A Comprehensive Research on Integration of Cloud with Software-Defined Network

Cloud computing, as one of the emerging technologies, is required to meet increasing and on-demand availability of all resources such as computing power, storage and networking. It provides the pool of resources and offers the mechanism to run various applications on Cloud Data Centers (CDCs). Cloud data centers are usually distributed across multiple sites. With the provision of distributed data centers, the need for their management and maintenance arises. Such circumstances lead networking capabilities to being implemented on larger scale. Software defined network (SDN) is the programming paradigm along with the NFV orchestration and incorporates the modular and dynamic network support for the cloud data centers provided and established by the cloud over the geographically separated places. In this paper, comprehensive study has been mainly conducted to highlight the need for the integration of both emerging and versatile technologies. We also cover challenges, issues and benefits which have to be considered in underlying architecture, models and devices.
