Cloud resources allocation optimization

A method implemented at a computer system for intelligent allocation of resources in a cloud environment, the method comprising:

• receiving a request for allocation of a resource within the cloud environment that comprises a plurality of regions;
• identifying a plurality of subscriptions in each of the plurality of regions, each subscription associated with a quota indicating a total amount of resource in a corresponding subscription and a usage amount indicating an amount of used resource in the corresponding subscription;
• for each region in the plurality of regions,
• computing a total quota indicating a sum of quotas of the plurality of subscriptions and a total usage amount indicating a sum of used amounts of the plurality of subscriptions in the corresponding region;
• and
• computing a total usage ratio indicating a ratio between the total usage amount and the total quota;
• selecting a particular region in the plurality of regions into which to allocate the resource based on total usage ratios of the plurality of regions;
• selecting a particular subscription in the plurality of subscriptions in the particular region based on usage of resource in the plurality of subscriptions, comprising:
• determining a priority for each of the plurality of subscriptions in the particular region based on at least one rule, the at least one rule configured to balance usage of at least a particular type of resource;
• and
• selecting the particular subscription in the plurality of subscriptions in the particular region based on priorities of the plurality of subscriptions in the particular region;
• and
• allocating the resource that is requested for allocation from the particular subscription based on the request.

A computer program product comprising at least one hardware storage device having stored thereon computer-executable instructions that are structured such that, when the computer-executable instructions are executed by at least one processor of a computer system, the computer-executable instructions configure the computer system to perform:

• receive a request for allocation of a resource within a cloud environment that comprises a plurality of regions;
• identify a plurality of subscriptions in each of the plurality of regions, each subscription associated with a quota indicating a total amount of resource in a corresponding subscription and a usage amount indicating an amount of used resource in the corresponding subscription;
• for each region in the plurality of regions,
• compute a total quota indicating a sum of quotas of the plurality of subscriptions and a total usage amount indicating a sum of used amounts of the plurality of subscriptions in the corresponding region;
• and
• compute a total usage ratio indicating a ratio between the total usage amount and the total quota;
• select a particular region in the plurality of regions into which to allocate the resource based on total usage ratios of the plurality of regions;
• select a particular subscription in the plurality of subscriptions in the particular region based on usage of resource in the plurality of subscriptions, comprising:
• determining a priority for each of the plurality of subscriptions in the particular region based on at least one rule, the at least one rule configured to balance usage of at least a particular type of resource;
• and
• selecting the particular subscription in the plurality of subscriptions in the particular region based on priorities of the plurality of subscriptions in the particular region;
• and
• allocate the resource that is requested for allocation from the particular subscription based on the request.
