- Để tránh việc sử dụng hết tài nguyên, ta có thể thiết lập
quotasđể giới hạn tài nguyên có thể được sử dụng trên project.
| Quota name | Description |
|---|---|
| cores | Number of instance cores (VCPUs) allowed per project. |
| fixed-ips | Number of fixed IP addresses allowed per project. This number must be equal to or greater than the number of allowed instances. |
| floating-ips | Number of floating IP addresses allowed per project. |
| injected-file-content-bytes | Number of content bytes allowed per injected file. |
| injected-file-path-bytes | Length of injected file path. |
| injected-files | Number of injected files allowed per project. |
| instances | Number of instances allowed per project. |
| key-pairs | Number of key pairs allowed per user. |
| metadata-items | Number of metadata items allowed per instance. |
| ram | Megabytes of instance ram allowed per project. |
| security-groups | Number of security groups per project. |
| security-group-rules | Number of security group rules per project. |
| server-groups | Number of server groups per project. |
| server-group-members | Number of servers per server group. |
