The Performance Cost of Virtual Machines on Big Data Problems in Compute Clusters
msra
摘要
To facilitate better management of large data-in- tensive compute clusters, many cluster owners and providers of cloud computing environments are lo- oking at virtualization technology as a potential solution. However, virtual machines exhibit per- formance degradation when compared with phys- ical machines since a virtual machine is unable to execute privileged instructions without first going through the virtualization software.
