Attacks in the Resource-as-a-Service (RaaS) Cloud Context

The Infrastructure-as-a-Service (IaaS) cloud is evolving towards the Resource-as-a-Service (RaaS) cloud: a cloud which requires economic decisions to be taken in real time by automatic agents. Does the economic angle introduce new vulnerabilities? Can old vulnerabilities be exploited on RaaS clouds from different angles? How should RaaS clouds be designed to protect them from attacks? In this survey we analyze relevant literature in view of RaaS cloud mechanisms and propose directions for the design of RaaS clouds.
