Abstract:
Virtualization refers to technologies designed to provide a layer of abstraction between computer hardware systems and the software running on them. By providing a logical view of computing resources, rather than a physical view, This virtual view of the resources is not restricted by the implementation, geographic location or the physical configuration of underlying resources. Commonly virtualized resources include computing power and data storage and recently network sharing resources.
This research compare two virtualized environments ( Xen and Vmware), the comparison based on two criteria, the first measures the memory performance (RAM) and the second measures the processor performance (CPU) I offered same hardware specification to the both systems. And same size and structured of data , this data is part of ERP system that belong to one of Sudanese electricity companies.
The result that found show differences between two virtual systems, it is very small differences, further more the research appears that some case of large data XEN gives better performance result than VMWARE this due to better management provided by XEN.
