Network Virtualization: An Overview

Network virtualization can be used as turning point in eventually gathering all network resources to be placed on your desktop screen. So to begin with, how can network virtualization be achieved?

The installation of software and services on your computer is the first thing to do to manage the sharing of storage, computing cycles and applications. Furthermore, network virtualization can make the hardware and software lower their cost when it comes to running data centers and corporate networks. What’s good about network virtualization is its capacity to give the servers and the data managers the control to manage computing and storage capacity.
In some cases, software-based administrative entity provides storage virtualization, grid computing, and distribution of application services which are all considered useful since some multinational companies use this technology in providing network-like functionality on a single network system.

To further make things clear, it should be noted that network virtualization is classified into two which can be either internal virtualization or external virtualization. The decision of choosing what classification of network virtualization will be implemented depends on the preference of the company. So, how can the two network virtualization be defined?

In external network virtualization one or more local networks can be either put together or subdivided into virtual networks. However the aim of improving the efficiency of a large corporate network or data center remains as the main objective. Network switch is the main component of external virtualization wherein the administrator can organize systems which are actually connected to the local network into different virtual networks.

On the other hand, internal virtualization is just a single system which is configured with containers to create a network confine in a box. The good thing about internal virtualization is that, the single system is absolutely efficient since containers and pseudo interfaces can be separated.
