DigitalOcean、Vultr、Linode、Hetzner の仮想サーバーをテストします。 人的被害: 0.0

以前の記事で結果を紹介しました 安価な仮想サーバーをテストする さまざまな RuNet ホスティング会社から。 すべてのコメンテーターとプライベートメッセージでフィードバックを書いてくれた人々に感謝します。

今回は、有名企業と大企業の仮想サーバーをテストした結果を紹介したいと思います。 DigitalOcean, Vultr, Linodeの и ヘッツナー。 利用可能なすべての場所に対して 38 のテストを実施しました。

DigitalOcean、Vultr、Linode、Hetzner の仮想サーバーをテストします。 人的被害: 0.0

今回の仮想サーバーの特性は非常に近いですが、テスト形式はあまり客観的ではなく、測定値は非常に相対的なものであるため、結果はある程度の皮肉を込めて見る必要があることを思い出してください。

前回と同様に、テストは Debian 9 で実行される unixbench、dd、fio、speedtest を使用して実行されましたが、パラメーターは変更されませんでした (64 つの dd テスト: 1K および XNUMXM のブロック内、XNUMX つの fio テスト: ランダム読み取り、ランダム直接読み取り) 、ランダムモード書き込みおよびランダム直接書き込み)。

Linode と Vultr が最も安定した結果を示しているように思えました。 Hetznerは少し遅れていますが、少し異なる価格カテゴリーに属しています。 DigitalOcean はいくつかのテスト (特に Unixbench) で他のホスティング会社よりも劣っていましたが、全体的にはこのホスティング会社がとても気に入っています。
