Cloud data centers are becoming crucial to obtaining various digital services for enterprises and AI applications. However, with the growth of cloud environments to hyper-scales, architectures of traditional networks could not cope well with traffic; some of the difficulties encountered include congestion, latencies and inefficient use of resources. Software Defined Networking has come a long way in transforming the conventional approach to networking where the control layer is separated from the forwarding layer to be managed and controlled in a centralized manner in relation to the network traffic. The following paper examines the ways in which new SDN deployment applications can positively impact the traffic management structure of hyper-scale cloud data centers. The paper examines specific SDN-based approaches to control the flow, dynamic load, and adaptive QoS. As a result of the research, the features of using SDN opportunistic architectures in contrast to conventional Network Systems are presented with a focus on programmability, automated control, and scalability. In addition, we present how AI and ML may be used at the Software-Defined Network (SDN) controller level to improve real-time traffic decision-making and/or predictive analytics. As a result, to prove SDN's ability to perform in hyper-scale solutions, we run simulations and realistic examples. The findings revealed improvement in the large network performance in efficiency, low latency, and high bandwidth utilization. Last, we present the threats and limitations, such as security, compatibility, and reliability, with their possible solutions and the future research areas for SDN-based cloud networking. The work presented in this paper adds value and fitting to the development of SDN towards high scalability and simplicity, as well as intelligent and auto-configuration within cloud data centre environments and other related domains
