二.nova-api 步骤3:nova-api接收请求 nova-api接收请求,也不是随便怎么来都接收的,而是需要设定rate limits,默认的实现是在ratelimit的middleware里面实现的. 然而有时候,我们希望实现distributed rate-limiting,从而Turnstile是一个不错的选择. https://github.com/klmitch/turnstilehttp://pypi.python.org/pypi/turnstile 步骤4:对Token的…
1. region 更像是一个地理上的概念,每个region有自己独立的endpoint,regions之间完全隔离,但是多个regions之间共享同一个keystone和dashboard.(注:目前openstack的dashboard还不支持多region) 所以除了提供隔离的功能,region的设计更多侧重地理位置的概念,用户可以选择离自己更近的region来部署自己的服务. 2. cell cell是openstack一个非常重要的概念,主要用来解决openstack的扩展性和规模瓶颈…
