I-Slurm SRE. Uvavanyo olupheleleyo kunye neengcali ezivela kwi-Booking.com kunye ne-Google.com

Iqela lethu liyayithanda imifuniselo. I-Slurm nganye ayilophindaphindo olumileyo lwezangaphambili, kodwa imbonakalo yamava kunye notshintsho ukusuka kokulungileyo ukuya kokungcono. Kodwa kunye I-Slurm SRE siye sagqiba ekubeni sisebenzise ifomathi entsha ngokupheleleyo - ukunika abathathi-nxaxheba iimeko ngokusondeleyo "ukulwa".

Ukuba sichaza ngokufutshane oko sikwenzileyo ebudeni besifundo esinzulu: “Siyakha, siyaphula, siyalungisa,
siyafunda." I-SRE ixabisa kancinane kwithiyori nje-ukwenza kuphela, izisombululo zokwenyani, iingxaki zokwenyani.

Abathathi-nxaxheba bahlulahlulwe ngamaqela ukuze umoya wokhuphiswano onamandla ungavumeli nabani na ukuba alale okanye aqalise "iiNyoni ezinomsindo" kwi-iPhone, ngokulandela umzekelo kaDmitry Anatolyevich.

Iingxaki, iingxaki, iimpazamo kunye nemisebenzi yanikwa abathathi-nxaxheba ngabacebisi abane. U-Ivan Kruglov, uMthuthukisi oyiNtloko kwi-Booking.com (eNetherlands). UBen Tyler, uMphuhlisi oyiNtloko kwi-Booking.com (USA). U-Eduard Medvedev, i-CTO kwi-Tungsten Labs (eJamani). U-Evgeniy Varavva, umphuhlisi jikelele kuGoogle (eSan Francisco).

Ngaphezu koko, abathathi-nxaxheba bahlulwe babe ngamaqela kwaye bakhuphisane omnye nomnye. Unomdla?

U-Ivan, u-Ben, u-Eduard no-Evgeniy bajonge abahluphekileyo be-Slurm abathathi-nxaxheba be-SRE abanobubele be-Leninist squints ngaphambi kokuqala kokhuphiswano.

Ngoko umsebenzi:

Singabethu, siya kwakha ihlabathi elitsha...

Kukho iwebhusayithi yokudibanisa amatikiti emuvi. Iziganeko ziyilwa ngabacebisi kwimeko esetyenziwe ngaphambili (nangona kungekho mntu ungabandakanyi ngokukodwa uphuculo oluntsonkothileyo noluchubekileyo), ukusebenza kwesiza kuchazwa ngeemetrics ezahlukeneyo. Iingxaki zinokwahluka kakhulu: amatikiti eMoulin Rouge theatre akalayishwanga kwisiseko sedatha; iipowusta zeefilimu kunye nemiboniso zilayishwa kwisiseko sedatha ngaphezu kwemizuzwana ye-10; inkcazo yefilim nganye iyaba ngumkhenkce; I-0,1% yee-odolo sele zigciniwe; Ngamaxesha ngamaxesha inkqubo yokuhlawula intlawulo iphazamiseka umzuzu okanye ezimbini. Kwaye ezininzi, zininzi, izinto ezininzi ezingathandekiyo ezinokuwela umthathi-nxaxheba weSlurm SRE emsebenzini wakhe wokwenyani.

Sikulungele ukuphatha nantoni na ... kwaye wonke umntu.

Iwebhusayithi yethu enomonde iqulathe ii-microservices ezininzi. Umsebenzi wayo kukudibanisa idatha kwimiboniso, amaxabiso kunye nezihlalo ezifumanekayo kuzo zonke iisinema; ibonisa izibhengezo zemuvi, ikuvumela ukuba ukhethe i-cinema, umboniso, iholo kunye nendawo, incwadi kwaye uhlawule amatikiti. Ngokubanzi, yonke into umbukeli anokuyiphupha kuphela. Kodwa umsebenzisi akade akrokre ukuba yintoni umzabalazo we-titanic wokuzinza kunye nokufikeleleka kwesiza ngaphakathi.

Kwindawo enzulu, senze i-SLO, i-SLI, izibonakaliso ze-SLA, i-architecture ephuhlisiwe kunye neziseko zophuhliso, sahambisa indawo, sibeka iliso kunye nokulumkisa. Kwaye siyahamba.

SLO, SLI, SLA

I-SLI - izikhombisi zenqanaba lenkonzo. Ii-SLO zinjongo zomgangatho wenkonzo. I-SLA - izivumelwano zomgangatho wenkonzo.

