Ithimba lethu liyazithanda izivivinyo. I-Slurm ngayinye ayiyona impinda emile yangaphambilini, kodwa iwukubonisa ulwazi kanye noshintsho ukusuka kokuhle ukuya kokungcono. Kodwa nge sinqume ukusebenzisa ifomethi entsha ngokuphelele - ukunikeza abahlanganyeli izimo eziseduze kakhulu "zokulwa".
Uma sibeka kafushane lokho esakwenza phakathi nesifundo esijulile: “Siyakha, siyaphula, siyalungisa,
siyafunda." I-SRE ibaluleke kancane ngombono nje - ukuzilolonga kuphela, izixazululo zangempela, izinkinga zangempela.
Abahlanganyeli bahlukaniswa ngamaqembu ukuze umoya wokuncintisana onamandla ungavumeli noma ubani ukuba alale noma aqalise "Izinyoni Ezithukuthele" ku-iPhone, ngokulandela isibonelo sikaDmitry Anatolyevich.
Izinkinga, amaphutha, iziphazamisi kanye nemisebenzi inikezwe ababambiqhaza ngabeluleki abane. U-Ivan Kruglov, Unjiniyela Omkhulu kwa-Booking.com (Netherlands). U-Ben Tyler, Unjiniyela Omkhulu kwa-Booking.com (USA). Eduard Medvedev, CTO at Tungsten Labs (Germany). U-Evgeniy Varavva, unjiniyela jikelele e-Google (San Francisco).
Ngaphezu kwalokho, abahlanganyeli bahlukaniswe ngamaqembu futhi bancintisane. Kuyathakazelisa?
U-Ivan, u-Ben, u-Eduard no-Evgeniy babheka abahlanganyeli abampofu be-Slurm SRE abane-Leninist squints enomusa ngaphambi kokuqala komncintiswano.
Ngakho umsebenzi:
Singabethu, sizokwakha umhlaba omusha...
Kukhona iwebhusayithi yokuhlanganisa ithikithi le-movie. Izehlakalo ziqanjwe abeluleki esimeni esenziwe ngaphambilini (nakuba kungekho muntu obekela eceleni ukuthuthukiswa okuyinkimbinkimbi nokucashile), ukusebenza kwesayithi kuchazwa ngamamethrikhi ahlukahlukene. Izinkinga zingahluka kakhulu: amathikithi etiyetha ye-Moulin Rouge awalayishwa kusizindalwazi; amaphosta amafilimu nemidlalo alayishwa kusizindalwazi ngemizuzwana eyi-10; incazelo yefilimu ngayinye iba yiqhwa; 0,1% wama-oda asevele agodliwe; Ngezikhathi ezithile isistimu yokucubungula inkokhelo iphahlazeka umzuzu owodwa noma amabili. Futhi izinto eziningi, eziningi, eziningi ezingemnandi ezingahle zehlele umhlanganyeli we-Slurm SRE emsebenzini wakhe wangempela.
Sikulungele ukuphatha noma yini...kanye nawo wonke umuntu.
Isizindalwazi sethu esinesineke sinezinsiza ezincane ezimbalwa. Umsebenzi wayo ukuhlanganisa idatha yezinhlelo, izintengo nezihlalo ezitholakalayo kuwo wonke amasinema; ibonisa izimemezelo zamamuvi, ikuvumela ukuthi ukhethe indawo yesinema, umbukiso, ihholo nendawo, ubhukhe futhi ukhokhele amathikithi. Ngokuvamile, konke umbukeli angaphupha ngakho kuphela. Kodwa umsebenzisi akasoli ngisho nokuthi umzabalazo we-titanic wokuzinza nokufinyeleleka kwesayithi oqhubekayo ngaphakathi.
Esizeni esijulile, senze izinkomba ze-SLO, i-SLI, i-SLA, i-architecture ethuthukisiwe nengqalasizinda, satshala isayithi, samisa ukuqapha kanye nokuxwayisa. Futhi siyahamba.
I-SLO, i-SLI, i-SLA
I-SLI - izinkomba zezinga lesevisi. Ama-SLO ayimigomo yezinga lesevisi. I-SLA - izivumelwano zezinga lesevisi.
