Traffic-aware virtual machine migration scheduling problem in geographically distributed data centers

Abstract

In this work, we tackle the problem of VM migration scheduling in geodistributed DCs while considering fixed lifetime for VMs. We propose both exact and heuristic solutions that aim to find the best migration and placement decisions in a dynamic cloud environment. We consider networking VMs and we try to minimize the backbone traffic. The conducted experiments show the impact of the VM's lifetime on the migration decisions and prove the effectiveness of our heuristic solution in terms of maintaining of system stability.
