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

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。

sight, hurrying down it.  There was not a moment to be lost:
away went Alice like the wind, and was just in time to hear it
say, as it turned a corner, `Oh my ears and whiskers, how late
it's getting!'  She was close behind it when she turned the
corner, but the Rabbit was no longer to be seen:  she found
herself in a long, low hall, which was lit up by a row of lamps
hanging from the roof.

### Autres formes de code asynchrone

L'utilisation d'`async` et `await` est relativement nouvelle dans ce langage.

Mais cela rend la programmation asynchrone bien plus simple.

Aber irgendwann gab es keine andere Möglichkeit, als etwas zu schaffen, das all diese Funktionen bereitstellte, die besten Ideen früherer Tools aufnahm und diese auf die bestmögliche Weise kombinierte, wobei Sprachfunktionen verwendet wurden, die vorher noch nicht einmal verfügbar waren (Python 3.6+ Typhinweise).

### Andere Formen von asynchronem Code

Diese Art der Verwendung von `async` und `await` ist in der Sprache relativ neu.

Aber sie erleichtert die Arbeit mit asynchronem Code erheblich.

### CLI Improvements

- Added `kubeadm upgrade node`. This command can be used to upgrade both secondary control-plane nodes and worker nodes. The `kubeadm upgrade node config` and `kubeadm upgrade node experimental-control-plane` commands are now deprecated.