I-SLA yinkqubo ye-ITIL ye-methodology ebonisa isivumelwano esisemthethweni phakathi komthengi wenkonzo kunye nomthengisi wayo, equlethe inkcazo yenkonzo, amalungelo kunye nezibophelelo zamaqela kwaye, okona kubaluleke kakhulu, inqanaba elivunyelweneyo lomgangatho wokubonelela oku. inkonzo.

I-SLO yinjongo yenqanaba lenkonzo: ixabiso ekujoliswe kulo okanye uluhlu lwamaxabiso kumgangatho wenkonzo olinganiswa yi-SLI. Ixabiso eliqhelekileyo le-SLO lithi "SLI ≤ Ithagethi" okanye "Umda ophantsi ≤ SLI ≤ Upper Limit".

I-SLI yisalathisi somgangatho wenkonzo-umlinganiselo ochazwe ngokucokisekileyo wobungakanani benkalo enye yenqanaba lenkonzo enikezelweyo. Kwiinkonzo ezininzi, i-SLI engundoqo ithathwa njengesicelo sokulinda-ixesha elingakanani ukubuyisela impendulo kwisicelo. Ezinye ii-SLIs eziqhelekileyo ziquka izinga lemposiso, elidla ngokuchazwa njengeqhezu lazo zonke izicelo ezifunyenweyo, kunye nenkqubo yokuphuma kwenkqubo, edla ngokulinganiselwa kwizicelo ngesekhondi.

Okokuqala, siya kuqhekeza iindiza, kwaye emva koko amantombazana, kwaye ke amantombazana ...

Izinto zangaphakathi nangaphandle zaqala "ukonakalisa" i-SLO ukusuka kwimizuzu yokuqala. Yonke into yawela kwiintloko zabalawuli-iimpazamo zomphuhlisi, ukungaphumeleli kwezakhiwo, ukunyuka kweendwendwe, kunye nokuhlaselwa kweDDoS. Yonke into eyenza i-SLO ibe mandundu.

"- Abathathi-nxaxheba abathandekayo, ndikhawuleza ukukukholisa, into yokuqala osilela ngayo ... yonke into!"

Endleleni, izithethi zixubushe ukuzinza, uhlahlo lwabiwo-mali lwephutha, ukuvavanya ukuvavanya, ukulawula ukuphazamiseka kunye nomthwalo wokusebenza.

Asizizo iistokers, asingobachweli...

Emva koko abathathi-nxaxheba baqala ukulungisa izinto - into ephambili kukuqonda into yokubamba kuqala.

"- Nkosi, andizange ndiyibone iphuka ngolu hlobo, ngolu hlobo kwaye ikwimeko enjalo!"

Ngoko, kwenzeka ingozi. Inkonzo yokulungisa intlawulo iphantsi. Indlela yokwenza ukubuyisela ukusebenza ngexesha elifutshane kunokwenzeka?

Iingcali, zijonge ngothando kubathathi-nxaxheba, zilungiselela elinye iqhinga.

Iqela ngalinye liququzelela umsebenzi weqela ukuphelisa ingozi - ibandakanya oogxa, yazisa amaqela anomdla (abachaphazelekayo). Kwangaxeshanye, kumiselwa izinto eziza kuqala. Ngale ndlela, abathathi-nxaxheba baqeqeshelwa ukusebenza phantsi koxinzelelo phantsi kweemeko zexesha elincinci kakhulu.

"Luluphi uhlobo loloyiko oluphumileyo?!"

Exhale... kwaye ugqibezele umthambo

Kanye kunye nezithethi, emva kokuba ingxaki nganye isonjululwe kwaye isiza sazinziswa okwethutyana, iqela lafunda iziganeko ukusuka kwindawo yokujonga i-SRE. Sihlalutye iingxaki ngokweenkcukacha - izizathu zokwenzeka, inkqubela phambili yokuphelisa. Emva koko, zombini iqela-ngeqela kunye neqela, senze izigqibo malunga nendlela yokukhusela ngakumbi: indlela yokuphucula ukubeka iliso, indlela yokutshintsha ngobulumko i-architecture, indlela yokulungelelanisa indlela yophuhliso kunye nokusebenza, indlela yokulungisa imimiselo. Izithethi zibonise umkhwa wokwenza uhlolisiso lomzimba.

“Ngubani omnye ofuna intuthumbo! - Mna!"

Impumelelo yamaqela ishicilelwe ngokungqongqo nangokucacileyo kwibhodi yokukora yekhompyutha.

Kwiindawo zokuqala - ibhonasi evela kwabachaphazelekayo.
