Hi Franciasco, Yas here, Azure Technical Trainer from worldwide learning.

When you say limit what do you mean, if you are talking about quotas, here is a link you can get some information on, e.g. you can only have 20 vCPU per region per subscription:

https://learn.microsoft.com/en-in/azure/azure-resource-manager/management/azure-subscription-service-limits#virtual-machines-limits---azure-resource-manager

In addition to that here is the documentation page on Microsoft Learn which outlines some basic limitations:

The key limit is "spot vCPUs" that you can find for each region in Quotas. You need to have more free spot vCPUs than what is needed for the VM size you are creating. The practical issue is that although Azure has a process that allows you to request more quota, they currently decline those requests. This kind makes it impossible to use for testing any spot VM sizes that exceed the (very small) spot vCPU quota your subscription has by default in each region.
