Iyini Inhloso Yezinga Lesevisi?
Isingeniso:
I-Service Level Objective (SLO) yisivumelwano phakathi komhlinzeki wesevisi kanye nekhasimende ezingeni lesevisi okufanele lihlinzekwe. Isebenza njengesilinganiso sokuqinisekisa ukuthi ikhwalithi yesevisi okuvunyelwene ngayo iyagcinwa ngokuhamba kwesikhathi. Ama-SLO angasetshenziswa ezimbonini eziningi ezahlukene, njenge-cloud computing, isofthiwe ubunjiniyela, izinsiza ze-IT, kanye nezokuxhumana.
Izinhlobo zama-SLO:
Ama-SLO angahluka kuye ngemboni, kanye nemiphumela efiselekayo yomhlinzeki wesevisi. Ngokuvamile kunezinhlobo ezintathu zama-SLO: ukutholakala (isikhathi esengeziwe), amamethrikhi okusebenza, nokwaneliseka kwekhasimende.
Ukutholakala:
Uhlobo oluvame kakhulu lwe-SLO ukutholakala kwe-SLO. Lokhu kulinganisa ukuthi isevisi noma isistimu itholakala kaningi kangakanani futhi isebenza ngendlela efanele esikhathini esithile. Ukutholakala kufanele kuvezwe ngemibandela efana nokuthi “isevisi izotholakala u-99.9% wesikhathi” noma “isikhathi sokuphumula esiphezulu akumele sidlule iminithi elingu-1 ngosuku.”
Amametwork Performance:
Amamethrikhi okusebenza akala isivinini lapho imisebenzi iqedwa khona isistimu noma isevisi. Lolu hlobo lwe-SLO lungachazwa ngokuthi “isistimu kufanele iqedele imisebenzi phakathi kwamasekhondi angu-5” noma “isikhathi sokuphendula akumele sidlule imizuzwana engu-0.1 kunoma yisiphi isicelo.”
Ukwaneliseka Kwekhasimende:
Okokugcina, ama-SLO okwanelisa amakhasimende akala ukuthi amakhasimende aneliseke kangakanani ngesevisi ayitholayo. Lokhu kungafaka amamethrikhi afana nempendulo yekhasimende, izilinganiso, nezikhathi zokulungiswa kwamathikithi okusekela. Umgomo uwukuqinisekisa ukuthi isevisi ihlangabezana noma idlula lokho okulindelwe ngamakhasimende ngokunikeza izimpendulo zekhwalithi ephezulu ngokushesha nangempumelelo.
Izinzuzo:
I-SLO ivumela amakhasimende ukuthi azi ukuthi atholani kumhlinzeki wabo wesevisi futhi ihlinzeka izinhlangano ngendlela yokulinganisa ukusebenza ngokuhamba kwesikhathi. Lokhu kubasiza ukuthi baqonde kangcono ukuthi izinqubo ezithile noma amasevisi asebenza kahle kangakanani futhi kubavumela ukuthi benze izinguquko lapho kudingeka khona. Ukwengeza, ukuba nama-SLO acacile akhona kuqinisekisa ukuthi zombili izinhlangothi zinokulindela okuqondwa ngokucacile.
Ama-SLO futhi avumela izinkampani ukuthi zithuthukise ukwaneliseka kwamakhasimende ngokunikeza izinsizakalo ezihlangabezana nezidingo zamakhasimende kanye nokulindelwe. Lokhu kusiza izinhlangano ukuthi zenze ulwazi olunzulu ngomsebenzisi olungcono, kanye nokuhlinzeka ngokuthula kwengqondo kumakhasimende angathemba abahlinzeki bawo besevisi ukuthi balethe izinga lesevisi abalilindele.
Yiziphi Izingozi Zokungasebenzisi I-SLO?
Ukungabi ne-SLO endaweni kungase kube yingozi empumelelweni yenhlangano, njengoba kuyishiya ingenayo indlela yokubamba abahlinzeki bayo besevisi baphendule ngokusebenza kabi noma izinsizakalo ezinganele. Ngaphandle kwe-SLO, amakhasimende angase angalitholi izinga lesevisi ayilindele futhi angabhekana nemiphumela efana nesikhathi sokuphumula esingalindelekile noma izikhathi zokuphendula ezihamba kancane. Ukwengeza, uma inkampani ingenakho okulindelwe okucacile kumhlinzeki wayo wesevisi, kungaholela ekungaqondini okungase kubangele ezinye izinkinga phansi komugqa.
Isiphetho:
Sekukonke, Izinjongo Zezinga Lesevisi ziyingxenye ebalulekile yanoma ibuphi ubuhlobo bebhizinisi nekhasimende. Ngokuqinisekisa ukuthi zombili izinhlangothi ziqonda ngokucacile isevisi efiselekayo namazinga ekhwalithi, ama-SLO asiza ukuqinisekisa ukuthi amakhasimende athola inani elingcono kakhulu lemali yawo mayelana nokulethwa kwezinsizakalo. Ukwengeza, ukuba ne-SLO emisiwe endaweni kuvumela izinhlangano ukuthi zilinganise kalula ukusebenza ngokuhamba kwesikhathi futhi zenze izinguquko uma kudingeka. Ngakho-ke, kubalulekile ukuthi amabhizinisi abe ne-SLO ukuze aqinisekise impumelelo nokwaneliseka kwamakhasimende.
