Njengobuchule, ubuchwephesha be-Software Defined Networking (SDN) yinto ebaluleke gqitha ekuthobeleni phambili kwe-computing yefu. Ngaphezulu kweenyanga ezimbalwa zokugqibela, uphuhliso lwayo olukhulu luye lwaholela kwibheno ebalulekileyo ngokubhekiselele kumda womda. Enye into eninzi abaye bayayilibala malunga nelifu kukuba akuyiyo yedijithali ngokupheleleyo. Kwindawo enye okanye kwenye indawo ehlabathini, kufuneka kubekho idatha yedatha okanye iseva yomzimba esebenza njengengxangxube ye-computing yefu.
Kuthetha ukuthini oku kubathengisi bamafu?
Ukuze ugcine ijubane layo ngokukhula kwefu elimangalisayo, kufuneka bahlakulele inani elinyukayo lamaziko eenkcukacha, bawabeka emhlabeni jikelele ukunciphisa i-latency ukuya kumlinganiselo omkhulu kunabo bonke abathengi behlabathi. Abaninzi babo basebenzise isibonelelo sefu ukuze balawulwe kwezi zixhobo baze badibanise ndawonye.
Ngokuqhelekileyo, ibeka imfuno enyukayo kumanethiwekhi. Ngoko ke, ubugcisa be-intanethi bukho ngokukhawuleza buguqukela njengenye yeebhloko ezinkulu kwi-computing field. Umba wukuthi izixhobo zokusebenza ze-hardware azizange zivele ukuze zigcine ijubane kunye nefu nangona i-computing hardware inakho. Ngamazwi alula, akunakwenzeka ngokuthunyelwa lula okanye kungabonakali.
I-SDN Inyathelo
Imingeni phambi kwabaqhubi benethiwekhi kubanzi njengoko kulindeleke ukuba bavele ngezinga kunye neemfuno zabathengi. Imingeni ephambili kukuhlangabezana neemfuno ezikhulayo zokuhamba kwee-bandwidth kunye nokuthunyelwa ngokukhawuleza kweenkonzo ezintsha kubaxumi. Oku kuthetha ukuba abaqhubi benethiwekhi abayidingi nje inethiwekhi engabonakaliyo, kodwa nayo ibalulekileyo. Yilapho i-SDN ihamba khona.
Imfuno yeenethwekhi ezicwangcisiweyo, ezinokuthi zichazwe kwi-push push key emva kokusasazeka kwezixhobo zobuqu kunye nezinto zokusebenza zefu-ezimbini zeendlela ezinkulu ezihlangeneyo ziqhuba utshintsho oluyisiseko kubuhlobo phakathi kweqhinga lobugcisa kunye ne-IT. I-SDN inikeza ithuba lokukhawulezisa ukuhanjiswa kweenkcukacha kunye nokunciphisa iindleko.
Ngokwenene, i-SDN kukunxibelelwano oluqhelekileyo ukuba ilifu linikwe kwisiqulatho sesicatshulwa esiqhelekileyo. Iindlela ezisetyenziswayo, i-SDN elawulwayo, ihluke ngokupheleleyo kwi-hardware elawulayo-le pemethe epheleleyo ngokubanzi kunye nokugqibelela ukulungiswa kweekhompyutha kunye ne-hardware. Kwakhona kunika ngokuthe ngqo ukulungelelanisa kunye nezinga lokungahambikiyo olufunekayo ukwenzela ukuba ifu yekhompyutha iqhubekele phambili.
Ukongeza kwinqanaba lomda wendlela elungeleyo yokusebenza okungekho ukuyeka kunye nobuchwepheshe bokuzenzekelayo, i-SDN ibonisa esinye isinyathelo kwisiseko sezedijithali ngokupheleleyo kubathengisi kunye nabaxhasi. Ngokubhekiselele kwimisebenzi yomnatha, i-SDN ibonisa amaninzi afanelekileyo afana ne-computing efayili. Ukulungelelanisa ukuguquguquka kunye nobuchule buza kuvumela ukusebenzisa ngokufanelekileyo ukusetyenziswa kwezixhobo zonxibelelwano, ngelixa ukuhla kweendleko zokusebenza kungabangela ukwenziwa kwezinto ezintsha kunye nokulondolozwa okukhulu kwinxalenye yomthengi.
Cinga nayiphi na inkqubo - yonke ifana neyokusebenza njengemacandelo aloo nto - ifu ayikho kulo mgaqo.
Nangona kuyi nyaniso ukuba i-computing yefu enye yezona zixhobo ezinamandla kunako nayiphi na ishishini, ngelo xesha, ubunako bayo obupheleleyo abukwazi ukuzaliswa ukuba zilayishwe ngekhompyutha eziqhelekileyo zokunxibelelana. Yiyo kanye le nto i-SDN inokubambisana okubalulekileyo kunye nelifu.
Ngaphandle kwe-SDN, i-computing yefu nje ayikwazi ukuqhubeka nokuziphendukela kwayo, kunye nekhonkco phakathi kwe-computing yefu kunye ne-software ecacisiweyo yokunxibelelanisa inamandla kakhulu.
