Ahoj, Habr! Predstavujem v\u00e1m preklad \u010dl\u00e1nku \u201eP\u00f4vod DevOps: \u010co znamen\u00e1 n\u00e1zov?\u201c<\/a><\/noindex> autor Steve Mezak.<\/p>\n

Z h\u013eadiska va\u0161ej perspekt\u00edvy, DevOps bude tento rok oslavova\u0165 svoje deviate alebo desiate v\u00fdro\u010die. V roku 2016 sa vo spr\u00e1ve spolo\u010dnosti RightScale o stave cloudov uv\u00e1dzalo, \u017ee 70 percent mal\u00fdch a stredn\u00fdch podnikov prijalo met\u00f3dy DevOps. Ka\u017ed\u00fd indik\u00e1tor, ktor\u00fd tvori t\u00fato \u0161tatistiku, odvtedy vzr\u00e1stol. K\u00fdm sa DevOps chyst\u00e1 vst\u00fapi\u0165 do svojej druhej dek\u00e1dy, bolo by skvel\u00e9 prejs\u0165 sa po z\u00e1kutiach minulosti a vr\u00e1ti\u0165 sa k jeho kore\u0148om \u2013 a dokonca aj k p\u00f4vodu samotn\u00e9ho tohto n\u00e1zvu.

Do roku 2007: Ide\u00e1lny sled udalost\u00ed<\/h1>\n

\nDo roku 2007 s\u00e9ria okolnost\u00ed nakoniec dala \u017eivot tomu, \u010do dnes pozn\u00e1me ako DevOps.<\/p>\n

\u0160t\u00edhla v\u00fdroba<\/b> sa u\u017e osved\u010dila ako najlep\u0161ia prax. Tie\u017e zn\u00e1ma ako v\u00fdrobn\u00e9 syst\u00e9my Toyota<\/b>, \u0161t\u00edhla v\u00fdroba sa sna\u017e\u00ed o optimaliz\u00e1ciu procesov vo v\u00fdrobnom z\u00e1vode. (Mimochodom, vedenie Toyoty bolo p\u00f4vodne in\u0161pirovan\u00e9 origin\u00e1lnymi met\u00f3dami mont\u00e1\u017enej linky, ktor\u00e9 predstavila spolo\u010dnos\u0165 Ford Motor Company.) Nepretr\u017eit\u00e9 zlep\u0161ovanie<\/b> je mantrou \u0161t\u00edhlej v\u00fdroby. V praxi sa neust\u00e1le hodnotia nasleduj\u00face cesty:<\/p>\n

    \n
  1. Udr\u017eovanie \u00farovne z\u00e1sob surov\u00edn a hotov\u00fdch v\u00fdrobkov na minime<\/b>. \u0160t\u00edhla v\u00fdroba znamen\u00e1 minim\u00e1lne mno\u017estvo surov\u00edn na v\u00fdrobu tovaru a minim\u00e1lne mno\u017estvo u\u017e hotov\u00fdch v\u00fdrobkov, ktor\u00e9 \u010dakaj\u00fa na distrib\u00faciu objedn\u00e1vok alebo odoslanie.<\/li>\n
  2. Minimaliz\u00e1cia \u010dakac\u00edch objedn\u00e1vok<\/b>. Ide\u00e1lne je, ak sa prijat\u00e9 objedn\u00e1vky okam\u017eite dostan\u00fa do stavu dokon\u010den\u00fdch. K\u013e\u00fa\u010dovou metrikou \u0161t\u00edhlej v\u00fdroby bude v\u017edy \u010das od prijatia objedn\u00e1vky po dodanie.<\/li>\n
  3. Maximaliz\u00e1cia efektivity v\u00fdrobn\u00e9ho procesu<\/b>. Preorganizovanie procesov a zlep\u0161en\u00e1 automatiz\u00e1cia sa spojili s cie\u013eom v\u00fdroby tovaru \u010do najr\u00fdchlej\u0161ie. Ka\u017ed\u00e9 miesto v\u00fdroby na celom procese (rezanie, zv\u00e1ranie, mont\u00e1\u017e, testovanie at\u010f.) sa hodnot\u00ed z h\u013eadiska neefekt\u00edvnosti.<\/li>\n<\/ol>\n

