In view of the huge scale of cloud computing, cloud computing systems face many problems in terms of scalability and high availability. In view of the distributed data storage in the cloud computing environment, a recursion based N boundary network model is constructed. A data management model is given on the basis of the data center network structure. A replica distribution strategy and a copy selection strategy are designed to improve the data availability and load balance. On the premise of guaranteeing data availability, a data migration algorithm based on coverage set is proposed, which uses node selection strategy to reduce the migration cost as much as possible. Data migration makes more machines dormant and reduces energy consumption. By comparing and analyzing the experimental data, the correctness and effectiveness of the proposed network topology, data management model, and data migration technology are verified. In the edge cloud computing architecture, in order to ensure the response time of the cloud computing service and minimize the data redundancy in the system, this paper proposes and analyzes the data migration strategy and the pre stored data migration strategy for the network transmission, and gives the suitable application scene. On this basis, in order to control the balance of access network transmission and storage flexibly, a data migration strategy based on network performance is proposed, which ensures the real-time response of the service.
