A Survey of Virtual Machine Placement Techniques and VM Selection Policies in Cloud Datacenter
نویسنده
چکیده
The large scale virtualized data centers have been established due to the requirement of rapid growth in computational power driven by cloud computing model . The high energy consumption of such data centers is becoming more and more serious problem .In order to reduce the energy consumption, server consolidation techniques are used .But aggressive consolidation of VMs can lead to performance degradation. Hence another problem arise that is, the Service Level Agreement(SLA) violation. The optimized consolidation is achieved through optimized VM placement and VM selection policies . A comparative study of virtual machine placement and VM selection policies are presented in this paper for improving the energy efficiency. KeywordsServer consolidation, SLA violation, over loaded host, virtual machine. __________________________________________________*****_________________________________________________

متن کاملCommunication-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...
متن کاملDynamic Resource Provisioning in Datacenters using Profitability-aware VM Placement
With the ever-spreading user-base in cloud datacenters, it has become increasingly challenging to satisfy each user’s service demand. Resource requirements or service demands of cloud users are embedded in virtual machines (VM). Virtual machines are software extensions of physical machines such that a single physical machine can generate a number of virtual machines and hence, can service multi...
