Paper Abstract:
|
There has been a growing interest within the networking community to look into the potential of virtualization. Existing research efforts have addressed the overhead of virtualization in challenging scenarios. Yet, there are important research challenges to be addressed. One of them is the overhead that occurs due to the VM live migration process. Commonly, this overhead is perceived on the clients side by a decrease in performance over services deployed in these VMs. In this paper, we made a preliminary statistical analysis of the overhead caused by the VM live migration process using both real and virtual environments. Our evaluation, which has been conducted through a series of measurements with Xen hypervisor, has shown that the VM live migration process significantly affects the normal operation of primary client's services (e.g., database operations and Web services). |
