How to stop auto instance creation?

Question

Hi Team,

Greetings for the day.

I would like to know, how we can stop auto provisioning of VM instances in azure cloud, like some people create 500 servers at a time using technologies like terraform etc.

We do not want user to create resources using such technologies.

Also, Can we put cap on VM instance creation here in azure cloud?

Thank you in advance for your help.

Best Regards,
Prathamesh Padosakar

Hello, @Prathamesh Padosakar !

How do I limit the number of VMs that are created?

First, there is a default subscription limit for the number of vCPUs available by VM size as well as by region:

• Increase VM-family vCPU quotas
• Increase regional vCPU quotas

You can check your current usage quickly using CLI or PowerShell (CLI shown below):

az vm list-usage --location "East US" -o table

Strict limits to the number of VMs are managed through RBAC, where only authorized individuals or entities responsible for maintaining the VM quota would be allowed to create VMs (either manually or through automation):

For additional monitoring, you can create budgets and alerts to ensure that you don't exceed budgets or project scope when deploying resources:

I hope this helps, Prathamesh!
