\nNejprve, co je to DevOps?

A to je v\u0161e.<\/p>\n

Dob\u0159e, ale co vlastn\u011b toto zkratka znamen\u00e1? Znamen\u00e1 to, \u017ee tradi\u010dn\u011b v\u00fdvoj\u00e1\u0159i (lid\u00e9, kte\u0159\u00ed vytv\u00e1\u0159ej\u00ed software) v sv\u00e9 pr\u00e1ci byli motivov\u00e1ni podn\u011bty, kter\u00e9 se v\u00fdznamn\u011b li\u0161ily od podn\u011bt\u016f operac\u00ed (nebo lid\u00ed, kte\u0159\u00ed spravuj\u00ed software). Nap\u0159\u00edklad jako v\u00fdvoj\u00e1\u0159 chci co nejrychleji vytvo\u0159it co nejv\u00edce nov\u00fdch funkc\u00ed. Nakonec, to je m\u00e1 pr\u00e1ce a to klienti po\u017eaduj\u00ed!

DevOps se sna\u017e\u00ed slou\u010dit v\u00fdvoj a operace (integraci a automatizaci) do jedn\u00e9 skupiny. My\u0161lenka spo\u010d\u00edv\u00e1 v tom, \u017ee nyn\u00ed jedna skupina ponese jak bolest, tak odpov\u011bdnost (a pravd\u011bpodobn\u011b i odm\u011bnu) za vytv\u00e1\u0159en\u00ed, nasazen\u00ed a generov\u00e1n\u00ed p\u0159\u00edjm\u016f ze softwaru zam\u011b\u0159en\u00e9ho na z\u00e1kazn\u00edka.<\/p>\n

Samoz\u0159ejm\u011b, z technick\u00e9ho hlediska maj\u00ed pravdu, ale, jak to \u010dasto b\u00fdv\u00e1, tento term\u00edn se vyvinul nad r\u00e1mec sv\u00e9ho p\u016fvodn\u00edho v\u00fdznamu.
