Computing and implementing a remaining available budget in a cloud bursting environment

摘要

Calculating a remaining budget in a cloud bursting environment, by a processor. Within a particular time window, a first cost is computed of allocated and released cloud hosts. A second cost is computed of the cloud hosts that are allocated and not yet released. A remaining budget is computed as a difference between a budget limit and a sum of the first cost and the second cost, at the current point in time. A third, estimated cost of allocated and not yet released cloud hosts; and a fourth, estimated cost of cloud host requests currently in progress are each then determined. A safe remaining budget is then computed by subtracting the third and fourth estimated costs from the remaining budget determined prior.
