前言:
Rackspace剛剛推出了免費的OpenStack私有云軟件,基于Ubuntu 12.04 LTS主機操作系統(tǒng)和KVM管理程序,只需下載一個ISO就能安裝OpenStack私有云,并且可以得到Rackspace 24x7的支持服務(wù),但是僅限20個KVM節(jié)點,并且目前不支持OpenStack的高可用性和虛擬網(wǎng)絡(luò)功能。
根據(jù)以前玩OpenStack的經(jīng)驗,下載了就急急的安裝是不明智的,先讀懂文檔、做好規(guī)劃、寫好方案,再去動手實踐,哪怕是測試。
那么我就一邊下載,一邊翻譯一下 Rackspace 官方知識中心的文檔。這應(yīng)該是第一次正兒八經(jīng)的翻譯官方資料,這個么,,,真的不是件容易的事情 。好多概念還是似懂非懂的,希望得到高人指教。
