Research and practice on the theory of private clouds migration

Currently, cloud computing is experiencing the rapid development. However, cloud migration is firstly required for the adaptation of some application systems to new cloud computing environments. Consequently, theories and strategies of the cloud migration research have emerged to be hot spots. In spite of the availability of many successful economic plans and technical schemes in this field, few guiding plans with wide applicability have been devised based on the migration of the private clouds. This paper summarized the technical principles and the general methods of the private clouds migration, and summed up a common method for private cloud migration. Subsequently, a specific case of migration from an enterprise system to the Eucalyptus cloud environment was completed based on proposed method, which indicated the feasibility and validity of this method. At last, through the analysis of system performances based on different migration methods, some technical suggestions for further development of the performances are also given in this paper.
