中文摘要 | 雲端運算(cloud computing)是新一代的網際網路,簡單來說,雲端運算是指在網路上各種應用的服務,也指提供這些服務的軟體和硬體。雲端運算主要的優點是計算的資源虛擬化,因而電腦的硬體與軟體的需求大大的減少,大多數的程式都可以在網路上使用,所以不需要安裝很多的軟體,直接在上雲操作即可。換言之,透過雲端運算讓使用更方便,企業將不須花費大量的金錢建設機房架構與IT設備,不需要安裝及更新軟體,而是將機房設備維護、網路管理與軟體升級交給雲端去處理。雖然雲端運算有這麼多的好處,大部分企業紛紛想移轉至雲端,但並不是所有的應用系統都適合移轉到雲端上,所以本文提出一個移轉到雲端的流程與步驟,並整理出影響企業雲端化移轉的五個構面:商業的價值、技術與架構、組織與環境、安全與隱私、風險與管理,而每個構面下分別有5到8個關鍵成功因素。我們進行兩階段實證,第一階段採用專家焦點座談的方式邀請3位專家學者們填寫問卷並共同討論,以私有雲的觀點來探討每個關鍵成功因素(CSF)的重要性,並排除較不重要的關鍵成功因素;第二階段篩選過的關鍵成功因素再設計成對比較問卷請7位企業與專家學者們填寫。最後,採用層級分析法(AHP)進行評估與分析,計算出每個關鍵成功因素之權重比率及其整體排序。總之,希望藉由此移轉至雲端的流程與步驟以及其關鍵成功因素之權重及排序提供企業或政府進行雲端化移轉之參考依據,能夠讓他們在移轉至雲端環境的處理過程更加地順利與成功。 |
英文摘要 | Purpose- Owing to many benefits of cloud computing, many more organizations are eager to migrate their applications and services to the cloud, but not all applications are suitable for such migrations. Hence, this paper proposes the processing steps and examines the critical success factors (CSF) for enterprise cloud migration. Design/Methodology/Approach- First, they list and sort out five dimensions of CSF that may impact the cloud migration: business value, technology and architecture, organization and environment, security and privacy, risk and reliability. Second, we make focused discussion with three experts or scholars to remove the less important factors and re-design questionnaires, and then invite seven experts or scholars to fill out the new questionnaires. Finally, we utilize Analytical Hierarchy Process (AHP) method to evaluate and analyze for finding the weight ratios and order sequences of CSF for enterprise cloud migration. Findings- This paper identifies the proposed processing steps, and weight ratios and order sequences of CSF for enterprise cloud migration. Also, the proposed processing steps and CSF of cloud migration can provide enterprises or government the reference model to make them migrate to the cloud more smoothly and successfully. Research limitations/implications- This paper lays emphasis on the study of processing steps and CSF on the private cloud for enterprise cloud migration. Practical/implications- Cloud computing is the next generation Internet; in short, it can provide virtualized computing resources for various applications and services. The enterprises can also save the cost of capital using cloud computing, they will not need to spend a lot of money to build data center. Hence, maintenance of IT facilities, network managements, and software upgrades can be hosted on the cloud. Originality/Value-The main feature of cloud computing is the virtualization, so the needs of computing resources are greatly reduced. Most of applications can be used on the network, so it is not necessary to install a lot of software and hardware that can directly operate on the cloud. In other words, they are more economic and convenient to use through cloud computing without installing and updating software. |
