軟件 str enc 強調 ofo provide opera 立場 software 大家常常聽到Private Cloud和On-Premise兩個術語，下面通過相關背景介紹區分兩者的差別：
Private Cloud定義
維基百科雲計算 詞條中解釋了Private Cloud，其含義為“Private cloud is cloud infrastructure operated solely for a single organization, whether managed internally or by a third-party, and hosted either internally or externally”，其關鍵是只為單一組織運作。
On-premises Software定義
維基百科On-premises Software 是指安裝在個人和組織機器裏面的軟件，對應的off-premises software通常是指“software as a service” ("SaaS") or “cloud computing”，其中強調“on the premises (in the building) ”是指自有。
Private Cloud類型細分
2類Private Cloud，分別為On-Premise和Hosted：
- On-Premise Private Cloud, often called Internal Cloud, is hosted within an organizations own offices, or data center, and provides an internal solution for hosting needs.
- A hosted Private Cloud solution is owned and operated by third-party service providers.
總結
從話術來看，公有雲廠家站在賣服務的立場，更願意把Private Cloud叫做“專有雲”，其實就是Hosted Private Cloud，並希望為該組織提供第三方的運維服務。
而傳統的設備廠家和軟件廠家，更喜歡把Private Cloud叫做“私有雲”，On-Premise Private Cloud，從而在強調“自有”的基礎上更好的賣軟件和硬件。
