Cloud computing is not a new technology, it is a new way of delivering computing resources. Elastic cloud computing enables services to be deployed and accessed globally on demand with little maintenance by providing QoS as per service level agreement (SLA) of customer. The Cloud-based DDoS attacks or outside DDoS attacks can make ostensibly legitimate requests for a service to generate an economic Distributed Denial of Service (eDDoS) -- where the elastic nature of the cloud allows scaling of service beyond the economic means of the purveyor to pay their cloud-based service bills which leads to Economic Denial of Sustainability (EDoS). Attacks mimicking legitimate users are on the climb. For cloud computing to remain attractive, the DDoS threat is to be addressed before it triggers the billing mechanism. This problem can be addressed by using reactive/on-demand in-cloud eDDoS mitigation service (scrubber Service) for mitigating the application-layer and network-layer DDOS attacks with the help of an efficient client-puzzle approach.
