ここまでのドキュメントのチュートリアルでは、おそらくUvicornのような**サーバープログラム**を**単一のプロセス**で実行しています。

アプリケーションをデプロイする際には、**複数のコア**を利用し、そしてより多くのリクエストを処理できるようにするために、プロセスの**レプリケーション**を持つことを望むでしょう。

前のチャプターである[デプロイメントのコンセプト](concepts.md){.internal-link target=_blank}にて見てきたように、有効な戦略がいくつかあります。

ここでは<a href="https://gunicorn.org/" class="external-link" target="_blank">**Gunicorn**</a>が**Uvicornのワーカー・プロセス**を管理する場合の使い方について紹介していきます。
