Software Defined Network (SDN) refers to an approach to network infrastructure that virtualizes and abstracts network resources through software. In addition, software-defined networks are introduced to break free from the limitations of IP network infrastructure. Cloud computing refers to Internet-based computing. It is a service that places a program on a virtualized server on the Internet and calls it on a computer or smartphone whenever necessary. Currently, there is a proliferation of personal devices and cloud applications, which leads to increased network bandwidth. Cloud computing is a limitation in the expansion of cloud computing in IP networks, and SDN is applied to solve this problem. The structure of the cloud has a centralized cloud and a distributed cloud structure. Core Cloud is the most efficient for high-speed data processing because data processing in one place. However, the network length between Cloud and the user is the longest and most inefficient for data transmission. Distributed Cloud is not good for data processing speed than centralized cloud, but the network length between cloud and user is the most effective in high-speed data transmission. In this paper, we propose a Cluster Cloud with the Instance Exchange structure. Cluster Cloud exchanges Instance between the Cluster Cloud through instance information and the SDN information to selectively change to the core Cloud, Distributed Cloud structure. Therefore, although it is in the form of a centralized cloud, it is changed to a distributed form according to the movement of users to reduce the data usage of the overall network.
