5. 體系架構
雲端運算的產業三級分層:雲端軟體、雲端平台、雲端設備。
上層分級:雲端軟體Software as a Service (SaaS) 打破以往大廠壟斷的局面,
所有人都可以在上面自由揮灑創意,提供各式各樣的軟體服務。 參與者:世
界各地的軟體開發者;
中層分級:雲端平台Platform as a Service (PaaS) 打造程式開發平台與作業
系統平台,讓開發人員可以透過網路撰寫程式與服務,一般消費者也可以在
上面執行程式。
下層分級:雲端設備Infrastructure as a Service (IaaS) 將基礎設備(如IT系
統、資料庫等)整合起來,像旅館一樣,分隔成不同的房間供企業租用。
