETF (Internet Engineering Task Force). Cov khoos phis tawj txuas nrog lub cev los ntawm kev siv tshuab hluav taws xob, kho qhov muag thiab wireless. Hypertext cov ntaub ntawv uas tsim lub Ntiaj Teb Wide Web thiab cov txheej txheem tsim nyog rau email yog ob qho ntawm cov khoom siv dav dav / kev pabcuam uas nqa los ntawm Is Taws Nem. Nrog kev qhia txog cov kev pabcuam xws li VoIP (Voice over Internet Protocol) thiab IPTV, ntau yam kev sib txuas lus ib txwm siv (xws li xov tooj, ntawv xov xwm thiab TV) tau hloov kho. Cov ntawv luam tawm ib txwm muaj xws li cov ntawv xov xwm thiab cov phau ntawv tam sim no muaj nyob rau hauv lub vev xaib, blogs lossis pub. Internet tau ua rau lub ntiaj teb no qhov chaw me me los ntawm nws cov txheej txheem ntau yam rau kev sib tham (xws li Instant Messaging, forums, chat room and Social Networking). Tsis tas li ntawd, E-kev lag luam tau dhau los ua lag luam ib txwm muaj.
Qhov txawv ntawm Internet thiab Cloud Computing yog dab tsi?
Internet yog lub network ntawm tes hauj lwm, uas muab software / hardware infrastructure los tsim thiab tswj kev sib txuas ntawm cov khoos phis tawj nyob ib puag ncig lo lus, thaum huab xam yog cov thev naus laus zis tshiab uas muab ntau hom kev pab hauv Is Taws Nem. Yog li Cloud laij lej tuaj yeem raug txheeb xyuas tias yog ib qho kev siv thev naus laus zis uas siv Internet ua qhov nruab nrab kev sib txuas lus los xa nws cov kev pabcuam. Cov kev pabcuam huab tuaj yeem muab rau hauv kev lag luam los ntawm LANs tab sis qhov tseeb, Huab suav tsis tuaj yeem ua haujlwm thoob ntiaj teb yam tsis muaj Is Taws Nem.
