Yes or No?

● 「我的東西都存在雲端上，手機就是一臺 thin client」● 「要做雲端運算要建置大型機房，將電腦集中運用」● 「雲端運算使用虛擬化技術快速部署資源或獲得服務，可

以提高伺服器使用率」● 「我用 Hadoop 來做雲端運算」● 「我的軟體是 SaaS， 所 以是一種雲端運算」● 「我們建雲端機房」「我們製造雲端伺服器」● 「雲端運算使用貨櫃型資料中心」

雲端運算的定義

直接找最權威的美國國家標準局 (NIST) : http://www.nist.gov/itl/cloud/upload/cloud-def-v15.pdf

這份文件自起草後由各界發表評論，已經改到第十五版，在千錘百煉之後於2009 年 10 月 7 日定案，至今未再改變。定義如下：

Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models. (下略，請自行參照原文。)

三種Service Model

● Cloud Software-as-a-Service● Cloud Platform-as-a-Service● Cloud Infrastructure-as-a-Service

四種Deployment Model

● Private Cloud● Public Cloud● Hybrid Cloud● Community Cloud

五種基本特徵

● On-demand self-service 有需求時自助服務● Broad network access 普遍網路存取● Resource pooling 資源共享● Rapid elasticity 快速彈性佈署● Measured service 服務量測

網管人員：進行網路層面服務，如LB進行流量導向控制、CDN進行內容快取、Firewall進行特定服務阻斷或入侵防禦等

應用程式開發人員: 應用程式服務，為程式開發人員撰寫之應用程式，基於某應用程式平台上，服務特定領域之用戶

資料庫管理人員: 儲存服務為服務應用程式而存在之資料包存方式，一般以DBMS系統、noSQL方式或是檔案方式存在

IDC機房人員: 執掌儲存裝置之分配與指定之資料備份作業，亦負責雲端資料之完整性與安全性
