KOP Cost Management - Introduction - Rafay Product Documentation
Considerations
As organizations adopt and scale their K8s environments, they often find themselves running blind struggling to get to a ‘good enough’ appreciation of their cost structure. This slows down their journey significantly and doesn’t allow them to expand their K8s footprint with confidence.
Cost Management service enables organizations to:
More effectively operationalize and allocate costs across teams in shared cluster scenarios. This is done by collection and aggregation of very granular resource utilization metrics from clusters.
Open up access and provide real time visibility to cost metrics to Platform and Application teams filtered by their role. This increases transparency and reduces the time to execute on any ‘closing the loop’ cost optimization exercises.
Pre-requisites
- Enable Monitoring & Alerting when creating a blueprint with Cost Management. This helps to retrieve the cost metrics via Prometheus (metrics containing the usage of CPU, pod, etc.)
- For EKS clusters, necessary permissions are required to create the Cost and Usage Report (CUR) and to add IAM credentials for Athena and S3.
- The below cluster types have been tested and are supported:
| Name |
|---|
| EKS |
| AKS |
| GKE |
| On-premise Data centers |
Limitations
- Cost Management support is available for the cluster types EKS, AKS, MKS, and GKE.
- In case of having more than one node in a MKS cluster, user must find out the average cost of both the nodes as the CPU & Memory per hour accepts only one custom pricing. Multiple node pricing are not allowed.
- On enabling the Cost Management via blueprint (or) performing any updates to the cost management parameters, you must wait up to one (1) hour to view the changes in the Cost Management Dashboard.
