A Virtual Network is an online connection that allows the users to stay connected virtually irrespective of the time and distance across various devices, servers, and virtual machines. They are able to have this facility with the help of software and wireless technology that is designed in a way that helps in making sure that the users do not lose the connection despite geographical differences. A Virtual network also makes it easy for the users to fix and troubleshoot problems. With the help of Virtual Networks, businesses all around the globe have been able to make significant changes in the way they operate and the same has reflected in the productivity levels of business organizations.
What is a Virtual Network?
In simple words, a virtual network can be defined as a connection that is used to stay connected without the differences in boundaries, time and place all across the world. It is a simple software connection that has been successful for businesses in increasing efficiency and productivity. The main difference between a Local Area Network (LAN) and a virtual network is that while LAN has a wired connection and is connected to all other devices with the help of a wired connection, a virtual network is a completely wireless connection.
How does a Virtual Network connection work?
A virtual network uses wireless software technology to be of the highest value and add asset to the existing software network. The following are the components that are used by a virtual network.
- Firewalls and Securities: Firewalls act as a barrier to monitor and stop any kind of potential threat to the business.
- Virtual Network Adapter: It acts just like a charger to the mobile phone. It serves as the main provider or the host for all the networks associated.
- Virtual Devices: They are necessary to initiate any kind of functions virtually and basically are used to initiate an action.
- Virtualization Software: The virtualization software is an important aspect of virtual networking as it helps in setting up a host network for the virtual network to function.
Classes of Virtual Network: VPN, VLAN & VXLAN:
Virtual Private Network (VPN:
A Virtual Private Network (VPN) is network connectivity that takes the help of the internet to connect two or more existing connections. The VPN allows the users to login from anywhere around the world into their respective accounts to access the physical networks that are formed through a connection. The best advantage of a VPN is that it gives a secure connection without the fear of any phishing attacks or data threats. The scope for a VPN is smaller in nature.
VLAN (Virtual Local Area Network):
A Virtual Local Area Network (VLAN) is used to connect the existing two or more physical network connections on a ground level. It is a group of virtual computers and devices that use a shared communication network line to connect a wireless link within the same geographical locations. This is beneficial to connect a collection of local networks in a specific location.
Virtual Extensible Local Area Network (VXLAN):
A Virtual Extensible Local Area Network (VXLAN) is a connectivity that uses tunnelling for layer 2 connection over the existing layer 3 connections. The tunnel feature here involves the virtualization of the networks that are geographically remote connections. A VXLAN is primarily used in the physical networks to run with the enabling of the virtual networks.
With the fast-paced world, the concept of virtual networking plays a major part in providing fast, accurate and concise services to its users. Virtual Networking has proven to be of immense help to start-ups as well as huge business conglomerates that focus on providing digital security, monetary savings, and time efficiency that prove to be the key indicators of a successful virtual networking experience.
