A Microsoft offering that enables tracking of cloud usage and expenditures for Azure and other cloud providers.
Hi Chester,
Your Azure subscription can get disabled because your credit has expired or if you reached your spending limit. It can also get disabled if you have an overdue bill, hit your credit card limit, or because the Account Administrator canceled the subscription.
You can refer the below link for more information. Hope this helps.
