DevOps 的定義？
?
DevOps is… A cultural and professional movement, focused on how we
build and operate high velocity organisations, born from the experiences of its practitioners.

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.

DevOps 是⼀一組過程、⽅方法與系統的統稱，⽤用於促進開發（應⽤用程式/軟體⼯工程）、技術運營和質量保障（QA）部⾨門之間的溝通、協作與整合。它的出現是由於軟體⾏行業⽇日益清晰地認識到：為了按時交付軟體產品和服務，開發和運營⼯工作必須緊密合作。

Functional Silos Problematic
Functional silos abstract people away from the consequences of their actions.
In the example above, developers are abstracted away from the consequences of writing buggy code.

Why DevOps ?
來源: http://www.ithome.com.tw/news/87144
Why DevOps ?藉由將各開發階段自動化以及訊息公
開，幫助企業軟體研發相關部門，解決
傳統流程端對端（End to end）所產生
訊息不對稱，以及協作不順暢的問題，
並且自動化開發流程的每個階段，進而
提升軟體交付的速度。

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。
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。
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。
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。
‧ 改善團隊協作
‧ 幫助控管風險、成本，減少浪費
‧ 提升軟體品質
‧ 提升軟體迭代速度
