Included in Full Research


  • レガシー/オンプレミスをターゲットとしているベンダーは、従量制モデルを採用してクラウドに対応している。従量制モデルは名目上、使用量に応じたクラウドライクな料金体系を提供するが、パブリック・クラウド・ソリューションとまったく同じというわけではない。従量制ソリューションは、CAPEX (設備投資) による調達方法に取って代わる、資産の資金調達/管理機能を備えており、ハイブリッド・クラウドITオペレーションへの移行を実現する。

  • オンプレミスのデータセンター・インフラストラクチャ向け従量制モデルは、資産コストを資産価値に整合させるほか、資産の耐用年数全体にわたってインフラストラクチャの継続的な利用レベルを高めることで、全体的な総資産利益率 (ROA) を向上させる。

  • オンプレミスのデータセンター・インフラストラクチャ向け従量制モデルには、AIOps (Artificial Intelligence for IT Operations) ツールや、オンプレミスの管理/サポートを強化する機能が含まれているため、IT管理コスト全般を削減できる。


データセンター・インフラストラクチャを担当する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。

  • 高額な資金調達、過剰な先行投資、クラウド・ネイティブ・インフラストラクチャの利用に関する制約事項を回避するために、ハイブリッド・クラウドITプラットフォームに備わる従量制プランを選択する。

  • 資産中心のオペレーション手法/プロセス/IT予算支出を、使用量に応じた料金体系 (PFU:Pay for Use) のソリューションに置き換えて資産の利用価値を保つことで、ハードウェア資産の非効率的な利用を回避する。

  • 資産の最適な利用を維持できるライフサイクル管理機能を提供するプラットフォーム・ベンダーと連携し、ハードウェアの管理/サポート/保守からの脱却を計画する。
