The number of vCPUs you can provision in Azure Virtual Machines is limited by quotas for each VM size family and a maximum number for each region. Blue Matador automatically monitors the number of provisioned vCPUs on your account and creates warnings when you are close to the limit.
If you are at the limit of the overall region quota, you won’t be able to deploy any more virtual machines in that region. If you are at the limit of one of the size family quotas, you won’t be able to deploy any more virtual machines of that family.
You can request for the quotas to be increased by opening a support request within the Azure portal.
