Iyo epic nezve system administrator semhuka iri mungozi

Vatungamiriri vehurongwa kutenderera pasirese, makorokoto pazororo rako rehunyanzvi!

Isu hatina vatariri vehurongwa vakasara (zvakanaka, zvakada). Zvisinei, ngano pamusoro pavo ichiri itsva. Mukukudza kwezororo, takagadzirira iyi epic. Garai musununguke, vaverengi vanodiwa.

Pane imwe nguva nyika yeDodo IS yaibvira moto. Munguva iyoyo yerima, basa guru revatariri vedu vehurongwa raive rekurarama rimwe zuva uye kwete kuchema.

Kare kare, vagadziri vepurogiramu vakanyora kodhi zvishoma uye zvishoma nezvishoma, uye vakaitumira pane prod kamwe chete pasvondo. Saka matambudziko aimuka kamwe chete pamazuva manomwe oga oga. Asi vakabva vatanga kunyora kodhi yakawanda uye kuitumira kakawanda, matambudziko akatanga kuwedzera, dzimwe nguva zvinhu zvose zvakatanga kuparara, uye zvakatonyanya kuipa kudzoka shure. Masystem maneja akatambura, asi akashivirira iyi farce.

Vakagara kumba kwavo manheru vachinetsekana mumoyo. Uye nguva dzose zvakaitika "hazvina kumboitika, uye pano zvakare kutarisa kunotumira chiratidzo chekubatsira: Dude, nyika iri moto!". Ipapo vatariri vedu vehurongwa vakapfeka machira matsvuku emvura, zvikabudura pamusoro pema leggings, vakaita curl pahuma uye vakabhururuka kuti vaponese nyika yeDodo.

Attention, tsananguro shoma. Hakusati kwambove neClassic system administrator vanochengetedza Hardware muDodo IS. Takabva tangoenda paAzure clouds.

Chii chavakaita:

• kana chimwe chinhu chaputsika, vaigadzira kuti chigadzirwe;
• juggled servers pamwero wenyanzvi;
• vaive nebasa reiyo virtual network muAzure;
• vaiva nemhosva yezvinhu zvakaderera, semuenzaniso, kupindirana kwezvikamu (* kuzevezera * umo dzimwe nguva havana kutenderera);
• server inobatanidzazve;
• nemamwe akawanda emusango.

Hupenyu hwechikwata chemainjiniya ezvivakwa (sekudaidza kwatakaita masystem administrator) hwaive hwekudzima moto uye kugara uchipwanya mabhenji ebvunzo. Vakararama uye vakachema, uye vakabva vafunga kufunga: sei zvakashata, kana kuti zvichida tinogona kuita zviri nani? Semuenzaniso, isu hatizogovani vanhu kuva programmers uye system administrator?

dambudziko

Zvapiwa: kune sisitimu maneja ane maseva munzvimbo yake yebasa, network inomubatanidza kune mamwe maseva, zvivakwa-chikamu zvirongwa (webhu server inobata application, dhatabhesi manejimendi system, nezvimwewo). Uye kune programmer ane nzvimbo yebasa iri kushanda kodhi.

Uye pane zvinhu zviri pajunction. Basa raani iri?

Kazhinji, vatariri vedu vehurongwa nevagadziri vepurogiramu vakasangana pajunction iyi uye yakatanga:

"Varume, hapana chinoshanda, pamwe nekuda kwezvivakwa.
- Shamwari, kwete, iri mukodhi.

Rimwe zuva panguva ino, fenzi yakatanga kukura pakati pavo, iyo yavakakanda poop nemufaro. Basa racho, setsvina, rakakandwa kubva kune rumwe rutivi rwefenzi kuenda kune rumwe. Panguva imwe cheteyo, hapana akaswedera pedyo nekugadzirisa mamiriro acho ezvinhu. Sad smiley.

Kupenya kwezuva kwakabaya denga rakafukidzira apo makore mashoma apfuura paGoogle vakauya nepfungwa yekusachinjanisa mabasa, asi kuti vaite chinhu chakajairika.

Asi zvakadini kana tikatsanangura zvose sekodhi?

Muna 2016, Google yakabudisa bhuku rinonzi "Site Reliability Engineering" pamusoro pekushandurwa kwebasa remutungamiri wehurongwa: kubva kune tenzi wemashiripiti kuenda kune imwe nzira yeinjiniya yakagadziriswa mukushandiswa kwesoftware uye otomatiki. Ivo pachavo vakapfuura nemuminzwa yose nezvipingamupinyi, vakawana kurembera kwayo uye vakasarudza kuigovana nenyika. Bhuku racho riri muvanhu pano.

Bhuku racho rine chokwadi chiri nyore:

• kuita zvese sekodhi zvakanaka;
• shandisa nzira yeinjiniya - yakanaka;
• kuita kutarisa kwakanaka kwakanaka;
• kudzivirira sevhisi kuburitswa kana isina kutema matanda kwakajeka uye kutarisa kwakanaka zvakare.

Aya maitiro akaverengwa neGleb yedu (entropy), uye toenda. Implementing! Iye zvino tave muchikamu chekuchinja. Chikwata cheSRE chinoumbwa (kune nyanzvi nhanhatu dzakagadzirira, 6 dzimwe dziri paboarding) uye dzakagadzirira kushandura nyika, inosanganisira zvachose kodhi, kuti ive nani.

Isu tinogadzira zvivakwa zvedu nenzira yekugonesa vanogadzira kubata nharaunda yavo uye kubatana neSRE zvakasununguka.

Wang pane mhedziso

System administrator ibasa rakakodzera. Asi ruzivo rwechikamu chehurongwa hunodawo yakanakisa software engineering hunyanzvi.

Masisitimu ari kuita nyore uye nyore, uye ruzivo rwepamusoro-rwakasiyana-siyana rwekutungamirira maseva esimbi riri kuita shoma mukudiwa gore rega rega. Cloud matekinoroji ari kutsiva kudiwa kweruzivo urwu.

A good system administrator munguva pfupi iri kutevera anozofanirwa kuve neakanaka software engineering hunyanzvi. Kunyange zviri nani, anofanira kunge ane unyanzvi hwakanaka munharaunda iyi.

Hapana anoziva kufanotaura nezveramangwana risati raitika, asi isu tinotenda kuti nekufamba kwenguva kuchange kuine makambani mashoma uye mashoma anoda kuwedzera kune asingagumi bloated staff of system administrator. Kunyangwe, hongu, mafeni acharamba aripo. Vashoma nhasi vanokwira mabhiza, kunyanya vanoshandisa mota, kunyangwe paine vanoda ...

Happy sysadmin zuva munhu wese, kodhi kune wese!
