雲端運算是一種可提供企業快速有彈性，並且可依量計價的資訊服務新模式，不 但替企業降低IT 上的投資成本，同時提供企業更好的服務，企業亦可利用雲端運算 的特性，加強企業核心競爭力，並且發展創新業務服務。但是企業對於導入雲端運算 的應用，仍存有諸多疑點與障礙，也相對阻礙了雲端運算在企業內部的應用發展。本 研究的目的即是探討雲端運算之主要問題與疑慮，並試圖找出其導入的關建影響構 面，並建構出導入雲端運算的策略模式，提供企業參考之依據。本研究主要透過文獻探討，歸納出主要影響構面為「成本效益」、「資訊安全」、「服務模式」、「部署 模式」以及「組織因素」，並同時訪問專家的意見，結合文獻探討與問卷調查，推導 出策略規劃模式，在導入雲端運算之執行計劃，建議企業需依序評估九個要項：評估 並選擇適合部署於雲端之應用、決定雲端部署模式、選擇雲端服務模式、選擇雲端供 應商、評估成本與投資報酬、調整IT 組織架構、擬訂測試計劃、試做前導專案、導 入雲端運算應用，最後並依不同情境，例如企業規模，提供適當的企業導入雲端運算 策略模式，以供企業參考運用。

Cloud computing is a new model of information service that provides efficiency, flexibility, and measured services to businesses. It not only helps to reduce investment cost on information technology but also provides a better service for businesses. Businesses may also utilize the cloud computing to enhance core competence to develop innovative business model. However, there are a number of questions and obstacles for businesses to implement the applications of cloud computing. Therefore, it interferes with businesses to develop cloud computing applications. The objectives of this study aim to investigate the main issues, find out key aspects, and build up the strategic models to implement cloud computing for businesses. The main aspects of conclusion are “cost benefit”, “information security”, “service models”, “deployment models” and “organization” by reviewing the literatures on cloud computing. The strategic planning models come from literature review, questionnaire survey, and interview with experts. Businesses are recommended to evaluate nine major elements in sequence when conducting the implementation of cloud computing. These nine elements include evaluate and select appropriate applications to be deployed in cloud computing, decide deployment models of cloud computing, select service models of cloud computing, select service provider of cloud computing, evaluate cost and return on investment reorganize IT structure, draw up testing plan, trial run pilot implementation, implement applications of cloud computing. Lastly, appropriate strategic models based on different scenarios are presented for businesses to implement cloud computing.
