| ## Calculation aspects | ||||||
|
|
||||||
| A Kubernetes cluster consists of two parts: the control plane and pools, which are made up of node instances. The impact of the nodes is already calculated as part of the instance impact calculation (https://www.scaleway.com/en/docs/environmental-footprint/additional-content/instances-env-footprint/). The purpose of this page is to detail the calculation of the control plane's impact. | ||||||

| ### Ratio per control plane | ||||||
|
|
||||||
| Kubernetes control planes are implemented on internal Kubernetes clusters composed of virtual machines and load balancers. | ||||||
| The cluster's impact is therefore, according to the RCP, the sum of the impacts of the virtual machines and load balancers. | ||||||
| For mutualised offers, the cluster's impact is distributed among the different customers. For the dedicated offers, the entire cluster impact is allocated to the customers. | ||||||
|
|
||||||
| ### Manufacturing impact | ||||||

| #### Calculation example | ||||||
|
|
||||||
| For the example below, we consider a dedicated kubernetes control plane made of two instances with a dedicated manufacturing impact of 2gCO2e/hour each and a load balancer with a dedicated manufacturing impact of 3gCO2e/hour. We measure the impact of 100 hours. We make the following calculation: | ||||||

|
|
||||||
| ``` | ||||||
| KubernetesDedicatedImpact = (2 * 2 + 3) * 100 = 700 gCO2e | ||||||
| ``` | ||||||
|
|
||||||
| In the example, the dedicated manufacturing impact of a dedicated kubernetes control plane usage for 100 hours is 700 gCo2e. | ||||||

| In the example below, they are 0,065gCo2e/wh and 1,16, respectively. Considering a dedicated kubernetes control plane made of two instances with an electrical consumption of 6wh each and a load balancer with an electrical consumption of 5wh. Considering 100 hours of usage, the total usage impact comes down to: | ||||||
