Cost Optimization Feature (EA)

Context​

K8SaaS is based on Azure Kubernetes Service but also enables several transversal services such as log collection, DNS management, certificate management, backup, policy enforcement etc...

Our commitment is to keep k8saas the lightest possible. For now, an "empty" cluster (without customer workloads) works in a 2 B2ms node, ie 4vCPU and 16G of Memory.

With more than 1 year operating more than 100 clusters in production, the k8saas has identified the 3 main expense item:

  • the virtual machines
  • the storage
  • the log sink

With the k8saas pricing v1, the cost of k8saas depends only on virtual machines (the other expense items are covered by a custom rate). With the k8saas pricing v2, the cost of all cloud services will be charged directly to the customer.

To help you optimizing your billing, k8saas provides enablers / quick wins, per expense item.
