If cloud was the buzz word of 2010, the new buzz word since 2013 is software-defined networking (SDN). As the number of devices in data center and applications continue to rise, the need for bandwidth, storage and computing power grows substantially. This infrastructure needs to be managed, maintained, updated, powered and cooled. As a result, the traditional data center model is becoming too costly and complex to sustain. Also, security threats are growing significantly. Distributed Denial Service of Attacks (DDoS) is one of the vital security threats. With the advancement of Software Defined Networking (SDN), defense mechanisms against DDoS attack has opened a new door to cloud computing environment. This paper discusses on some of the distinct features of SDN and how to make full use of SDN’s features to defeat DDoS attacks in cloud computing environments. The research results in this paper can be expanded to prepare a new architecture of SDN enabled secured IoT based cloud environment.
