こんにちは。池田です。はたしてサンタさんからEcho Plus購入の招待メールは届くのでしょうか。

はじめに

リザーブドインスタンス(RI)について以前、(こちらの記事)にてざっくりとご紹介しましたが、今回は具体的にどれくらいお得なのか一覧表でご紹介します。
RDSについての比較記事はこちらをご覧ください。
Amazon RedshiftおよびAmazon ElastiCacheについての比較記事はこちらをご覧ください。

非常に数が多いので、本記事ではEC2インスタンスのうち弊社ユーザー様に多くご利用いただいている&お問い合わせをいただいている、LinuxおよびRHELとWindowsの3プラットフォームにおいて、スタンダードRI、東京リージョン、1年全前払いという条件で購入する場合の情報をオンデマンド料金と比較するかたちで掲載します。

    さいごに

    いかがでしたでしょうか。プラットフォームを3種に絞ったのに豊富なインスタンスタイプのおかげで、これだけのボリュームがあったのには改めて驚きました。
    最も割引率が高いのはd2ファミリーの50%前後でしたが、1年間稼働させ続ける前提のあるインスタンスはRIを利用することでずいぶんと費用の削減が可能であることがお分りいただけたのではないでしょうか。
    また、RIの利用に加えてクラスメソッドメンバーズをご利用いただくと更なる費用削減と、様々な安心サービスまでご利用いただけます!
