The Key Technology Research Of Dynamic Data Migration In Cloud Computing

In recent year, Cloud Computing have come into our view. For developers, it offers more storage and computing power to run their applications. For end-users, they would get more benefits. A person who uses the web applications is no longer completely bound to a PC, a location or a network. No matter where he is, he can access to applications and files just he wants. With its unique computing method, Cloud Computing has become the mainstream technology and gradually developed.Data migration is a key part of the data system integration to ensure smooth system update. It also plays an important role in cloud computing. The quality of data migration is not only an important prerequisite of the appliance of the new system but also a guarantee of the stable operation of the system. In this paper, the experiment is done on the autonomous cloud computing. Data migration strategy is applied in the autonomous cloud computing system to optimize and improve the performance of the service of cloud computing. The effective implementation of the dynamic migration strategy and autonomy is a hard nut of the paper. The main works of the paper are:(1) In this paper we proposes the architecture of autonomous Cloud System, and set up automatic monitoring module for each node,this module can manage the state of itself.(2) On the basis of fully understanding existed data migration technologies, we compare and analyze data migration algorithms. Based on autonomous Cloud service model, we propose the dynamic data migration algorithm firstly.(3) The experiment result indicates that the algorithm of dynamic data migration in autonomous Cloud service model is reasonable and feasible and dynamic data migration strategy balances the system processing power and computing power.
