| Summary: | 碩士 === 國立交通大學 === 電信工程研究所 === 101 === To provide effective and reliable services, cloud datacenters need parallel computing and virtualization techniques. This thesis presents an improved virtual machine VM placement mechanism, called Energy efficiency and Quality of Service (QoS) guarantee VM Placement (EQVMP) to overcome the problem of unbalanced traffic load in switching on and off VMs for the purpose of energy saving. EQVMP combines of three key techniques: (1) hop reduction, (2) energy $saving$ and (3) load balancing. Hop reduction can regroup VMs to have lower traffic load among them. Energy saving techniques aim at choosing the appropriate servers. The proposed load balancing updates VM placement periodically. Our experimental results show that the proposed scheme can lower energy consumption and maintain QoS. We propose an evaluation score to assess VM placement in terms of energy, delay and throughput. Comparing to other existing placement policies, our proposed mechanism can enhance system throughput by 25% and can have better evaluation score.
