The primary driver was the potential for server consolidation: virtualization allowed a single server to cost-efficiently consolidate compute power on multiple underutilized dedicated servers. The most visible hallmark of a return to the roots of computing is cloud computing , which is a synonym for data center based computing (or mainframe ...

In virtualization, input/output virtualization (I/O virtualization) is a methodology to simplify management, lower costs and improve performance of servers in enterprise environments. I/O virtualization environments are created by abstracting the upper layer protocols from the physical connections .
Data virtualization is an approach to data management that allows an application to retrieve and manipulate data without requiring technical details about the data, such as how it is formatted at source, or where it is physically located, [1] and can provide a single customer view (or single view of any other entity) of the overall data.
Within a server virtualization environment, applications are interconnected by what is referred to as a virtual switch, which is very different from high-performing hardware-based network switches offered by the likes of Juniper Networks and Cisco Systems. Virtual switches are software-based switches and rely on the movement of packets up and ...
Pros. Permits torrenting and P2P on most servers. Private logging policy allows maximum safety and security. Works optimally in China and other censored regions. Unlimited concurrent connections. Cons
Hardware virtualization is the virtualization of computers as complete hardware platforms, certain logical abstractions of their componentry, or only the functionality required to run various operating systems. Virtualization emulates the hardware environment of its host architecture, allowing multiple OSes to run unmodified and in isolation.
