Distributed cache memory data migration strategy based on cloud computing

摘要

In view of the huge scale of cloud computing, cloud computing systems face many problemsin terms of scalability and high availability. In view of the distributed data storage in the cloudcomputing environment, a recursion based N boundary network model is constructed. A datamanagement model is given on the basis of the data center network structure. A replica distributionstrategy and a copy selection strategy are designed to improve the data availability andload balance. On the premise of guaranteeing data availability, a data migration algorithm basedon coverage set is proposed, which uses node selection strategy to reduce the migration cost asmuch as possible. Data migration makes more machines dormant and reduces energy consumption.By comparing and analyzing the experimental data, the correctness and effectiveness of theproposed network topology, datamanagementmodel, and data migration technology are verified.In the edge cloud computing architecture, in order to ensure the response time of the cloud computingservice andminimize the data redundancy in the system, this paper proposes and analyzesthe 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 balanceof access network transmission and storage flexibly, a data migration strategy based on networkperformance is proposed, which ensures the real-time response of the service.
