Shin-ichi Kuribayashi

TL;DR
This paper presents a method to enhance QoS and reduce power consumption in cloud environments by dynamically applying WAN accelerators during virtual machine migrations, achieving significant power savings.
Contribution
It introduces a novel approach of using WAN accelerators dynamically during VM migration to maintain performance and cut power use in cloud data centers.
Findings
Power consumption reduced to one-tenth with WAN accelerators.
Dynamic WAN acceleration maintains QoS during VM migration.
Active WAN accelerator deployment improves energy efficiency.
Abstract
The widespread use of cloud computing services is expected to deteriorate a Quality of Service and toincrease the power consumption of ICT devices, since the distance to a server becomes longer than before. Migration of virtual machines over a wide area can solve many problems such as load balancing and power saving in cloud computing environments. This paper proposes to dynamically apply WAN accelerator within the network when a virtual machine is moved to a distant center, in order to prevent the degradation in performance after live migration of virtual machines over a wide area. mSCTP-based data transfer using different TCP connections before and after migration is proposed in order to use a currently available WAN accelerator. This paper does not consider the performance degradation of live migration itself. Then, this paper proposes to reduce the power consumption of ICT…
