# Deployments Concepts { #deployments-concepts }

When deploying a **FastAPI** application, or actually, any type of web API, there are several concepts that you probably care about, and using them you can find the **most appropriate** way to **deploy your application**.

Some of the important concepts are:

* Security - HTTPS
* Running on startup
* Restarts
* Replication (the number of processes running)
* Memory
* Previous steps before starting

## Custom Headers { #custom-headers }

Keep in mind that custom proprietary headers can be added <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">using the 'X-' prefix</a>.

    /**
     * The name of the request header.
     */
    public String name;

    /**
     * The value of the request header.
     */
    public String value;

    /**
     * The web configuration ID associated with this request header.
     */
    public String webConfigId;

    /**
     * The user who created this request header.
     */
    public String createdBy;

# WebSockets

Você pode usar <a href="https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API" class="external-link" target="_blank">WebSockets</a> com **FastAPI**.

## Instalando `WebSockets`

Garanta que você criou um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, o ativou e instalou o `websockets`:

<div class="termy">

```console
$ pip install websockets

---> 100%
```

* **深度學習**: 這是機器學習的子領域，同樣適用。只不過這不僅僅是一張數字表格，而是大量的數據集合，並且在很多情況下，你會使用特殊的處理器來構建或使用這些模型。

### 並行 + 平行: Web + 機器學習

使用 **FastAPI**，你可以利用並行的優勢，這在 Web 開發中非常常見（這也是 NodeJS 的最大吸引力）。

但你也可以利用平行與多行程 (multiprocessing)（讓多個行程同時運行） 的優勢來處理機器學習系統中的 **CPU 密集型**工作。

這一點，再加上 Python 是 **資料科學**、機器學習，尤其是深度學習的主要語言，讓 **FastAPI** 成為資料科學/機器學習 Web API 和應用程式（以及許多其他應用程式）的絕佳選擇。

# ボディ - 更新

## `PUT`による置換での更新

項目を更新するには<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PUT" class="external-link" target="_blank">HTTPの`PUT`</a>操作を使用することができます。

`jsonable_encoder`を用いて、入力データをJSON形式で保存できるデータに変換することができます（例：NoSQLデータベース）。例えば、`datetime`を`str`に変換します。

{* ../../docs_src/body_updates/tutorial001.py hl[30,31,32,33,34,35] *}

既存のデータを置き換えるべきデータを受け取るために`PUT`は使用されます。

### 置換についての注意

つまり、`PUT`を使用して以下のボディで項目`bar`を更新したい場合は:
