As the major economic driver behind running a Cloud Computing service is charging the customers according to their
actual usage (e.g. workload caused), another major effect of a flooding attack on a Cloud service consists in raising the bills for Cloud usage drastically. There are no “upper limits” to computational power usage3,thus the user running the flooded service most likely has to foot the bill for the workload caused by the attacker—at least if the attacker is not determinable
itself (cf. [24]).
