今天主要来区别两个概念 quotas 和 flavors ,看看官方文档怎么说
1 quotas
To prevent system capacities from being exhausted without notification, you can set up quotas. Quotas are operational limits. For example, the number of gigabytes allowed for each tenant can be controlled so that cloud resources are optimized. Quotas can be enforced at both the tenant (or project) and the tenant-user level.
防止系统资源在 无提示的情况下被的耗尽,你可以设置quatas(配额) ,quatos 是运行限制,每个租户分配的资源可以被控制,一次来优化云资源,quatos 可以在两个层面上使用强化:1 租户 或者 2 租户的用户
2 flavors
In OpenStack, flavors define the compute, memory, and storage capacity of nova computing instances. To put it simply, a flavor is an available hardware configuration for a server. It defines the “size” of a virtual server that can be launched.
flavors 是用来定义一个nova计算实例的计算,存储能力的概念,也就是一台服务器可以获取的硬件参数。
