Mirantis 和 Red Hat 作為 OpenStack 商業化產品領域的兩大領軍企業,在行業內有重要的地位。因此,研究其產品版本發布周期和所支持的功能,對制定 OpenStack 產品的版本和功能規划有重要的參考意義。

3. 簡單結論
- RedHat 偏向穩健,Mirantis 更偏激進。
- Mirantis 的文檔已經非常好,但是 RedHat 的文檔更好,全面、詳細,堪稱完美。
- RedHat 將OpenStack功能明確區分為 “supported” 和 “tech Preview”,在選擇上更具大廠風范。
- Mirantis 的生態做得比 RedHat 更加全面。
- 對國內創業公司來說,RedHat 的信息更具參考價值。
注意:本文在作者收集到了更多信息,以及在兩家廠商發布新版本后保持持續更新。
