Google Cloud Platformに関する作業などがブラウザから簡単に行うことができるCloud Shell。
外出先等でちょっと用事があるときに非常に便利ですよね。
今回はこのCloud ShellのベンチマークをUnixBenchで採ってみました。
ところで、Cloud ShellはGCEのg1-smallらしいです。（ブースト時はn1-standard-1)
前はg1-smallではなくf1-microだった気がするんですけど、気のせいですかね？
特徴
・Compute Engine での一時的な仮想マシン インスタンス
・ウェブブラウザからインスタンスへのコマンドライン アクセス
・組み込みのコードエディタ ベータ版
・5 GB の永続ディスク ストレージ
・プレインストールされた Google Cloud SDK とその他のツール
・Java、Go、Python、Node.js、PHP、Ruby、.NET への言語対応
・ウェブ プレビュー機能
・GCP Console のプロジェクトとリソースに対するアクセスのビルトイン承認
https://cloud.google.com/shell/docs/features
通常はCloud Shellを開いた時、g1-smallがプロビジョニングされます。
ブーストモードを有効にした場合はn1-standard-1としてプロビジョニングされます。
また、実は週単位で使用できる時間に制限があるようです。

System Benchmarks Index Score 330.4最後に
Index Scoreをざっと見ると、Cloud Shellはg1-smallがプロビジョニングされているとは言えだいぶ制限されているように見えます。
通常時はf1-microより少しいいぐらいで、ブースト時にg1-small相当のような感じでしょうか。
Cloud Shellは無料で使えるので勿論十分すぎるといえば十分すぎますね。
