In this survey, we have introduced the recent reports and trends of this attack and its effects on the service availability on various cloud components.

IoT, industry 4.0, smart cities and novel artificial intelligence applications that require devices to be connected and ever present cloud platforms, provide an increasing wide range of potential zombie armies to be used in Distributed Denial of Service DDoS attacks which are omongst the most critical attacks under cloud computing environment. Considering the increasing usage of cloud services by government bodies poses an emerging threat to e-government and e-governance structures and continuity of public services of national and local government bodies. On the other hand, moving to cloud computing paradigm, new security mechanism and defense frameworks are being developed against all threats and malicious network attacks that threaten the service availability of cloud computing for continuity of public and private services. Therefore, the future outlook of this technology is optimisticly considered to be widely adapted in this domain. Cloud computing is the subject of the era and is the current keen domain of interest of organizations.
