ARM on Azure - Using Azure Cobalt CPUs on Azure Virtual Machines and Azure Kubernetes Service

Shortlink: https://aka.ms/armonazure

This repo contains Details and documentation on how to deploy Azure Cobalt Arm–based processors on Azure for Azure Virtual Machines and Azure Kubernetes Service. Use the .azcli scripts as a template to deploy to Azure VMs and Azure Kubernetes Service.

Quota Check Scripts

Before deploying ARM64 resources, check your subscription's quota:

Bash Script Method

The check-arm64-quota.sh script checks ARM64 VM quota across multiple Azure regions:

# Make the script executable
chmod +x check-arm64-quota.sh

# Run the script
./check-arm64-quota.sh

This will output:

• ARM64 VM family quota by region
• Best regions for deployment with sufficient quota (>8 vCPUs)
• Recommended next steps

Terraform Method

The check-arm64-quota.tf script performs the same checks using Terraform:

# Initialize Terraform
terraform init

# Run the quota check
terraform apply

When prompted, type yes to proceed. The script will check ARM64 VM quotas across all specified regions and provide a summary similar to the bash script version.
