Research on Cross-Cluster Migration Technologies

Abstract

To solve the problem that OpenStack cloud platforms can not well support the migration of virtual machines across clusters, several cross-cluster migration technologies are proposed. Based on a novel multi-cluster collabrative architecture, a cross-cluster static migration approach and a cross-cluster live migration approach are provided. The experiments of comparing our approachs with the original intra-cluster migration are carried out. The results show that the proposed approaches have nearly the same migration time cost but gain better performance in disaster tolerance.
