This code base implements the Azure AKS Terraform Module available on Terraform registry(https://registry.terraform.io/modules/Azure/aks/azurerm/latest)
The code selects Azure v5 instances based on the Intel Xeon 3rd Generation Scalable processors (code-named Ice Lake) for optimal cost/performance, see more details here.
The code will create an AKS cluster with with one or many AKS node groups. The node group is a collection of Intel Ice Lake based v5 instance types using an autoscaling configuration. Within this example, we have provided parameters to scale the minimum size, and the maximum size of the AKS cluster.
As of March 2023, Azure AKS does not support the 4th generation on Intel Xeon scalable processors (code named Sapphire Rapids). We will update the module once Azure AKS supports the 4th generation Intel Xeon scalable processors.
