Priority-Aware Virtual Machine Selection Algorithm in Dynamic Consolidation

PACMan: Performance Aware Virtual Machine Consolidation

Consolidation of multiple workloads, encapsulated in virtual machines (VMs), can significantly improve efficiency in cloud infrastructures. But consolidation also introduces contention in shared resources such as the memory hierarchy, leading to degraded VM performance. To avoid such degradation, the current practice is to not pack VMs tightly and leave a large fraction of server resource unuse...

Availability-Aware Energy-Efficient Virtual Machine Placement Algorithm

—Availability, as a part of Service Level Agreement (SLA), is a critically important issue in cloud services, which are affected by server or network failures in datacenters. Cloud service providers seek to not only fulfill the SLA, but also simultaneously minimize their operating costs, which are dominated by the energy consumption. In order to minimize the impact of a server/switch failure o...

Power and QoS Aware Virtual Machine Consolidation in Green Cloud Data Center

Cloud computing is a technological way of managing large numbers of highly virtualized resources in such a way that they resemble a single large resource from management perspective. The cloud computing model—made promising by complicated automation, provisioning and virtualization technologies. Such shifts to the computational demands results in greater power consumption, increased operational...

Communication-Aware Traffic Stream Optimization for Virtual Machine Placement in Cloud Datacenters with VL2 Topology

By pervasiveness of cloud computing, a colossal amount of applications from gigantic organizations increasingly tend to rely on cloud services. These demands caused a great number of applications in form of couple of virtual machines (VMs) requests to be executed on data centers’ servers. Some of applications are as big as not possible to be processed upon a single VM. Also, there exists severa...
