OpenStack的一些抓图

[oneleaf]

随便杂散的抓了一些图，给没有接触过openstack的一些直观的印象。

并不是openstack的功能有多强大，而是提供了丰富的API，可以自己写代码来控制，这个才是最关键的地方。

[eexpress]

普通小公司/用户，能用这做什么。似乎只能玩玩。挂bot，开vpn。

[oneleaf]

用于搭建虚拟机，将一台服务器分割为其它的小服务器使用。

[susbarbatus]

我们公司测试部门在用这个，因为除了一些性能测试之外很多功能性的测试不需要机器多好，只要坑多就行，需要的时候随时开一台干净的出来部个系统上去。

[phoenixlzx]

只用 devstack 部署成功过一次，这玩意真心难搞啊...必须按照manual一步步来不能有一点差错。

[oneleaf]

这个是针对应用的基本参数，可以了解到命令的强大。
