準上線網站（staging site）也會被用來讓一小部分參訪者觀看最新的部署版本—如果有
臭蟲或效能衰退被發現，它就只會影響少部分的參訪者，這個版本就會快速地被撤除，
讓部署缺陷不致於造成那麼大的代價與問題。
Sentry 被用來記錄及診斷 Python 的追蹤堆疊。

一些建議
使用良好的工具來追蹤記錄你所開發之軟體的有效性，並且在一開始就抱持著超級務實
的態度，確實是一件非常重要的事。新興公司持續改變，工程技術也逐步演進︰你從高
度探索性的階段開始，不斷建構原型（prototype），刪除程式碼，直到你探勘到金礦，
接著，你開始深入，改善程式碼、效能等等。在此之前，這全然關係到快速迭代（quick
iteration）以及良好的監控∕分析。我想這是相當標準的建議，一再地被重述過，但我
認為很多人並不瞭解這究竟有多重要。
我不認為技術在現今的影響有那麼大，因此，使用任何對你有效的工具吧。不過，在移
動到 AppEngine 或 Heroku 之類的主機代管環境之前，我會三思而後行。
