分享於 C.C. Agile #37 (2015.9.24) DevOps 一詞自 2009 年出現之後，現在已經是全球熱門的重要關鍵字，你可以看到 Everyone is “selling, doing, hiring DevOps”，顯然這已是無法阻擋的趨勢！這次有榮幸能在 C.C. Agile 社群中再次與大家聊一聊什麼是 DevOps？因此有別於過去的簡報《摩登開發團隊的 DevOps 之道》，重新補充了一些新的內容，希望能幫助大家更認識 DevOps，不被潮流名詞所迷惑。

- 19. DevOps is… A cultural and professional movement, focused on how we build and operate high velocity organisations, born from the experiences of its practitioners. ! 來源: https://www.chef.io/solutions/devops/ Chef
- 20. DevOps represents a change in IT culture, focusing on rapid IT service delivery through the adoption of agile, lean practices in the context of a system-oriented approach. DevOps emphasizes people (and culture), and seeks to improve collaboration between operations and development teams. DevOps implementations utilize technology — especially automation tools that can leverage an increasingly programmable and dynamic infrastructure from a life cycle perspective. 來源: http://www.gartner.com/it-glossary/devops/ Gartner

- 68. 來源: http://www.ithome.com.tw/news/87144 Why DevOps ? CIO在雲端時代必須聚焦在總體商業的結 果，了解究竟IT提供企業什麼價值，這包 含三個要點，應用程式部署的速度、衡量 風險、控制成本。如果守著過去開發及營 運模式，對於以上提及的三點將失去競爭 力，也因為如此，傳統的方式必須改變。
- 69. 來源: http://www.ithome.com.tw/news/87144 Why DevOps ? 就如同精實開發的精隨，減少不 必要的浪費以及重複性的程序， 做到剛好符合需求。
- 70. 來源: http://www.ithome.com.tw/news/87144 Why DevOps ? 因此可以減少錯誤發生，開發人員也可以 專注在產生更有品質的程式碼，避免之後 不停的修補程式碼，有更多心力去做一些 有趣的事，我們也從一些客戶案例看到， 開發人員不只更有生產力，他們也更快樂 了，而且良好軟體讓維運更容易。
- 71. 來源: http://www.ithome.com.tw/news/87144 Why DevOps ? 我們有一些來自客戶的數據，軟體測試 可以減少90％的時間，版本釋出和部署 的頻率可以大幅提升。實際案例顯示， 過去要兩年才能釋出1個新產品，導入 DevOps開發方法後，一年半可以發布 18個成品。
