近年來雲端運算逐漸盛行且其已被許多企業採用，雲端運算所帶來的好處包含提供更好的連結、企業不同廠的無間隙合作，進而提高生產效率。透過現存論文的研究，我們發現企業導入雲端運算與使其和企業內企業流程成功結合為兩大企業成功的因素。然而，要如何導入與對雲端運算加以控制卻很少在現存論文中談及，更遑論企業在導入雲端前該做哪些準備等議題。本研究也透過文獻的探討提出兩個研究面向（管理面與科技面），文獻探討也發現，此兩面向為企業選擇導入公有雲或是私有雲的主因。再者，本研究提出兩個討論面向的同時，也與現存的雲端服務供應商討論此兩面向，希望能讓兩面向更加符合現存雲端狀況。根據這兩面向的基礎，本研究在此兩大面向下提出許多因素來探討企業導入雲端的準備度。本研究也進一步透過問卷的方式訪問現存有採用或是導入雲端的企業，問卷內容涵蓋上述提到的兩面向，進而透過所收集的資料之分析來探討真正影響雲端導入成功與否的因素是否與研究所提出的假設符合。研究結果發現，虛擬化與IT建設的有無與完善程度對於私有雲的導入成功與否有正向關係。而研究結果也指出，公有雲與私有雲兩種型態的雲端也有相互的關係。 / Cloud computing has been dedicated to providing several benefits, such as better connectivity and seemingly seamless cooperation between different plants, that improve firm performance. Previous research maintains that introducing cloud computing and combining it with companies’ processes are two of the prime factors that lead companies to success; however, the manner of implementing this technology and exerting control over it are rarely discussed, especially with regard to the preparation before a company’s official launch of cloud computing. A literature review enables us to propose two dimensions—technological and managerial concerns—of factors driving companies to introduce cloud computing through both private and public clouds. Moreover, after proposing the two dimensions, we examine them by conducting interviews with several companies in the hopes of making these dimensions more applicable and pragmatic in business. Because the purpose of this research is to prepare companies to implement cloud computing, we design a questionnaire based on the dimensions and undertake a survey with several companies that have implemented cloud computing to determine the underlying factors influencing the performance of cloud computing. The results of this research show that both of the virtualization and IT infrastructure readiness factors have positive impacts on private clouds, and the results also indicate a relationship between public and private clouds, which means companies that have adopted public clouds are more likely to succeed in adopting private clouds.
