Number of K8s per cluster in

Question

Hi,

When trying to build an estimation for container insights data volume (Azure pricing calculator -> Azure monitor -> Log Data Ingestion -> Estimate Data Volume -> Estimate data volume using Container Insights) there is a field called "Number of K8s per cluster"

What does this field stand for?

What is the difference between this and the field "Number of clusters" from the estimation wizard?

Thanks

Hi Assaf L,

Thanks for reaching out to Microsoft Q&A.

Number of K8s per cluster:

"Number of Kubernetes nodes per cluster" - A Kubernetes node is a worker machine in Kubernetes, which can be either a physical or vm, depending on the cluster. Each node contains the services necessary to run pods and is managed by the master components. The no of nodes per cluster is an important factor in estimating the volume of log data generated as more nodes usually mean more containers, and hence, more log data.

Number of clusters:

This refers to how many total Kubernetes clusters you are operating. Each cluster represents a separate instance of the Kubernetes environment running one or more nodes (as specified in the above field). Multiple clusters might be used for segmentation of workloads, redundancy, or geographical distribution, among other reasons.

The difference between these fields is essentially the scope of scale:

• No of clusters counts how many individual Kubernetes clusters you have.
• No of K8s nodes per cluster details how many nodes are within each of those clusters.
