Abstract: Systems and methods are provided for allocating resources between data centers. One example computer-implemented method includes determining by a first data center, in response to a request for resources, whether the resources exceed remaining resources of the first data center. In response to determining that the requested resources exceed the remaining resources of the first data center, the first data center reserves its remaining resources, appends an entry for the remaining resources to a ledger, and submits a request to a second data center to reserve a difference between the resources in the request and the remaining resources of the first data center. Then, in response to a time interval expiring without the reserved remaining resources being utilized, the reserved remaining resources identified in the entry in the ledger are released for use in a subsequent request for the resources.

Abstract: Systems and methods are provided for allocating resources between data centers in response to insufficient resources at one of the data centers. One example computer-implemented method includes determining by a first data center, in response to a request for resources, whether the resources exceed remaining resources of the first data center. In response to determining that the requested resources exceed the remaining resources of the first data center, the first data center reserves its remaining resources, appends an entry for the remaining resources to a ledger, and submits a request to a second data center to reserve a difference between the resources in the request and the remaining resources of the first data center. Then, in response to a time interval expiring without the reserved remaining resources being utilized, the reserved remaining resources identified in the entry in the ledger are refunded to the first data center.
