介紹
Nova是OpenStack計(jì)算的彈性控制器硬猫。OpenStack云實(shí)例生命期所需的各種動(dòng)作都將由Nova進(jìn)行處理和支撐，這就意味著Nova以管理平臺(tái)的身份登場，負(fù)責(zé)管理整個(gè)云的計(jì)算資源、網(wǎng)絡(luò)恍箭、授權(quán)及測(cè)度刻恭。雖然Nova本身并不提供任何虛擬能力瞧省，但是它將使用libvirt API與虛擬機(jī)的宿主機(jī)進(jìn)行交互。Nova通過Web服務(wù)API來對(duì)外提供處理接口鳍贾，而且這些接口與Amazon的Web服務(wù)接口是兼容的鞍匾。
