Network & Server Virtualization

Virtualization Overview

Using virtualization, traditional software and hardware resources -- such as operating systems, servers, switches, storage and network resources -- can be replicated in software, which can add impressive cost savings, agility, and flexibility to IT operations. One of the most common types of virtualization is server virtualization, which is used to consolidate traditional server hardware onto a smaller number of physical servers. Microsoft's Hyper-V and VMware's vSphere are the two most popular server virtualization offerings in the enterprise today.
