Quotas
Each project is assigned a quota which defines how much resources that a project can use. When resource consuming operations such as virtual machine creation are performed, the request is validated against the maximum quota permitted for the current project (as set by the environment variables or Horizon dashboard).
For shared projects, you can request additional resources via change project quota.
The project quota can be checked using:

| gigabytes_type | Total space in the volume storage class type such as standard |
| injected-file-size | Number of content bytes allowed per injected file. |
| injected-path-size | Number of bytes allowed per injected file path. |
| injected-files | Number of injected files allowed per project. |
| instances | Number of virtual machines allowed per project. |
| key-pairs | Number of key pairs allowed per user. |
| ram | Total megabytes of instance ram allowed per project. |
| security-groups | Number of security groups per project. |
