Most of the business could not invest on hardware as the maintenance part seems to be more expensive than the core installation. When business people sought a solution for this raising issue, the answer came up as Virtual networking which is a boon for every industry. Virtual network connects both virtual and physical machines to operate as interconnected network without physical connection.
The virtual network interface and virtual switches helps to manage the communication and connection effectively. The resource sharing abilities are managed by VM operating system which acts as single reference point.
Types of Virtual Network:
Basically the virtual networks are classified as External Virtual Network and Internal Virtual Network. Virtual Network connection can be established internally between two systems, devices, and IP address without any point to point hardware connection. External Virtual networks include Virtual Private Network (VPN), and Virtual Private Lan Service (VPLS) are some of the virtual network types that are widely used. VPN can be quite useful for the organization since there is no requirement of long distance leased lines. The cost of maintaining the servers are also very less. VPN offers high quality with best reach using public lines.
Advantages of Virtual networking
- Overhead expenses can be saved
- Investment cost on physical hardware such as cables and hubs can be reduced
- Centralized access control can be gained
- High network availability
- Security features are ensured
- Complexity of networks can be reduced
- Virtual network can be maintained easily
Virtual networking has a promising future with a networking infrastructure that will be collapsed into virtual environment. Virtual networks can save on budget as well as increase the speed and performance.
