隨著資訊科技的進步，雲端運算相關的各種研究發展，成為一個熱門趨勢。在最近這幾年學術期刊及報章雜誌，有各種相關的研究報告，政府相關單位也成立了對應的研發機構。然而，這些研究大部份專注在基礎架構或平台方面。例如：在基礎架構(IaaS)方面有工業技術研究院的『雲端運算行動運用科技中心』，資策會創新應用服務研究所的『雲端服務技術中心』，以及中華電信所推出的『hiCloud』雲端運算服務。在企業界有騰雲科技從事雲端運算『基礎架構』及『軟體開發平台』(PaaS)兩方面的開發。針對軟體服務(SaaS)的相關研究，資策會與10 家國內企業共同參與合作，計畫推出教育雲、製造雲、資訊雲、貿易雲、醫療雲、品管雲、培訓雲、客服雲和實習雲，共9項雲端服務。只不過目前還在初期階段，沒有大量的運用或成功案例。

本研究從企業需求的角度，探討當企業引進雲端運算軟體服務(SaaS)時對企業的影響。先以資源基礎分析方法來研究，引進雲端運算軟體服務前、後，對於企業競爭力之影響變化。接著再針對企業之資訊委外策略、成本結構及資料安全技術等構面，進行關鍵因素之研究與探討。就如大家所熟知的，雲端運算在成本議題上具有超過大多數人所認知的絕對優勢。

With advances in information technology, various cloud computing related research and development has become a hot trend. Except the vast amount of studies and reports appearing in local magazines and newspapers, government agencies have also set up corresponding R & D projects. However, most of these studies focus on the infrastructure or platform level of the cloud. For example, the projects for Infrastructure as a Service (IaaS) include the Cloud Computing Center for Mobile Application at Industrial Technology Research Institute (ITRI), the Cloud Service and Technology Center at Information Industry Institute (III) and the already launched “hiCloud” at Chunghwa Telecom Corporation. In the business side, there is TCloud Computing that does the development of both "Infrastructure" and "Platform as a Service" (PaaS). As to Software as a Service (SaaS) related research, III has gathered 10 domestic companies to participate the co-operation plans for education cloud, manufacture cloud, … and practice cloud, a total of nine cloud services. However, they are all in the early stages without much success stories or usages.

The study of this thesis is angled toward business needs, from the point of resource-based analysis to see how a firm will be affected if introduction of SaaS to business. In particular, we will study this subject from four dimensions, which are the competitiveness of enterprises, IT outsourcing strategy, cost structure analysis and data security technology, to identify the possible critical factors for the introduction for cloud computing services. As most people are perceived, cloud computing has a comparative advantage of cost saving over traditional approach.