I-SLA yitemu le-ITIL lemethodology elisho isivumelwano esisemthethweni phakathi kwekhasimende lensizakalo nomphakeli walo, esiqukethe incazelo yesevisi, amalungelo nezibopho zezinhlangothi futhi, okubaluleke kakhulu, izinga lekhwalithi okuvunyelwene ngalo lokuhlinzekwa kwalokhu. isevisi.
I-SLO inhloso yeleveli yesevisi: inani eliqondiwe noma ububanzi bamanani weleveli yesevisi elinganiswa nge-SLI. Inani elivamile le-SLO lithi “SLI ≤ Target” noma “Umkhawulo Ophansi ≤ SLI ≤ Upper Limit”.
I-SLI iyinkomba yezinga lesevisi—isilinganiso sobuningi esichazwe ngokucophelela sesici esisodwa sezinga lesevisi enikeziwe. Kumasevisi amaningi, ukhiye we-SLI uthathwa njengokubambezeleka kwesicelo - kuthatha isikhathi esingakanani ukubuyisela impendulo esicelweni. Amanye ama-SLI avamile ahlanganisa isilinganiso samaphutha, ngokuvamile esivezwa njengengxenye yazo zonke izicelo ezitholiwe, kanye nokuphuma kwesistimu, ngokuvamile kulinganiswa ngezicelo ngomzuzwana.
Okokuqala sizophula izindiza, bese kuba amantombazane, bese kuba amantombazane...
Izici zangaphakathi nezangaphandle zaqala "ukonakalisa" i-SLO kusukela emaminithini okuqala. Konke kwawela emakhanda abalawuli—amaphutha kanjiniyela, ukwehluleka kwengqalasizinda, ukutheleka kwezivakashi, nokuhlaselwa kwe-DDoS. Konke okulimaza i-SLO.
"- Bahlanganyeli abathandekayo, ngiphuthuma ukunijabulisa, into yokuqala enihlulekayo ... konke!"
Endleleni, izikhulumi zidingide ukuzinza, isabelomali samaphutha, umkhuba wokuhlola, ukuphathwa kokuphazamiseka kanye nomthwalo wokusebenza.
Asiwona ama-stokers, akubona ababazi...
Khona-ke abahlanganyeli baqala ukulungisa izinto - into esemqoka ukuqonda ukuthi yini okufanele uyibambe kuqala.
"- Nkosi, angikaze ngiyibone iphuka kanje, ikulesi simo futhi ikusimo esinje!"
Ngakho, kwenzeka ingozi. Isevisi yokucubungula inkokhelo iphansi. Indlela yokwenza ukubuyisela ukusebenza ngesikhathi esifushane kakhulu?
Ochwepheshe, bebheka ngothando ababambiqhaza, balungiselela elinye iqhinga.
Ithimba ngalinye lihlela umsebenzi weqembu ukuze kuqedwe ingozi - libandakanya ozakwabo, lazisa abathintekayo (ababambe iqhaza). Ngesikhathi esifanayo, izinto eziza kuqala ziyabekwa. Ngale ndlela, ababambiqhaza baqeqeshelwa ukusebenza ngaphansi kwengcindezi ngaphansi kwezimo zesikhathi esilinganiselwe kakhulu.
"Luhlobo luni lokwethuka oluphumile?!"
Exhale... bese uqedela umsebenzi
Kanye nezikhulumi, ngemva kokuba inkinga ngayinye isixazululiwe futhi isayithi lizinzile okwesikhashana, ithimba lafunda izigameko ngokubuka kwe-SRE. Sihlaziye izinkinga ngokuningiliziwe - izimbangela zokuvela, ukuqhubeka kokuqedwa. Ngemva kwalokho, kokubili ithimba neqembu futhi ngokuhlanganyela, senze izinqumo zokuthi singaqhubeka kanjani sibavimbele: indlela yokuthuthukisa ukuqapha, indlela yokuguqula ngokuhlakanipha isakhiwo, ukulungisa indlela yokuthuthukiswa nokusebenza, indlela yokulungisa imithetho. Izikhulumi zikhombise umkhuba wokwenza ukuhlolwa kwesidumbu.
“Ubani omunye ofuna ukuhlushwa! - Mina!"
Impumelelo yamaqembu iqoshwe ngokuqinile nangokucacile ebhodini lokushaya le-elekthronikhi.
Ezindaweni zokuqala - ibhonasi evela kubabambiqhaza.
