Included in Full Research


  • インフラストラクチャ/オペレーション (I&O) のリーダーの多くは、テクノロジの急速な変化に対応できていない。

  • ハイパースケーラーが、ハイブリッド・クラウドもしくは分散クラウドのソリューションの一部として、オンプレミス・サービスを展開し始めている。

  • ハイパーコンバージド・インフラストラクチャ (HCI) に含まれる、ハイブリッド・クラウドを実現するテクノロジや手法は、ユーザー企業においては必ずしも認識されていない。また、クラウド・デリバリに即した従量課金モデルに対するユーザー企業理解が不足しているケースがある。

  • IT運用部門/子会社は、レガシーなオンプレミス中心の運用に手間を取られている。

  • IBM、NECを除くメインフレーム・ベンダーは基本的に撤退の方向であり、レガシー・マイグレーションが再びユーザーの関心を集めている。



  • リサーチノートの図1を参考にオンプレミスの棚卸しを行い、不満や無駄、潜在的リスクを特定し、ビジネス価値によって仕分けする

  • Newオンプレミス (クラウド・ネイティブの要素を取り入れた新しいオンプレミス) への理解を深めて備えを強化し、ハイパースケーラーならびにクラウド・ネイティブのテクノロジと実践のトレンドを学び、自社システムの将来を考察する。

  • HCIにおけるクラウド・ネイティブの特性に着目し、最新のサービスを提供する基盤としてのインフラ・ソフトウェアの進化や手法、運用スキルについてベンダーに提案を求める。

  • DevOpsおよびハイブリッドITオペレーションを考慮した自動化やセルフサービス化、従量課金モデルの採用、ビジネスKPIとのダッシュボード連携によってオンプレミスとしての価値を高める。

  • メインフレーム・マイグレーションに関して、コスト最適化に配慮していないベンダーやシステム・インテグレーターの提案をうのみにしない。
