I-DevOps vs SRE
Isingeniso:
I-DevOps ne-SRE amagama amabili avame ukusetshenziswa ngokushintshana, kodwa empeleni anezinjongo ezihluke kakhulu. I-DevOps isho isethi yezinqubo nezimiso ezigxile ekwenzeni izinqubo ngokuzenzakalela phakathi kwazo isofthiwe ukuthuthukiswa kanye namaqembu e-IT ukuze kuthuthukiswe ukusebenzisana, ukusheshisa imijikelezo yokuthuthukiswa, nokunciphisa isikhathi sokuya emakethe ngezici ezintsha. Ngakolunye uhlangothi, i-Site Reliability Engineering (SRE) isiyalo sobunjiniyela esigxile ekuqinisekiseni ukwethembeka kwezinhlelo ngokusebenzisa i-automation, ukuqapha, kanye nezinqubo zokuphatha izigameko ukuze kugcinwe impilo nokutholakala kohlelo.
Iyini i-DevOps?
I-DevOps iyindlela yokuphatha ukuthuthukiswa kwesofthiwe namathimba okusebenza akhuthaza ukubambisana phakathi konjiniyela, abasebenzi bokusebenza, nabanye ababambiqhaza. Ifuna ukunciphisa isikhathi esidingekayo sokukhishwa kwezici ezintsha ngokwandisa okuzenzakalelayo nokunciphisa izinqubo ezenziwa ngesandla. I-DevOps isebenzisa okuhlukahlukene Amathuluzi, njenge ukuhlanganiswa okuqhubekayo (CI) kanye nokulethwa (CD), izinhlaka zokuhlola, namathuluzi okuphatha ukucushwa (CM) ukuze kube lula ukusebenzisana nokuzenzakalela.
Iyini i-SRE?
Ngokuphambene, iSite Reliability Engineering (SRE) isiyalo sobunjiniyela esigxile ekuqinisekiseni ukwethembeka kwezinhlelo ngokusebenzisa izinqubo ezizenzakalelayo, ukuqapha, kanye nezinqubo zokuphatha izigameko ukuze kugcinwe impilo nokutholakala kwesistimu. Lokhu kufaka phakathi imisebenzi efana nokuhlola ukusebenza, ukuhlela amandla, nokulawula ukuphela. I-SRE isebenzisa okuzenzakalelayo ukuze yehlise umsebenzi owenziwa mathupha odingekayo emisebenzini yokusebenza, ukuze amaqembu akwazi ukugxila ekulungiseni okusebenzayo esikhundleni sokucisha umlilo.
Ukufana:
Nakuba le miqondo yomibili ihluka enjongweni yayo kanye nobubanzi bemisebenzi, kukhona ukufana okuthile phakathi kwayo. Kokubili i-DevOps ne-SRE zithembele kakhulu ku-automation ukuze kuqinisekiswe izinqubo ezisebenza kahle, ezithembekile neziphindaphindekayo; zombili zigcizelela ukubaluleka kwezinhlelo zokuqapha ukuze kutholakale izinkinga ezingase zibe izinkinga ngaphambi kokuba zibe izinkinga; futhi bobabili basebenzisa amasu okulawula izigameko ukuze baxazulule ngokushesha noma yiziphi izinkinga eziphakamayo.
Umehluko:
Umehluko oyinhloko phakathi kwe-DevOps ne-SRE ukugcizelelwa okubekwe ezicini ezihlukene zokuthembeka kwesistimu. I-DevOps igxile kakhulu ekuzenzekeleni nasekusebenzeni kahle kwenqubo ukuze kusheshiswe imijikelezo yentuthuko, kuyilapho i-SRE igcizelela ukuqapha okusebenzayo nokuphathwa kwezigameko ukuze kugcinwe impilo yesistimu nokutholakala. Ngaphezu kwalokho, i-SRE ngokuvamile ihilela ububanzi obubanzi bemisebenzi kune-DevOps, okuhlanganisa izindawo ezifana nokubuyekezwa kwedizayini yobunjiniyela, ukuhlelwa kwamandla, ukuthuthukiswa kokusebenza, izinguquko zesakhiwo sesistimu, njll., ezingahlotshaniswa ngokwesiko ne-DevOps.
Isiphetho:
Sengiphetha, i-DevOps ne-SRE yizindlela ezimbili ezihlukene ezinezinhloso ezahlukene. Nakuba kunokufana okuthile phakathi kwale mikhakha emibili, ukugxila kwayo okuyinhloko kusezicini ezihlukene zokwethembeka kwesistimu. Ngakho-ke, kubalulekile ukuthi izinhlangano ziqonde ukuthi indlela ngayinye ingabazuzisa kanjani ukuze zisebenzise kahle izinsiza ezitholakalayo nobuchwepheshe. Ngokuqonda umehluko nokufana phakathi kwe-DevOps ne-SRE, izinhlangano zingaqinisekisa ukuthi zisebenzisa kakhulu izinqubo zazo zokwethembeka kwesistimu.
