    * 上で述べたように、特定のIPとポートでリッスンできるプロセスは1つだけです。
    * これは、同じTLS Termination Proxyが証明書の更新処理も行う場合に非常に便利な理由の1つです。
    * そうでなければ、TLS Termination Proxyを一時的に停止し、証明書を取得するために更新プログラムを起動し、TLS Termination Proxyで証明書を設定し、TLS Termination Proxyを再起動しなければならないかもしれません。TLS Termination Proxyが停止している間はアプリが利用できなくなるため、これは理想的ではありません。


アプリを提供しながらこのような更新処理を行うことは、アプリケーション・サーバー（Uvicornなど）でTLS証明書を直接使用するのではなく、TLS Termination Proxyを使用して**HTTPSを処理する別のシステム**を用意したくなる主な理由の1つです。
