Claim 0:
1. A computer-implemented method for allocating resources between data centers in response to insufficient resources at one of the data centers, the method comprising:
in response to a request for resources, determining, by a first data center, whether said 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:
reserving, by the first data center, the remaining resources of the first data center;
appending, by the first data center, a first reserve entry for the remaining resources to a first ledger of the first data center; and
submitting, by the first data center, to a second data center, a request to reserve a difference between the resources in the request and the remaining resources of the first data center;

determining, by the second data center, whether said difference exceeds remaining resources of the second data center;
in response to determining that the difference does not exceed the remaining resources of the second data center:
reserving, by the second data center, the difference from the remaining resources of the second data center;
appending, by the second data center, a second reserve entry to a second ledger of the second data center; and
notifying, by the second data center, the first data center of the reserved difference; and then

in response to a time interval expiring without the reserved remaining resources being utilized, releasing, by the first data center, the reserved remaining resources for use in one or more subsequent requests for the resources.
