云计算下负载均衡的多维 QoS 约束任务调度机制
Multi-dimensional QoS constrained scheduling mechanism based on load balancing for cloud computing
摘要
Abstract
In cloud, the needs of the user’s QoS can be better met and the load balancing between physical hosts can be achieved depending on an efficient scheduling mechanism. The traditional scheduling mechanisms often concern only about the response time of tasks or security, and load balancing strategy is static. The overall performance of the cloud computing environ-ment needs to be improved. Based on the flexibility, virtualization and other new features of cloud computing, this paper proposes a task scheduling mechanism considering performance QoS and trust QoS of tasks. It uses virtual machine migration technology to achieve dynamic load balancing. Simulation by CloudSim2.1 shows the scheduling mechanism will not only improve satisfac-tion of customers but also achieve load balancing effectively.关键词
