Abstract: A computer system is configured to receive a request for allocation of a resource within a cloud environment that includes multiple regions. The computer system then identifies multiple subscriptions in each of the multiple regions. Each subscription is associated with a quota and a usage amount. For each region, the computer system computes a total quota indicating a sum of quotas of the multiple subscriptions and a total usage amount indicating a sum of used amount of the multiple subscriptions in the corresponding region, and computes a total usage ratio based on the total usage amount and the total quota. The computer system then selects a particular region in the multiple regions based on the total usage ratios, and selects a particular subscription in the multiple subscriptions in the particular region based on at least one rule that balances usage of different types of resources.