    \nVo svete IT tradi\u010dn\u00e9 met\u00f3dy kask\u00e1dov\u00e9ho modelu v\u00fdvoja softv\u00e9ru u\u017e ust\u00fapili r\u00fdchlym iterat\u00edvnym met\u00f3dam, ako s\u00fa Agile<\/b>. R\u00fdchlos\u0165 bola bojov\u00fdm pokrikom, aj ke\u010f sa kvalita niekedy zhor\u0161ovala v honbe za r\u00fdchlym v\u00fdvojom a nasaden\u00edm. Takto sa aj cloud computing, konkr\u00e9tne Infrastructure-as-a-Service<\/b> (IaaS) a Platform-as-a-Service<\/b> (PaaS) sa osved\u010dili ako zrel\u00e9 rie\u0161enia v procesoch a infra\u0161trukt\u00fare IT.<\/p>\n

    Nakoniec, ned\u00e1vno sa za\u010dali objavova\u0165 n\u00e1stroje pre Continuous Integration<\/b> (CI). Predstavu o n\u00e1strojoch CI uviedol a predstavil Grady Booch u\u017e v roku 1991 vo svojej Metode Boocha.<\/p>\n

    2007-2008: Sklaman\u00fd Belgi\u010dan<\/h1>\n

    \nBelgick\u00fd konzultant, projektov\u00fd mana\u017e\u00e9r a praktik Agile Patrick Debois dostal poverenie od belgickej vl\u00e1dy, aby pomohol s migr\u00e1ciou d\u00e1tov\u00fdch centier. V konkr\u00e9tnych oblastiach sa zaoberal certifik\u00e1ciou a overovan\u00edm pripravenosti. Jeho povinnosti vy\u017eadovali, aby koordinoval \u010dinnosti a budoval vz\u0165ahy medzi t\u00edmami v\u00fdvoja softv\u00e9ru a prev\u00e1dzkov\u00fdmi t\u00edmami serverov<\/a>, datab\u00e1zami a sie\u0165ami. Jeho sklamanie z nedostatku s\u00fadr\u017enosti a m\u00farov, ktor\u00e9 rozdelili met\u00f3dy v\u00fdvoja a prev\u00e1dzky, v \u0148om vzbudilo hnev. T\u00fa\u017eba po lep\u0161om \u010doskoro priviedla Deboisa k akcii.
    \nV roku 2008 na konferencii o Agile v Toronte Andrew Shafer navrhol moderova\u0165 \u0161peci\u00e1lne usporiadan\u00e9 neform\u00e1lne stretnutie na diskusiu o t\u00e9meAgile-infrastrukt\u00fara<\/b>. A iba jedna osoba pri\u0161la prediskutova\u0165 t\u00e9mu: Patrick Debois. Ich diskusia a v\u00fdmena my\u0161lienok posunula koncept syst\u00e9mov\u00e9ho administrat\u00edvneho pr\u00edstupu pod\u013ea Agile. V tom istom roku Debois a Shafer vytvorili mierne \u00faspe\u0161n\u00fa skupinu Agile Systems Administrator na Google.<\/p>\n

    2009: Pr\u00edpad spolupr\u00e1ce Dev a Ops<\/h1>\n

    \nNa konferencii O'Reilly Velocity dvaja zamestnanci Flickru, senior viceprezident pre technick\u00e9 oper\u00e1cie John Allspaw a technick\u00fd riadite\u013e Paul Hammond, predstavili dnes u\u017e zn\u00e1my materi\u00e1l \u201e10 nasaden\u00ed denne: spolupr\u00e1ca Dev a Ops vo Flickr\u201c<\/b>. <\/p>\n

