<h2>Definition</h2>
|
||||
<blockquote style="font-size:30px">
|
||||
“Le DevOps est un mouvement qui s’attaque au conflit existant structurellement entre le développement de logiciels et les opérations.<br>
|
||||
Ce conflit résulte d’objectifs et de motivations divergents.<br>
|
||||
Le DevOps améliore la collaboration entre les départements du développement et des opérations et rationalise l’ensemble de l’organisation.”
