Virtualization is one of the most used technologies in computer networks today.
Virtualization allows distribution of physical resources via a special system among physical
machines. The technology brings about many advantages, including optimum usage of
energy and resources, improved troubleshooting, isolation and optimization of user
applications, increased security and performance, among others. The number of information
technology companies, whether developing open-source or business packages, who have
entered the virtualization market is constantly increasing. Global studies show that a huge
body of technical information exists about the virtualization technology; however, experts in
the field will gain the most advantage from a brief and clear comparison study of
functionality and performances of full-function and business versions of the approach.
This study evaluates performance and functionality of two software programs with the largest
market shares, developed by VMware and Microsoft: VMware 5.5 and Hyper-V 2012. First
we will look at the architecture, structure and requirements of the two applications to
compare key features like scalability, functionality, compression, key resources usage, etc.
Than we compare the key performances and resource usages of the two applications when
installed on similar systems. The results help organizations to choose the best solution for
their virtualization infrastructure .
We also find dramatic differences in the performance isolation provided by different
hypervisors.However, we find no single hypervisor always outperforms theothers. This
suggests that effectively managing hypervisor diversityin order to match applications to the
best platform is animportant, yet unstudied, challenge.
