Cloud computing 雲端運算 is computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a metered service over a network (typically the Internet). 它是服務而非產品, 把資源共享 軟件和資訊供給計算機及其他設備, 並透過網絡 ( 通常為國際互聯網 ) 作為一個計量服務 End users access cloud based applications through a web browser or a light weight desktop or mobile app while the business software and data are stored on servers at a remote location 終端使用者可通過一個網頁瀏覽器或一個羽量級的桌面電腦或智能手機應用程式, 去存取儲存在遠距離的伺服器的商業軟件和資料
3. Cloud services 雲端服務 Software (sometimes Application) as a service (SaaS) 作為服務的軟體 ( 有時是應用程式 ) (SaaS) Platform as a service (PaaS) 作為服務的平台 (PaaS) Infrastructure as a Service (IaaS) 作為服務的基礎設施 (IaaS)

Benefits 好處 Cost 省成本 Collaborative, or not 協作, 或不 Portable access anywhere (almost) 易於攜帶 在任何地方 ( 幾乎 ) 可隨時存取 Less support needed 所需支援較少 Scalable 可擴展 No licensing 不需牌照 Environmental 環保 Less hardware 硬件較少
Concerns 關注 Privacy 私隱 Security 安全 Control 監控 Ownership 所有權 Reliability 可靠性
http://en.wikipedia.org/wiki/cloud_computing Public vs Private Clouds 公共雲端與私有雲端的對比
Publicly accessible 公開存取 Free or pay per usage 免費使用或按次收費 The Public Cloud 公共雲端 No contract or commitment 沒有合約或承諾 Access via Web Services 透過 Web 服務來存取
The Private Cloud 私有雲端 Same as Public Cloud but for private/internal resources 跟公共雲端相同, 但是用作私人 / 對內的資源 Same benefits as Public Cloud but: 有公共雲端的好處, 且 : Maintain control of resources (security) 維持對資源的監管 ( 安全 ) Meets corporate requirements 達到企業的要求 Can scale out to the Public Cloud if desired 可擴展至公共雲端
