Depending on the computational power in control of the attacker,
a sideeffect of the direct flooding attack on a Cloud service potentially consists in that other services provided on the same hardware servers may suffer from the workload caused by the flooding. Thus,
if a service instance happens to run on the same server with another, flooded service instance, this may affect its
own availability as well. Once the server’s hardware resources are completely exhausted by processing the flooding attack requests, obviously also the other service instances on the same hardware machine are no longer able to perform their intended tasks. Thus, the Denial of Service of the targeted service instances are likely to cause a Denial of Service on all other services
deployed to the same server hardware as well.
