雲端的另一個主要好處是基礎結構可以靈活地實例化。雲端可讓每位開發者建立自己的
測試環境，或執行大規模測試（但是要注意成本！）。
開發者無法（或不該）在雲端做每一件事
因為雲端可讓人用程式操作多數的基礎設施，開發者越來越喜歡在交付軟
體的運維面承擔更多責任。對小規模的組織或初創企業來說，這種做法或
許是有幫助的，可讓小型開發團隊自給自足，並快速行動。但是這也代表
開發者的工作更繁重，或必須學習越來越多新技術（有時不屬於他們的專
業知識或超出他們的舒適圈），或對開發與運維角色之間固有的折衝與摩
擦視而不見。這可能會造成個人或團隊精疲力竭，或在生產環境產生許多
app 運維方面的問題。你要不計代價避免這種情況。

在雲端環境實施 CD 通常比傳統基礎設施平台簡單，因為 CD 在很大程度上是與雲端技
術共同發展的（反之亦然）。虛擬化與公用雲端供應商提供了 API 與 SDK，這意味著環
境（測試與 QA 等等）的製作與複製容易得多。除了之前談過的，在傳統基礎設施實施
CD 的步驟之外，下面的準則也適用於雲端：
• 分析哪種雲端部署方案最適合你目前的專案。AWS、GCP 與 Azure 等大型雲端供應
商都提供多種雲端平台，包括 AWS ECS 與 Azure AKS 等容器（稍後說明）、AWS
Elastic Beanstalk 與 Azure App Service 等 PaaS 商品，以及 IaaS 構建元素，包含計
算、儲存器與網路。
• 把重心放在建立交付 app 的 CD
