# Deployment { #deployment }

Deploying a **FastAPI** application is relatively easy.

## What Does Deployment Mean { #what-does-deployment-mean }

To **deploy** an application means to perform the necessary steps to make it **available to the users**.

## Deployment Concepts { #deployment-concepts }

Here you saw how to use multiple **workers** to **parallelize** the execution of the application, take advantage of **multiple cores** in the CPU, and be able to serve **more requests**.

### Decrypt the Request { #decrypt-the-request }

The TLS Termination Proxy would use the encryption agreed to **decrypt the request**, and would transmit the **plain (decrypted) HTTP request** to the process running the application (for example a process with Uvicorn running the FastAPI application).

# デプロイ { #deployment }

**FastAPI** アプリケーションのデプロイは比較的簡単です。

## デプロイとは { #what-does-deployment-mean }

アプリケーションを**デプロイ**するとは、**ユーザーが利用できるようにする**ために必要な手順を実行することを意味します。

**Web API** の場合、通常は **リモートマシン** 上に配置し、優れたパフォーマンス、安定性などを提供する **サーバープログラム** と組み合わせて、**ユーザー** が中断や問題なく効率的にアプリケーションへ**アクセス**できるようにします。

これは **開発** 段階とは対照的です。開発では、コードを常に変更し、壊しては直し、開発サーバーを停止したり再起動したりします。

## デプロイ戦略 { #deployment-strategies }

具体的なユースケースや使用するツールによって、いくつかの方法があります。

## 배포하기 { #deploy }

이제 **한 번의 명령**으로 앱을 배포합니다:

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...

✅ Deployment successful!

🐔 Ready the chicken! Your app is ready at https://myapp.fastapicloud.dev
```

</div>

이게 전부입니다! 이제 해당 URL에서 앱에 접근할 수 있습니다. ✨

## FastAPI Cloud 소개 { #about-fastapi-cloud }

- ✅ Tests with [Pytest](https://pytest.org).
- 📞 [Traefik](https://traefik.io) as a reverse proxy / load balancer.
- 🚢 Deployment instructions using Docker Compose, including how to set up a frontend Traefik proxy to handle automatic HTTPS certificates.

### 解密請求 { #decrypt-the-request }

TLS 終止代理會依照先前協商的方式**解密請求**，並將**純（已解密）的 HTTP 請求**轉交給運行應用的行程（例如以 Uvicorn 執行的 FastAPI 應用行程）。

<img src="/img/deployment/https/https05.drawio.svg">

### HTTP 回應 { #http-response }

應用會處理該請求，並將**純（未加密）的 HTTP 回應**送回 TLS 終止代理。

</div>

## Deploy { #deploy }

Now deploy your app, with **one command**:

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...

✅ Deployment successful!

🐔 Ready the chicken! Your app is ready at https://myapp.fastapicloud.dev
```

</div>

That's it! Now you can access your app at that URL. ✨
