Izinto Kwezomnotho Wekhasi

Igama elithi "wekhasi" esanda zithandwa kakhulu. izixazululo Virtual ngezindlela ezingafani, asetshenziswa iningi e-formational izinhlelo. Ochwepheshe ukuzisebenzisa ukuhlola zinjongo, imisebenzi eyengeziwe ngezinto zokusebenza ezikhona, ukuqeqeshwa, kanye nokunye. N. Virtualizes amaseva, workstations, isitoreji izinhlelo, ingqalasizinda.

izici Kwezomnotho wekhasi

Ngaphambi kokuba bathathe ukuqaliswa izinhlelo virtual, kufanele ucabangisise ufuna ukuthola yi futhi kungakanani lubekelwe lokho thina. Naphezu kweqiniso lokuthi cishe zonke isethulo, sizozwa mayelana nezindleko-ukusebenza kwe- ubuchwepheshe, ngokomthetho ukuqaliswa wekhasi ephelezelwa izindleko futhi ngempela umxhwele.

Okokuqala, wekhasi kudinga ingqalasizinda IT, ezifana uhlelo isitoreji exhunywe kwi amaseva amaningi.

Okwesibili, i-software evumela ukuthi wena ukusizakala ezindaweni virtual: uthuthe imishini virtual .. Kusuka iseva ngokomzimba eyodwa kuya kwenye esikhathini sangempela, ukulinganisela phakathi kwemithwalo yakho umthwalo kumaseva ngokomzimba, kokuvala imishini ubuningi, njll - kuyinto ngenhloso yokuthengisa nokwenze kwaba elithe umkhiqizo ezibizayo. Ngenxa yalokho, umphumela kwezomnotho ka kwathatha indawo ebonakalayo kufinyelelwa, kusukela inombolo ethile amaseva. Uma akudingeki ngokushesha ukufaka amaseva entsha 10, uzoba ukuthenga imishini emisha ngesikhathi esisodwa futhi, okusekelwe nokubekwa zonke izinhlelo esizayo.

Ukuphumelela ukuphathwa isengezo wemishini eyinkimbinkimbi ezimweni zethu kuyaqabukela kungenzeka ukulinganisa e izibalo, ngoba abasebenzi kushintsha phakathi ochwepheshe IT ibhizinisi (isibonelo, wanciphisa inani uhlelo abaqondisi noma edonsa Outsourcing IT) Ukulandela ukwethulwa wekhasi izixazululo ingekho, futhi iseva ugesi izindleko zebhizinisi akuzona ngokuvamile abalwa wodwa eceleni.

Ngenxa yalokho, ukwethulwa wekhasi ngokuvamile kuphela kuholela izindleko ezengeziwe mayelana nokugcinwa ingqalasizinda IT kanye iseva abaphathi

I Onjiniyela izisombululo virtual

Kukhona wekhasi ubuchwepheshe eziningana akhiwa nabathengisi ezahlukene. Nansi nje uhlu emfushane kunazo kakhulu esetshenziswa umkhuba wekhasi izixazululo. umholi emakethe Wekhasi namuhla imikhiqizo at VMware. Solutions kusukela VMware inikeza wekhasi cishe lonke uhla wokusebenza (lwe-Windows, i-Linux, i-Apple-Macintosh, nokunye. D.), Ngokusho inkampani uvalwe afundziswe ngekuhlanganiswa amakhono hardware zamapulatifomu abaningi, ukusebenza ubuchwepheshe izixazululo iphutha-ukubekezela, nokunye. N. Ububanzi software bethula basakaza njengoba ngokukhululekile ( hypervisor ESXi), kanye nemikhiqizo bezentengiselwano.

hypervisor XEN kusekelwe yomthombo ovulekile, elaba kwandulela eziningi yomthombo ovulekile izixazululo.

Ngesisekelo le nkampani Citrix hypervisor ukwakha iseva XenServer, okuyilona elisebenzayo futhi izixazululo khulula. Nokho, ngokuvumelana eyodwa ukuphathwa XenServer iseva iwumkhiqizo kwezohwebo.

Sun (manje Oracle) kukhishwa VM VirtualBox. Le isixazululo imahhala futhi ingalandwa kusukela website Oracle. Inkampani Oracle onekhambi ngokuba VDI - Oracle Virtual Desktop Ingqalasizinda (i-VDI) , futhi inguqulo abafika kwabangu-10 amadeskithophu virtual ke angahlolwa mahhala isikhathi esinganqunyelwe.

Njengengxenye izinhlelo iseva yokusebenza Windows 2008, kukhona hypervisor - HyperV, okuyinto ingalandwa kusukela website Microsoft futhi umkhiqizo ehlukile futhi ingasetshenziswa ngokuphelele mahhala. imikhiqizo yomthombo ovulekile ubelokhu uqale ukusebenzisa isixazululo wekhasi igama KVM (isibonelo, hypervisor kufakwe Ubuntu, RedHat, nokunye. d.). I hypervisor KVM nokobana wekhasi ku-Linux-izinhlelo futhi itholakala njengengxenye ukusatshalaliswa efanele, kanye ngokusebenzisa ukufakwa amaphakheji.
