Cloud data centers energy-saving scheduling algorithm based on CPU frequency scaling
The high energy consumption in cloud data centers has become an urgent problem. The scale and architecture of cloud data centers are growing increasingly immense and complex in recent years, which bring more severe challenges on the energy consumption management. This paper proposes new approaches for virtual machines (VMs) placement based on CPU frequency scaling. In the stage of initial VM pl...
متن کاملPower-performance tradeoffs in data center servers: DVFS, CPU pinning, horizontal, and vertical scaling
Dynamic Voltage and Frequency Scaling (DVFS), CPU pinning, horizontal, and vertical scaling, are four techniques that have been proposed as actuators to control the performance and energy consumption on data center servers. This work investigates the utility of these four actuators, and quantifies the power-performance tradeoffs associated with them. Using replicas of the German Wikipedia runni...
متن کاملCPU Frequency Scaling Algorithm for Energy-saving in Cloud Data Centers
High energy consumption becomes an urgent problem in cloud datacenters. Based on virtualization technologies, the pay-as-you-go resource provision paradigm has become a trend. Specifically, Virtual Machine (VM) is the basic resource unit in data center for resource migration and provisioning. Many researches have been devoted to improve datacenter resource utilization and reduce power consumpti...
متن کاملService resizing for quick DDoS mitigation in cloud computing environment
Current trends in distributed denial of service (DDoS) attacks show variations in terms of attack motivation, planning, infrastructure, and scale. “DDoS-for-Hire” and “DDoS mitigation as a Service” are the two services, which are available to attackers and victims, respectively. In this work, we provide a fundamental difference between a “regular” DDoS attack and an “extreme” DDoS attack. We co...
متن کاملResearch on CPU Workload Prediction and Balancing in Cloud Environment
Servers workload in the cloud environment should be balanced in order to achieve high efficiency and reduce resources consuming. One of the solutions is based on workload prediction, and design a proper load migration and balancing strategy. For the ease of discussion, we focus on CPU workload only in this paper. Specifically, considering the characteristics of workload, such as the strong corr...
