Billing
Warning-label
This version of Rahti is deprecated. The projects need to be migrated from Rahti 1 platform to the new Rahti 2 production platform by June 2024. Please consult the migration guide for more information.
Terminology
- Billing unit (BU): A unit used for billing at CSC - each resource consumes a given amount of BUs per hour.
- CSC computing project: A placeholder for the user's resources information - including: the number of BUs and the CSC services which are available for use.
- OpenShift project: A Kubernetes namespace with additional annotations.
Billing model
NOTE: Starting from 1.02.2020, using Rahti 1 consumes CSC Billing Units.
Billing units are calculated by scraping usage data from all of the OpenShift projects owned by the user. These calculations are based on:
- Pod core usage (per core hour)
- Pod memory usage (per RAM GB hour)
- Persistent volumes (per TiB hour)
The rate at which billing units are consumed depends on the size of the resources. Billing units are consumed as follows:
| Resource | Billing units |
|---|---|
| Pod core hour | 0,5 |
| Pod RAM GB hour | 1 |
| Storage TiB hour | 3 |
Cost will be calculated based on actual resources request with cpu, ram and storage rather than actual usage. Currently, Rahti 1 does not bill for the stored images.
For example, let's say you create a pod with the following specs:
- 0.2 cores
- 512 MiB RAM
You also create a persistent volume of size 10 GiB and attach it to the pod. The cost in BUs can be calculated as follows:
