An Integrated Dynamic Resource Scheduling Framework in On-Demand Clouds *
Lei Xu, Zonghui Wang, Wenzhi Chen · 2014
The biggest advantage of employing virtualization in cloud is the ability to provi-sion resource flexibly which makes “pay-as-use ” model possible. However, since the workload of virtual machine constantly changes, it is still a challenge that efficiently schedule resource by migrating virtual machines among lots of hosts, especially with multi-objective to meet, like power and QoS constraints. In this paper, we present a dy-namic resource scheduling solution, named Smart-DRS, which can well determines when to schedule, which to schedule, and where to schedule. It is an integrated frame-work that aims to deal well with hotspot mitigation, load balancing and server consolida-tion which are classic problems to solve in on-demand clouds. The experimental results show that our framework strikes a balance between efficiency, overhead and instantanei-ty.
