  • インフラストラクチャ管理者は、パブリック・クラウドを採用することで、需要のないハードウェア資産や不要なハードウェア資産を、オンプレミスのデータセンターから削減または排除することができる。

  • 一部のオンプレミス・ワークロードは、法的要件、クラウド・アーキテクチャの非互換性、遅延が許されないデータへのニーズといった理由から、パブリック・クラウド展開にまったく適さない場合がある。

  • ハイブリッド・クラウド・モデルは、運用コストが低く、データ・セキュリティ上の懸念が少なく、より効率的な運用が可能であると考えられるため、魅力的な代替手段の1つである。


ハイブリッド・クラウドの潜在的利点を活用したいインフラストラクチャ/オペレーション (I&O) のリーダーは、以下を行う。

  • 業界のトレンドや、ベンダーから提案を受けた移行にまつわる技術的な問題ではなく、ビジネス・メリットに重点を置いて、クラウドとインフラストラクチャ・ホスティング戦略を擦り合わせる。

  • 各ワークロードの特性や、ワークロードを配置する可能性のある各ロケーションでのビジネス・インパクトを評価して、ワークロードごとに最適な選択肢は何かを判断する。

  • プライベート・クラウド・サービスとパブリック・クラウド・サービスを、統合型/並行型/相補型タスクをサポートできるよう最適に連携させて、ハイブリッド・クラウドの費用便益比を最大限に高める。
