5. Quota Management¶
Table of Contents
With the Quota Management feature you have the USAGE of your OpenStack Cloud resources fully under your control. The principle is simple! With your client account you receive a defined maximum number of OpenStack resources (e.g. number of projects, vCPU, RAM, number of VM’s, number and size of storage volumes etc.) depending on your order and contract. You can now distribute these resources to your OpenStack projects and thus have full control over which of your projects uses how many resources. If you need a higher limit for certain resource types, e.g. vCPU, you can request this directly in the Cloud Service Portal©.
5.1. Example Quota Management vCPU¶
The following graphic illustrates the principle of quota management using the example of the vCPU resource type.
- Reseller 1: Allocated 110 out of 5000 vCPU’s to Client A (100 vCPU)& Client B (10 vCPU).
- Client A: (Production Customer)
- Allocated 10 of 100 vCPU’s to Project 1 (Develop).
- Allocated 80 of 100 vCPU’s to Project 2 (Production).
- Both projects have all their allocated resources already in use
- Client B: (Trial Customer)
- Allocated all 10 of 10 vCPU’s to Project 1 (Trial).
- Project Trial is already using 8 of the 10 vCPU’s.
