PERSONAL VM MIGRATION SYSTEM AND A METHOD THEREOF BETWEEN CLOUDS IN A CLOUD COMPUTING ENVIRONMENT

摘要

PURPOSE: A personal VM migration system and a method thereof are provided to reduce dependency about a cloud platform by moving a VM which a user configures between cloud platforms.;CONSTITUTION: A VM image generating unit generates a VM image in a second cloud based on an updated file by a user for operating a VM in a first cloud. A VM reproducing unit reproduces a VM of the user by using the VM image. A CoW(Copy-on-Write) file system(220) divides the updated file from original data of the VM. A VM storage system(230) stores the updated file and the original data.;COPYRIGHT KIPO 2012