    Prezent\u00e1cia bola vo forme dramy, Allspaw a Hammond hrali zlo\u017eit\u00fa interakciu medzi z\u00e1stupcami Development a Operations po\u010das nasadzovania softv\u00e9ru s h\u013eadan\u00edm vinn\u00edkov a vz\u00e1jomn\u00fdmi obvineniami v duchu \u201eTo nie je m\u00f4j k\u00f3d, to s\u00fa tvoje po\u010d\u00edta\u010de!\u201c Ich prezent\u00e1cia potvrdila, \u017ee jedin\u00e9 rozumn\u00e9 rie\u0161enie je, aby \u010dinnos\u0165 v\u00fdvoja a nasadzovania softv\u00e9ru bola plynul\u00e1, transparentn\u00e1 a plne integrovan\u00e1. Postupom \u010dasu sa t\u00e1to prezent\u00e1cia stala legend\u00e1rnou a teraz je historicky pova\u017eovan\u00e1 za z\u00e1sadn\u00fd m\u00ed\u013enik, ke\u010f v IT priemysle vznikol dopyt po metodol\u00f3gii, ktor\u00e1 je dnes zn\u00e1ma ako DevOps.<\/p>\n

    2010: DevOps v Spojen\u00fdch \u0161t\u00e1toch americk\u00fdch<\/h1>\n

    \nS rast\u00facim po\u010dtom podporovate\u013eov sa konferencia DevOpsDays prv\u00fdkr\u00e1t konala v Spojen\u00fdch \u0161t\u00e1toch americk\u00fdch v Mountain View (Kalifornia) hne\u010f po ro\u010dnej konferencii Velocity. Presu\u0148me sa do roku 2018: napl\u00e1novan\u00fdch je viac ako 30 konferenci\u00ed DevOpsDays, vr\u00e1tane desiatok v Spojen\u00fdch \u0161t\u00e1toch.<\/p>\n

    2013: Projekt \u201eF\u00e9nix\u201c<\/h1>\n

    \nPre mnoh\u00fdch z n\u00e1s bol \u010fal\u0161\u00edm pozoruhodn\u00fdm momentom v hist\u00f3rii DevOps vydanie knihy \u201eProjekt Phoenix\u201c autorov Gina Kim, Kevina Beaera a Georgea Safforda. Tento rom\u00e1n rozpr\u00e1va pr\u00edbeh IT mana\u017e\u00e9ra, ktor\u00fd sa ocitol v bezv\u00fdchodiskovej situ\u00e1cii: bol poveren\u00fd z\u00e1chranou kriticky d\u00f4le\u017eit\u00e9ho projektu pre rozvoj elektronick\u00e9ho obchodu, ktor\u00fd sa nepodaril. Tajomn\u00fd mentor mana\u017e\u00e9ra \u2014 \u010dlen spr\u00e1vnej rady, nad\u0161enec met\u00f3d \u0161t\u00edhlej v\u00fdroby \u2014 nazna\u010duje hlavn\u00e9mu hrdinovi nov\u00e9 sp\u00f4soby ch\u00e1panie IT a v\u00fdvoja aplik\u00e1ci\u00ed, predv\u00eddaj\u00face koncept DevOps. Mimochodom, \u201eProjekt Phoenix\u201c n\u00e1s in\u0161piroval k nap\u00edsaniu knihy \u201ePrejdite na outsourcing, inak\u2026\u201c o podobnom pr\u00edbehu z biznisu, ke\u010f viceprezident pre softv\u00e9r vyu\u017e\u00edva DevOps pri v\u00fdvoji nov\u00e9ho ve\u013ek\u00e9ho produktu na outsourcingu.<\/p>\n

    DevOps pre bud\u00facnos\u0165<\/h1>\n

    \nStoj\u00ed za to op\u00edsa\u0165 DevOps sk\u00f4r ako cestu alebo mo\u017eno t\u00fa\u017ebu, ne\u017e ako kone\u010dn\u00fd cie\u013e. DevOps, podobne ako \u0161t\u00edhle riadenie, usiluje o neust\u00e1le zlep\u0161ovanie, zvy\u0161ovanie produktivity a efektivity a dokonca aj neust\u00e1le nasadzovanie. Automatizovan\u00e9 n\u00e1stroje na podporu DevOps sa na\u010falej vyv\u00edjaj\u00fa.<\/p>\n

    Ve\u013ea sa dosiahlo od vzniku DevOps v poslednom desa\u0165ro\u010d\u00ed a o\u010dak\u00e1vame, \u017ee uvid\u00edme e\u0161te viac v roku 2018 a v bud\u00facnosti.
