AKS / VM pricing by resource-usage?

Question

Hello there,

I have a cluster which runs on a node with for example 8 CPU and 32GB RAM.
I also have a HPA (Horizontal Pod Autoscaler) that increases the number of Pods depending on incoming requests and resource useage.

I now want to set a resource-limit in kubernetes, how many CPU and RAM a single pod can use at max, and if this limit is reached, I want to add a new pod on this node.

So if there is only a few requests, only one pod is running and it is consuming lets say only 1 CPU and 2GB RAM.

So until there are many requests => more pods => more Resource usage, I pay For the other 7CPU and 30GB RAM without using it.

Is it possible to set up Payment per bandwidth or resource-usage?

Or can I only choose a VM-Size for a Cluster and always pay the whole price?

Hi @previousversiondocs

Thanks for reaching Microsoft Q&A

For now, the options that we have for saving cost are below:

• Use spot nodepool "https://learn.microsoft.com/en-us/azure/aks/spot-node-pool"
• Use can have the option to stop the entire cluster or only the nodepool to save cost "https://learn.microsoft.com/en-us/azure/aks/start-stop-nodepools" or "https://learn.microsoft.com/en-us/azure/aks/start-stop-cluster?tabs=azure-cli"
