  • 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、リソース不足を最大の懸念事項としており、他のオペレーティング・モデルを評価するようになっている。

  • オンプレミス上で稼働するアプリケーションに対応するサービスとしてのソリューション (XaaS) (Everything as a Serviceとも呼ばれる) の登場によって、これまで以上に選択肢が増えている。

  • 先行の設備投資 (Capex) によって製品選択と機能が制限され、企業の俊敏性が低下し、新たなケイパビリティの導入が限られてしまう恐れがある。



  • まずはビジネス目標を決定し、現行のデータセンター更改アプローチと、それと同等と想定されるサービスをしっかり比較することで、新しいサービス型の利用モデルが自社のコストと目標に整合しているかを確認する。

  • オンプレミスの従量制モデルとパブリック・クラウドのサービスを比較して、自社のアプリケーションに最適なものを選択する。両者を組み合わせることが最適なソリューションとなる場合が多い。

  • データセンター・インフラストラクチャのリプレースにおいて利用できるXaaSの選択肢の範囲を拡大することで、調達、所有、減価償却の限界を打開する。
