// A tensorflow.ServerDef specifies remote workers (in addition to the current
// workers name). Operations created in this context can then be executed on
// any of these remote workers by setting an appropriate device.
//
// If the following is set, all servers identified by the
// ServerDef must be up when the context is created.

しかし、多くの場合、複数のワーカー・プロセスを同時に実行したいと考えるでしょう。

### 複数のプロセス - Worker { #multiple-processes-workers }

クライアントの数が単一のプロセスで処理できる数を超えており（たとえば仮想マシンがそれほど大きくない場合）、かつサーバーの CPU に**複数のコア**がある場合、同じアプリケーションで同時に**複数のプロセス**を実行させ、すべてのリクエストを分散させることができます。

同じAPIプログラムの**複数のプロセス**を実行する場合、それらは一般的に**Worker／ワーカー**と呼ばれます。

### ワーカー・プロセス と ポート { #worker-processes-and-ports }

Ich finde, `Union[SomeType, None]` ist expliziter in dem, was es bedeutet.

Es geht nur um Wörter und Namen. Aber diese Wörter können beeinflussen, wie Sie und Ihr Team über den Code denken.

Als Beispiel nehmen wir diese Funktion:

```python
from typing import Optional


def say_hi(name: Optional[str]):
