What is Virtual Networking?

Virtual Networking is a kind of technology which allows you to create and manage the networks of a physical computer virtually, as an overlay with hardware like cables, switches and routers. It can merge multiple physical networks into a single virtual network or even segregate a physical network into multiple individual virtual networks.

It uses software rather from traditional hardware to have the virtual network of your physical devices. It even allows you to move the virtual network machine to various locations without rearranging it.

How Virtual Networking Works?

Virtual Networking doesn’t change the primary setup of physical networks that have routers, switches, and cables. Instead, it offers an overlay of virtual connections between devices and physical networks. To put it in simple terms, Virtual Networking adds a digital connection to your devices or networks.

In most cases, Virtual Networks are managed by a software called Virtual Networking Stack, which checks the data traffic and ensures that the data reaches its destination. It even helps in determining where a specific kind of data should be stored and maintained.

Types of Virtual Networking

The most familiar types of Virtual Networking are Virtual Private Network, Virtual LAN and Virtual Extensible LAN. Let’s see what these types are.

1) Virtual Private Network (VPN)

Virtual Private Network (VPN) refers to a protected connection of devices to the central network over the internet. It helps in providing secured, encrypted and privatised access from any devices to the network. It is mostly preferred in workplaces to protect private files and data from any security breaches when a device is connected to access from a network.

2) Virtual Local Area Network (VLAN)

Virtual Local Area Network (VLAN) could be defined as a virtual connection of several devices and networks of LANs into a single network and these are connected in a logical manner. They are secured and maintain segmented traffic among the devices.

3) Virtual Extensible Local Area Network (VXLAN)

Virtual Extensible Local Area Network (VXLAN) helps in creating multiple VLANs on top of a single physical network. It encapsulates the Ethernet connection which is the warehouse of data within the IP packets. Compared to VLANs, VXLANs can create a large number of virtual networks.

Benefits of Virtual Network

There are numerous benefits of virtual networks, as witnessed over time. Let's have a look at those benefits:

1) Security

With Virtual Networking, you can accomplish improved access controls and can direct the traffic to individuals, groups and devices. This creates better security for your network. The more secure your network is, the less troublesome its function is.

2) IP Mobility

You can manage your IP address by hiding it while accessing the network. It enables easy mobility for the Virtual Machines (VM) across the network. It also helps in making disaster recovery and load balancing works flexible.

3) Simplification

The resources are managed by segregating them and thus are simplified for easy access. Even the data is stored in a way that is easily accessible and exchangeable to the users of the network.

4) Management

Instead of managing everything from a network in a physical mode, virtual network helps in managing them virtually. Through segregation of data and virtual joining devices, it provides better management for user access.

Challenges of Virtual Network

Afte knowing what is Virtual Network, it is evident that it possesses lot of benefits. However, it also has its own challenges.

1) Troubleshooting

To manage the networks in a virtual connection requires complex procedures and sometimes it needs troubleshooting. During the troubleshooting steps, you might have to consider both virtual network and physical layers since an issue might arise from anywhere.

2) Extra Layers of Management

The management of virtual network is done for both physical and virtual layers. This process makes it challenging for network administration since physical layers are additionally required to be managed.

3) Potential Security Exposure

When there is a vulnerability found in a single virtual machine or a misconfiguration with the network or devices, it could lead to security attacks for the whole virtual network. This makes it highly concerning since the whole network might be at fault.

Examples of Virtual Networking

Below are some examples of Virtual Networking:

1) Load Balancing

Load Balancing is used to optimise the performance and scalability of the network while focusing on distributing the network traffic between devices.

2) Hypervisor/Virtual Servers

A hypervisor is used to run multiple virtual machines at the same time over one physical server. It will act as a bridge between the virtual machines and the hardware of the devices.

3) Cloud Computing

To connect, store and deliver the data in any cloud-based applications, it requires network virtualisation. It delivers the data and all computing services over the internet.

4) Software-defined Data Center (SDDC)

Software-defined Data Center (SDDC) gets the help of Virtual Networking to virtualise the data infrastructure and to allocate the virtual resources as per the need.

Conclusion

In this blog, we explored What is Virtual Networking, its various forms, benefits, examples, and the challenges faced with it. In this digital era, why are you still living with physical servers instead of switching to virtual ones? Make your accessibility and storage as easy as turning on your system with Virtual Networking!
