以 ITIL 為基礎雲端運算服務品質評估機制之研究

Evaluation Mechanism for Service Quality of Cloud Computing Based on ITIL

隨著新的雲端運算服務和技術逐步進入市場，組織須不斷重新設計需求和重複評估，因此未來的評估工作應按照特定的準則加以規範。故本研究運用 Gowin's Vee 模型建立研究的流程，在文獻端透過文獻探討相關服務品質量表，以 ITIL 作為研究基礎，發展與建構雲端運算服務品質評估機制雛形；實證端則採用德爾菲專家問卷萃取適合衡量雲端運算品質服務項目，因此修正後的雲端運算服務品質評估機制包括有五大模組、19 個流程與 44 個衡量項目，最後輔以層級分析法確認衡量項目間相對權重後，建構適合衡量不同供應商之雲端運算服務品質評估機制。這些結果可協助不同雲端運算服務供應商定義清楚自身市場定位及強化競爭優勢，同時更貼近不同雲端運算服務使用者 的需求。

As new cloud computing services and technologies penetrate the market gradually, and organizations should constantly redesign and reevaluate demands. Therefore, future assessment should be regulated according to specific criteria. This study adopts Gowin's Vee Model to establish the study process. Literature is employed to investigate relative service quality scales. With Information Technology Infrastructure Library (ITIL) as the research foundation, the embryo of cloud computing service quality assessment mechanism is developed and established. For verification, Delphi method is employed to determine the services suitable for measuring the quality of cloud computing. Therefore, the assessment mechanism of cloud computing service quality modified in this study includes five modules, 19 processes, and 44 measurement items. Lastly, after Analytic Hierarchy Process is adopted to confirm the relative weight of measurement items for diverse cloud computing service suppliers. The result can not only help different cloud computing service suppliers clearly define their positions in the market and enhance their competitive advantages, but can also meet the demands and requirements of users.
