鑒於在IT技術越來越複雜且產品生命週期越來越短的今日。身為IT從業人員與專業經理人，在面臨如何評估並且採用新科技，並確保其在導入後能滿足並符合商業流程需求的決定上，是一個很大的挑戰。其中最典型的難題，就是以雲端科技取代傳統機房的議題上，在IT業界已經被討論很久而沒有定論。有鑑於此，為了能夠找強化業主信心、增加決策效率、縮短評估流程並能符合企業或營運需求，本研究透過專家訪談與層級分析法(Analytic Hierarchy Process, AHP)所得到的評估因子順序與權重來提出一套評估方法。根據研究結果，對於評估雲端科技之因素權重與順序為：營運持續性(0.2713)、資訊安全(0.2430)，商業目標一致性(0.2223)，服務可得性(0.0945)，成本效益(0.0901)，以及技術效益(0.0787)在採用雲端科技取代傳統機房的議題上，結果說明雲端科技是可行的，且建議最好的採用方式是：對內部系統進行分類與重要性排序後，以階段性的方式逐步將適合系統由傳統機房移轉到雲端平台，並保留營運必要或是資料存取量高的系統於傳統機房內。並持續投資網路與資訊安全設備，來維持穩定與可靠的網路連線，以支持企業對雲端平台的存取能力。

As the Information Technology (IT) advances and the life cycle of IT product is shortening in each day, it becomes a great challenge for IT practitioners and professional managers to evaluate the new technology and to ensure it can satisfy business needs. A typical dilemma for those IT professionals is whether to replace premise data centers with cloud computing technology. This issue has been long discussed without clear conclusion.

This study seeks to find an evaluation approach by using weighted assessment factors via AHP (Analytic Hierarchy Process) and interviewing IT professionals. We believe through the process, this study can strengthen corporate owners’ confidence, improve decision-making efficiency, shorten evaluation process and meet business or operation requirement. The study found the weighted factors to evaluate cloud platforms in sequence are: business continuity (0.2713), information security (0.2430), business goal consistency (0.2223), service availability (0.0945), cost effectiveness (0.0901) and technical benefits (0.0787).

It has been found by the study that cloud technology provides a solution to this issue and we recommend the best practice is to classify and prioritize internal systems, gradually transfer them from data center to suitable cloud platforms, consider hosting operational essentials and data access resource intensive systems in on premise data center, and provides sustaining investment on network and information security appliances to maintain a stable and reliable network connectivity to support cloud platforms accessibility.
