# 部署概念 { #deployments-concepts }

當你要部署一個 FastAPI 應用，或其實任何類型的 Web API 時，有幾個你可能在意的概念。掌握這些概念後，你就能找出最適合部署你應用的方式。

一些重要的概念包括：

- 安全性 - HTTPS
- 開機自動執行
- 重新啟動
- 複本（執行中的行程數量）
- 記憶體
- 啟動前的前置步驟

我們將看看它們如何影響部署。

最終目標是能夠以安全、避免中斷，並盡可能高效使用運算資源（例如遠端伺服器／虛擬機）的方式來服務你的 API 用戶端。🚀

我會在這裡多介紹一些這些觀念，希望能幫你建立必要的直覺，讓你能在非常不同、甚至尚未出現的未來環境中決定要如何部署你的 API。

在思考這些概念之後，你將能夠評估與設計最適合部署你自己 API 的方式。

在接下來的章節，我會提供更具體的部署 FastAPI 應用的食譜。

* Deployment will stop adding pod-template-hash labels/selector to ReplicaSets and Pods it adopts. Resources created by Deployments are not affected (will still have pod-template-hash labels/selector).  ([#61615](https://github.com/kubernetes/kubernetes/pull/61615), [@janetkuo](https://github.com/janetkuo))
