Podle va\u0161eho pohledu, DevOps si letos p\u0159ip\u00ed\u0161e sv\u00e9 dev\u00e1t\u00e9 nebo des\u00e1t\u00e9 v\u00fdro\u010d\u00ed.

Ka\u017ed\u00e1 slo\u017eka tohoto hodnocen\u00ed od t\u00e9 doby vzrostla.

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

    \nBelgi\u010dan Patrick Debois, konzultant, projektov\u00fd mana\u017eer a praktik Agile, p\u0159ijal jmenov\u00e1n\u00ed od belgick\u00e9 vl\u00e1dy, aby pomohl s migrac\u00ed datov\u00fdch center. Zvl\u00e1\u0161t\u011b se zam\u011b\u0159il na certifikaci a ov\u011b\u0159ov\u00e1n\u00ed p\u0159ipravenosti. Jeho povinnosti zahrnovaly koordinaci aktivit a budov\u00e1n\u00ed vztah\u016f mezi t\u00fdmy v\u00fdvoje softwaru a provozn\u00edmi t\u00fdmy, servery<\/a>datov\u00fdmi centry a s\u00edt\u011bmi. Jeho zklam\u00e1n\u00ed z nedostatku soudr\u017enosti a zd\u00ed odd\u011bluj\u00edc\u00edch metody v\u00fdvoje a provozu v n\u011bm vzbudilo frustraci. Touha po zlep\u0161en\u00ed brzy vedla Deboise k \u010dinu.
    \nV roce 2008 na konferenci Agile v Torontu navrhl Andrew Shafer moderovat speci\u00e1ln\u011b uspo\u0159\u00e1dan\u00e9 neform\u00e1ln\u00ed setk\u00e1n\u00ed k t\u00e9matu \"Agiln\u00ed infrastruktura<\/b>\". A na toto setk\u00e1n\u00ed p\u0159i\u0161el pouze jedin\u00fd \u010dlov\u011bk, Patrick Debois. Jejich diskuze a v\u00fdm\u011bna my\u0161lenek posunuly koncept syst\u00e9mov\u00e9ho administrativn\u00edho \u0159\u00edzen\u00ed podle Agile. Ve stejn\u00e9m roce Debois a Shafer vytvo\u0159ili m\u00edrn\u011b \u00fasp\u011b\u0161nou skupinu Agile Systems Administrator na Googlu.<\/p>\n

    2009: P\u0159\u00edpad spolupr\u00e1ce Dev a Ops<\/h1>\n

    \nNa konferenci O'Reilly Velocity p\u0159edstavili dva zam\u011bstnanci Flickru, senior viceprezident pro technick\u00e9 operace John Allspaw a technick\u00fd \u0159editel Paul Hammond, dnes ji\u017e slavnou prezentaci \u201e10 nasazen\u00ed za den: spolupr\u00e1ce Dev a Ops ve Flickr\u201c<\/b>. <\/p>\n

S \u010dasem se tato prezentace stala legend\u00e1rn\u00ed a nyn\u00ed je historicky pova\u017eov\u00e1na za kl\u00ed\u010dov\u00fd mezn\u00edk, kdy v IT pr\u016fmyslu vznikl po\u017eadavek na metodologii, kter\u00e1 je dnes zn\u00e1m\u00e1 jako DevOps.<\/p>\n

    \nS rostouc\u00edm po\u010dtem p\u0159\u00edznivc\u016f se konference DevOpsDays poprv\u00e9 konala v USA v Mountain View (Kalifornie) hned po ka\u017edoro\u010dn\u00ed konferenci Velocity. P\u0159enesme se do roku 2018: je napl\u00e1nov\u00e1no v\u00edce ne\u017e 30 konferenc\u00ed DevOpsDays, v\u010detn\u011b des\u00edtek v USA.<\/p>\n

    2013: Projekt Phoenix<\/h1>\n

Mimochodem, \u201eProjekt Phoenix\u201c n\u00e1s inspiroval napsat knihu \u201eP\u0159ejdi na outsourcing, jinak\u2026\u201c o podobn\u00e9m p\u0159\u00edb\u011bhu z byznysu, kdy viceprezident pro software vyu\u017e\u00edv\u00e1 DevOps b\u011bhem v\u00fdvoje nov\u00e9ho velk\u00e9ho produktu na outsourcingu.<\/p>\n

    \nM\u011blo by se sp\u00ed\u0161e ne\u017e jako c\u00edlov\u00fd bod popsat DevOps jako cestu nebo mo\u017en\u00e1 aspiraci. DevOps, stejn\u011b jako \u0161t\u00edhl\u00e9 podnik\u00e1n\u00ed, usiluje o neust\u00e1l\u00e9 zlep\u0161ov\u00e1n\u00ed, zvy\u0161ov\u00e1n\u00ed produktivity a efektivity a dokonce i o nep\u0159etr\u017eit\u00e9 nasazen\u00ed.
